    Yes, or any other N bootloader encrypted with tuya keys and crc'ed.

    Added after 2 [hours] 22 [minutes]:

    BL602 IR update - https://github.com/NonPIayerCharacter/OpenBK7231T_App/actions/runs/17263341611
    Added IRRecv_nPup pin role.
    Disabled ALTCP and many mbedlts features, + disabled coredump.
    Enabled 1M config by default (it works fine on 4mb module).
    192.168.4.1 default AP address.
    Enabled irRemoteESP by default. OTA binary is still about 20k lighter than latest release.

    Great progress, I may be able to test it soon, I may still have my first BL602 device with IR Receiver.

    Quick question - is this IRRemoteESP now back to interrupt method (with new HAL) or is it still timer based?

    Also, it would be nice to have unified method for enabling SSL and HTTPS in builds, so users can have it if they request it.
    Helpful post? Buy me a coffee.

    Everything is timer-based. + change interrupt is needed, which is not implemented in OBK on any chip.
    There are too many modifications in ir code for me to make sense of what is needed to change it to interrupts.

    on BL602 - I'm afraid I'm not seeing any IR activity on IOs tried - P4/P5/P14 - even with unknown IR flag. IR Receiver hardware works OK on BK7231N latest general release.

    only this when trying nPup, which is presumably wrong role anyway.

    Retested BL602 IR.
    WB2-12F module in ESP32/ESP12/ESP01 board.
    P14, nPup.
    Got unknowns until clear line of sight.

    interesting. P14 nPup - nothing for me even with remote in the receiver's face.

    Will try other BL module and/or find MagicHome with ir pads unpopulated. My receiver's a bit DIY but it's worked on other platforms so far.

    ESP32 development board with connected wires, capacitors, and USB-C cable on a blue service mat.

    Shortened data cable makes no diff. remote is fine. also testing with AC signals remotes on mobile phone ir

    Added after 42 [minutes]:

    This MagicHome is my best option for adding IR. It's only missing the resistor from IO to IR.

    Close-up of a PCB showing an empty resistor pad near the IR output.

    I measured 100ohm on a resistor to IR on another factory-fitted IR device previously, so that's what my DIY rig has on data line (as well as a bonus capacitor across VCC/GND). Is 100ohm agreeable? A safe bet to fill gap on this device?

    well well. every day is a school day.

    1k is indeed better. thanks.

    this is physical remote then 2 random AC remotes from MiRemote app

    hadn't ever converted it to OBK. Still factory.

    Not sure what's going on with your board but 1.18.95 was the start of the new SDK. I've not had issues with WiFi with BL602.

    Added after 15 [minutes]:

    To add that I thought I'd done a series of old to new SDK tests at some point and the transition seemed to be a success. I could replicate your journey tomorrow if needed.

    That's a very serious issue. AP safe mode still works, but WiFi client is dead.

    Well, are you able to run both those versions of them without problems?

    - 1.18.95

    I could try downgrading?

    I would need to remove powersave from 1.18.95 because it was broken in that release

    I have no PowerSave enabled I think.

    I will move my BL602 closer to router (it's 2 meters from router right now), and try again.

    Added after 19 [minutes]:

    Still no WiFi. Not even when placed directly on router and powered via onboard step down (it's a LED strip controller).

    powersave 0 set first - the plug has OTAd and connected again OK

    the bulb starts OTA and goes offline for a few minutes - comes back at same version as before and no reboot. not sure what state that device is in regarding partitions or anything. Anyway, the plug came up OK.

    Maybe it would be worth to check this on your side:
    Code: text Expand Select all Copy to clipboard
    
SharpBL602Tool.exe -b 200000 -p COM4 -wf full_binary_with_app_OpenBL602_1.18.57.bin
pause

    Maybe there is a tiny chance that this has affected something that breaks WiFi on new SDK.

    Interesting, so new SDK reads something from binary?

    Are you able to restore it to order without a firmware backup? Just with BLDevCube?
    Helpful post? Buy me a coffee.

    not entirely sure what you mean.

    I also tried flashing full bin with BLDC but

    but if OpenBL602 releases end up being the whole image they'll presumably already come with bootloader setup from new SDK - ie NOT 1.18.57?

    I didn't try yet myself so I am asking if it's possible to restore your BL602 now with BLDevCube (overwrite bootloader, etc,). I am not sure if i have a backup of my device.

    oh I see. yes. I usually erase between tests anyway and 2mb flash is all FF after full erase. recovery is just re-flash

    Reflashed this way and problem persists:

    I guess we need to update tutorials to use new flashing method.

    Update: I did full erase and it works now. So.... what survived in BL602 memory first flash and was breaking WiFI?

    I don't see why 1.4.8 should ever be used.

    unsure but when you do that kind of flash it'll erase only specific sections in the process. eg

    Will SharpBL602 code go into EF?

    IRRecv works, not sure about others.

    I am testing on this device: https://www.elektroda.com/news/news3889041.html

    @divadiow if you have time, you could check which flash sections actually breaks new SDK WiFi. Idk, write full full_binary_with_app_OpenBL602_1.18.57.bin, update to latest build, do full 2MB read, and then gradually write it back with more 0xFF bytes at the end.

    I planned to merge SharpBL602 into EF.

    What I know currently:
    - full_binary_with_app_OpenBL602_1.18.57.bin works on old SDKs
    - when overwritten with BLDevCube, but without full erase, full_binary_with_app_OpenBL602_1.18.57.bin still breaks newer SDK WiFi
    - once I do full erase and write with BLDevCube, my BL602 works with new SDK
    So it really looks like the culprit is not within first partitions, but somewhere later, like, idk, RF partition of BL602?

    There is no RF partition, but there is dts partition.
    Would wifi work for you if flashed with new bldevcube but without any dts after full erase?

Topic summary

The discussion centers on the NiceMCU XH-WB3S development board featuring the BK7238 SoC, initially suspected to be BK7231T but confirmed as BK7238. Users share experiences with flashing, testing, and porting firmware, including challenges with encryption keys, flash IDs, and bootloader compatibility. The BK7238 uses 2MB flash with varying encryption keys per chip, complicating universal firmware flashing. Tools like BKFIL and Easy Flasher (EF) are used for backup and restore, with EF supporting full flash erase and restore including bootloader. Flash ID support was extended to include missing flash chips to avoid CRC errors. Arduino SDK and Beken FreeRTOS SDK (version 3.0.70.1 and newer 3.0.76) are referenced for development, with partial support for BK7238 and related chips (BK7231N, BK7231U, BK7252). Porting efforts include adapting delay functions for 160MHz BK7238, resolving flashvars alignment issues due to 64-bit time_t, and addressing HTTP server and TCP socket stability problems in LWIP. OTA updates are functional but require correct image types and bootloader versions. Power save modes and their impact on peripherals like BL0937 energy meter and DS18B20 sensors are discussed, with some instability noted under power save. SPI flashing and UART flashing methods are compared, with SPI preferred for some devices. BK7231U (CC8000 chip) support is emerging, with builds available but some undefined references and boot issues. BK7252 camera module support is experimental, with encrypted flash complicating firmware use. Users report issues with DS18B20 sensor timing on BK7238 due to delay_us inaccuracies, partially fixed by new SDK delay implementations. Logging and MQTT load affect system stability and sensor reading consistency. The community shares flash dumps, toolchain links, and SDK forks to aid development and testing. Overall, the thread provides detailed technical insights into BK7238-based NiceMCU boards' flashing, SDK porting, peripheral support, and firmware development challenges and progress.
