Cozylife DS-1211AN 3Gang Touch Switch: 1MB BL602L10 [XT-BL12][DT-BL12] - Images, Firmware & Boot

Best answers

How can I get OpenBK/OpenBL602 running on this Cozylife DS-1211AN with a 1 MB BL602L10 chip?

Yes — the thread ended up showing that OpenBK/OpenBL602 can run on the 1 MB BL602L10, but you need the 1 MB-aware SDK/build path and a matching partition layout [#21438533][#21439639] The key fix was enabling `CONFIG_BL602_USE_1M_FLASH := 1`; once that was set, the device booted and EasyFlash worked [#21438533][#21438595] A tester confirmed a 1 MB BL602L10 device flashed successfully, joined Wi‑Fi, and saved settings using the `partition_cfg_1M_miegapele.toml` partition file plus the PR 1534 build artifact [#21456497] The stock 1 MB layout was a problem because its PSM partition was only 8 KB, which was too small for this firmware and caused boot/init/config-save issues; the revised layout used a larger PSM and adjusted/removing other partitions as needed [#21431575][#21442160] Later replies also noted that the 1 MB build works on 2 MB devices too, and that the standard release was later reported to boot on 1 MB hardware as well [#21619453][#21798426]

    indeed. excellent work!

    I wonder how many drivers we can get enabled. CHT83xx seems to be the most obvious one to include with a couple of posts now for devices with it in.

    FW partition @miegapele PT is 860kB wide.
    Last build File: OpenBL602_dev_20250213_222946.bin
    Size: 793444 Blocks: 1552 IO Block: 4096 regular file
    So we have 85.15kB ?

    Can we integrate both 1MB and 2MB builds together into Github builds?

    Thank you for testing!

    Don't worry about blank page - Web App is a Javascript addon fetched from Github, it's open source obviously, but it won't fetch if you don't have Internet connection.

    We might be doing rw's in incorrect region. When configured with AP credentials, it throws this warning

    plus - mine looks like have Boot mode all the time, i shorted io8 to 3v3 just once, since then any power-off-on is still in boot mode - fw doesnt load.

    also no logs

    Yes of couse, but this is based on new sdk, so that needs to be merged first

    I would try different wifi device, different protection settings, different MPF settings, also try simple password with only letters, somebody had issues with some symbols somewhere.

    Added after 2 [minutes]:

    Toml file is posted in post #20 in this thread. Not sure if it's really required.
    But it it boots to bootloader I would look for short with multimeter first.

    got 133ohm to the ground from that pin. Had 8k earlier if i remember correctly. maybe connecting 3v3 directly burned pullup.

    10k resistor should be between 3.3v and IO8 for uart download mode

    I have this board, NodeMCU-series Ai-WB-12F-Kit R237.
    Code: text Expand Select all Copy to clipboard
    
The module is equipped with BL602 chip as the core processor and supports Wi-Fi 802.11b/ g/n protocol and BLE 5.0 protocol. 

    The BURN button seems to be connected on one side directly to one of pins (IO8?) and second side is connected to VDD via 4.7k resistance. From IO8 to ground, I have 32k.

    I am not sure about that resistor requirement but it seems to be obeyed on the proto board I have. I don't even remember if I respected the resistance requirement in the past.... but I didn't brick any BL602 as far as I know. Or at least... I didn't brick them that way.

    then mine is bricked, got 3.1V there when powered on, when off as said 133om to ground.

    just shortened it to the ground for test, now i got 540ohm and no longer im in download mode (0.001V now), now i have to pull 3v3 to flash it.
    Anyway, cant see it booting, is there any log on serial ? what boundrate ? its silent for me.
    just opening com, powercycle, nothing.

    Software interface for microcontroller flashing with settings and logs.

    Yes, Open wifi is not working I tested that while porting, I think it might be possible to make it work, but did not try.

    While porting I had to set some PMF setting on the connect call to make connection reliable. Maybe you can try changing PMF on your router if It has such ability:
    It worked I think with all options for me.

    Wireless network security configuration on a router.

    Also try maybe WPA1 or WPA3.

    I tried to flash build from github form 1mb devices on my 2mb module and it works just fine:

    I did a invastigation of standard 1mb toml layout and it's not suitable for this firmware. It only has PSM partition of 8kb, and that is not enough to handle big config of 3600b, so config updates does not work. You need more.

    so your revised custom toml should be considered the required de-facto toml for 1mb devices?

    Idk what changed but it connected today. Doesn't matter what 802.11w MFP setting is on AP (Optional on mine).
    Wifi SNR is pretty good.
    Wi-Fi signal parameters: signal strength -53/-95 dBm, speeds 6.0 Mbit/s and 72.2 Mbit/s at 20 MHz band, MCS 7, Short GI.

    It doesn't feel stable tho. Requests are often timing out. Sometimes responses are incomplete. Can't create autoexec, gpio finder loaded properly only once and it basically kills it with loads of /api/pins requests ... after maybe 5 it stops responding. It is slightly faster after fresh reboot.

    Configuration page for the OpenBL602_FD438A7F module with several configuration options.

    Network loading time statistics

    Screenshot of browser developer tools showing network details for http://192.168.0.166/api/lfs/autoexec.bat.

    Screen area with the text drop file(s) or .tar here and file saving messages.

    Screenshot of the Network tab in browser developer tools showing various HTTP requests to IP 192.168.0.166.

    Notice that after Time 550 it stops managing memory ?

    My development module has the same problem. If connected to computer wifi is very slow/unusable. However, if
    I power it from separate usb charger, it works fine. Not sure why that is. I thought it was caused by my router upgrade, but probably not. Try connecting module to separate usb charger.

    No, not really. That is something I've made for testing.
    This would be more proper one, I has:
    • 64kb for boot loader/partition table
    • 912kb for firmware
    • 0kb for media partition, (required so that it currently does not crash)
    • 32kb for PSM partition (that's there config, energy stats and boot count is stored)
    • 16kb for factory partition (that's there dts file is stored)

    Some of this could be reduced/removed if somebody wants, for example to implement update.

    I'm on kinna external psu already. Pretty sure it's stable.

    That's nothing to do with any PSU issues, any computer can power such module. Much more likely it has something to do with noise coupled from the computer. You cannot avoid that unless you don't connect to a computer :) Also you might want to move the module away from the computer too for testing

    I wonder how much such a filter could help?
    Diagram of a capacitor input filter or Pi filter.
    Helpful post? Buy me a coffee.

    Powered it from fresh batteries and disconnected from everything. Stopped registering on ap. Tried a couple of times.

    Batteries hold at 3.37V. Reflashed with updated partition table. Disabled 802.11w MFP on AP. Put closer to AP (the only emf it gets comes from AP). Connected after 3rd attempt. Same behavior, gpio finder kills it. Wireshark tells what we already know.
    Screenshot of Wireshark showing TCP packets between IP addresses.

    Does the webserver api is complete in your port? I'm getting 404s on /api/lfs
    Screenshot of a developer tool showing headers for a failed HTTP request.

    Lmk if you have any suggestions what else could be checked.

    Tried everything above with one of my XT-BL02 chips. It's booting up with OpenBL602_1532_merge_d11ce44f3af6.bin but WIFI won't connect whatever I tried. Voltages 3.2-3.4 short/long cables. On saving wifi settings just resets. It does boot with standard 1M.toml and with partition_cfg_1M_miegapele.toml. With this *.toml from @miegapele it boots but infinite reboots.

    This is amazing, I'm happy I stumbled into this topic, because even some recent posts gave no hope for BL602L10.

    I have: https://pl.aliexpress.com/item/1005005989938860.html
    Inside it looks exactly like: https://www.elektroda.com/rtvforum/topic4039283.html, but it has BL602L10 inside. Same pinout works for UART and flashing. Even has the same PCB text: XLD-QFLWP-YT2.1. No need to desolder the module.

    It flashed fine, connects to WiFi and saves to Flash with:
    * this TOML: https://www.elektroda.com/rtvforum/topic4086736.html#21432034 (partition_cfg_1M_miegapele.toml on the screenshot)
    * this build file: https://github.com/openshwprojects/OpenBK7231...ions/runs/13334744916/job/37247362962?pr=1534, direct link: https://github.com/openshwprojects/OpenBK7231...actions/runs/13334744916/artifacts/2594275994

    Settings in Buffalo Lab Dev Cube 1.9.0 (I did flash erase on that chip in the past, it's not selected here):

    Microcontroller management program interface.

    This is my second BL602, I had way easier time with this one:
    * soldered jump wires
    * breadboard I trust
    * power supply backed by AMS1117 https://botland.store/power-modules/1482-supp...ontact-plates-mb102-33v-5v-5904422300739.html
    * CH340G usb2uart

    EDIT: exactly the same config from https://www.elektroda.com/rtvforum/topic4039283.html works

    OpenBL602 user interface with LED settings and device information.

    I got another 2 bulbs with exactly the same hardware (BL602L10), from two different sellers.

    I've dumped the flash for both. Flashed one with OpenBK. There are some differences in two address ranges: 0x000f8000-0x000f8690 and 0x000f9000-0x000f9980

Topic summary

✨ The discussion focuses on the Cozylife DS-1211AN 3-gang touch wall switch featuring a 1MB BL602L10 Wi-Fi and BLE module, manufactured by Shenzhen Dianling Intelligent Technology Co Ltd. The main challenge is adapting OpenBeken/OpenBL602 firmware, which typically targets 2MB flash BL602 chips, to the 1MB flash variant, as standard builds and tools like OpenBeken do not natively support 1MB BL602L10 devices. Key technical issues include flash memory partitioning, bootloader compatibility, EasyFlash storage initialization, and power supply stability affecting boot loops and Wi-Fi connectivity.

Significant progress was made by creating and testing custom partition table (TOML) files tailored for 1MB flash layouts, notably the partition_cfg_1M_miegapele.toml, which allocates appropriate sizes for firmware, media, PSM, and factory partitions. Firmware builds with specific SDK configurations (e.g., CONFIG_BL602_USE_1M_FLASH and CONFIG_BL602_USE_ROM_DRIVER enabled) successfully boot and run on the 1MB BL602L10, including OpenBK7231T_App builds from GitHub pull requests #1532 and #1534.

Power supply quality and wiring (shorter VCC and ground cables, decoupling capacitors) were critical for stable operation, as the module exhibited boot looping and Wi-Fi instability when powered inadequately or with noisy sources. The GPIO17 pin usage and UART download mode resistor requirements were also discussed for module replacement or debugging.

Wi-Fi connection issues were partially resolved by adjusting router PMF (Protected Management Frames) settings and using simpler passwords. The firmware supports AP mode and basic Wi-Fi functions, though some web API endpoints (e.g., /api/lfs) may be incomplete. The community shared detailed boot logs, flash memory dumps, and PCB images to aid development and testing.

Overall, the topic demonstrates successful adaptation of OpenBL602 firmware to the 1MB BL602L10 module in the Cozylife DS-1211AN switch, with custom partitioning, SDK flags, and power considerations enabling stable boot and Wi-Fi operation, while highlighting ongoing challenges in full feature support and stability.

FAQ

TL;DR: 1 MB BL602L10 modules run OpenBeken after setting CONFIG_BL602_USE_1M_FLASH=1, growing PSM to 32 KB and flashing a 793 kB image—"works on every sample we had" [Elektroda, miegapele, post #21438533] Why it matters: you can free cheap touch-switches and sensors from cloud lock-in with one flash.

Quick Facts

• Flash size: 1 MB (0x100000) [Elektroda, divadiow, post #21301826] • Working firmware: OpenBL602_1M build 793 kB [Elektroda, maxim2002, post #21438474] • Required PSM partition: 32 KB @ 0x0F4000 [Elektroda, miegapele, post #21442160] • Supply voltage: 3.3 – 3.6 V; keep GND & VCC leads < 5 cm [Elektroda, divadiow, post #21434069] • Typical flash time via DevCube 2 Mbaud: 16–18 s [Elektroda, niterian, post #21456497]

What change finally made 1 MB BL602L10 boot OpenBeken?

Defining CONFIG_BL602_USE_1M_FLASH := 1 switches the SDK to the alternate XIP flash routine (XIP_SFlash_Read_Need_Lock_Ext). This prevents EasyFlash from hanging at 0xE9000 and lets the board reach Wi-Fi initialisation [Elektroda, maxim2002, post #21438533]

Which partition table should I flash?

Use the 1 MB TOML posted by @miegapele: 64 KB boot+PT, 912 KB FW (0x010000-0x0F3FFF), 32 KB PSM (0x0F4000-0x0F7FFF), 16 KB factory DTB (0x0FC000). 8 KB PSM from the stock 1 MB table is too small and corrupts config saves [Elektroda, miegapele, post #21440834]

Why does the board reboot when I save Wi-Fi?

If PSM is only 8 KB the 3.6 KB config plus garbage–collection fills the sector, EasyFlash triggers GC every save and the watchdog resets. Expanding PSM to 32 KB fixes the loop [Elektroda, maxim2002, post #21438474]

How do I enter UART-download mode safely?

  1. Hold IO8 high through a 10 kΩ pull-up to 3.3 V. 2. Reset or power-cycle. 3. Release after handshake. Direct 3.3 V without resistor may destroy the internal pull-up; one user measured 133 Ω to GND after such short [Elektroda, chemik_16, post #21440354]

What’s the preferred flashing procedure?

  1. Pick DevCube 1.9.0, 2 Mbaud, 40 MHz clock. 2. Select the 1 MB TOML and the 1 MB OpenBL602 build (whole_img.bin & ro_params.dtb). 3. Erase, program, verify (≈17 s total). Verified SHA equals host value means success [Elektroda, niterian, post #21456497]

My module boots but loops every 3 s—why?

Long, thin supply leads add >100 mV drop during Wi-Fi TX. Shorten VCC/GND to <5 cm or power the module in-circuit. After trimming leads one tester eliminated the loop at 3.55 V [Elektroda, divadiow, post #21434069]

Does deep-sleep work on BL602?

Normal DeepSleep works; PinDeepSleep is not yet ported (available only for BK and XR chips) [Elektroda, insmod, post #21598541] Battery sensors such as TH01 will therefore drain faster than with XR modules.

Open Wi-Fi network won’t connect—edge case?

Yes. Current SDK refuses open (unencrypted) APs; WPA2-PSK connects reliably when 802.11w PMF is “Optional” [Elektroda, maxim2002, post #21441931]

Can I flash 1 MB firmware to a 2 MB module?

Yes. The 1 MB image boots fine on 2 MB BL602; the unused upper flash stays blank. OTA partition is omitted, so remote upgrade is disabled [Elektroda, miegapele, post #21440834]

How much free RAM remains after boot?

With full 1 MB build and Wi-Fi connected the board reports ~113 kB free; worst-case after WebApp stress it dipped to 18 kB before recovery [Elektroda, maxim2002, post #21441931]

‘No enough DESC 2(7)’ appears in log—danger?

It indicates the Wi-Fi driver ran out of TX descriptors during heavy HTTP polling; the stack recovers automatically but may drop the TCP connection [Elektroda, maxim2002, post #21441931] Keep polling intervals >100 ms.

How can I cut heat in the 18 W bulb?

Limit PWM brightness to 90 %. “Even at 90 % the RGBCWW bulb is visually identical but 8 °C cooler” [Elektroda, p.kaczmarek2, post #21599155] Add LED_Map 0 90 in autoexec.

Steps to build your own 1 MB image?

  1. Checkout OpenBeken dev branch and Bouffalo SDK 1.6.39. 2. In proj_config.mk set CONFIG_BL602_USE_1M_FLASH=1. 3. Place the 1 MB TOML in partition. Compile with make BL602L10_1M. Output should be ~793 kB [Elektroda, miegapele, post #21438328]
