BL602L20 from Aliexpress - where to connect BOOT for flashing?

Question

Hello again, once again friends from China, sent me another variant of the temp sensor with BL602 on board. This time, you have to solder out the battery connector to get to the pads, however, I am not missing a pad here boot . There is a DL and an EN instead. Where in this case to pass VCC...

divadiow · Accepted Answer

you don't use the single download method to initially flash OBK. This is for restoring whole flash backups Your BLDC should look like this with firmware, dts, boot2 and partition table set

p.kaczmarek2 · Answer

DL is a rather different nomenclature for BOOT, probably derived here from "DownLoad", "firmware download", which means "downloading the batch to the microcontroller".

In this topic you have pinout BL602:

BOOT is otherwise D8/GPIO8:

Indeed DL raised, lets flash the chip. One went from flash, but the second one is putting up something. Below is the configuration that went into the first sensor, and on the second it shows as if the flash is too big?:

When I discard dts and boot2, the flashing runs fine, but the device does not boot (first blinked LED and raised default AP)

Added after 27 [minutes]:

Apparently the board is the same, but the chip is already different, as it is a BL602L10:

You probably need to poke around. Colleague @divadiow in this thread had a similar problem and somehow solved it:
https://www.elektroda.com/rtvforum/topic4039283.html

Quote:

Bouffalo Labs BL602L20 (L=Light, 2=16mbit/2mb flash)

From this it would appear that BL602L10 is L=Light, 1 = 1MB Flash....

Maybe, for example, selecting Partition for 1M and not 2M would help. Just curious what about the application ... As the whole thing is made under the assumption that it is under 2MB. Possibly a separate build would have to be compiled.

Mad_Maxs · Answer

Unfortunately despite switching the partition to 1MB and successfully flashing, the device does not boot. I assume that what you wrote works and you would have to make a version for 1MB .

And what does the log on the UART show?

I'm looking into the makefile to see if it would be easy to change something: Code: BashLog in, to see the code Makefile bl602: I can't see at the moment where in this SDK it switches, but probably if you search longer you would find it.

Hello,

Earlier this month I received the same Tuya device (AIYATO-TH-V1). I managed to upload the firmware and have identified how the BL602L20 chip is connected to the sensor etc, but when enabling the CHT8305 and battery drivers, I get the message that these are not known in this build.

Some more info that I've identified so far:
- GPIO_0 = SCL
- GPIO_1 = SDA
- GPIO_3 = Wifi_led_n
- GPIO_12 = Btn
- GPIO_11 & GPIO_5 probably Bat_Relay & BAT_ADC, but to be confirmed
- The temperature and humidity sensor is a CHT8315.

Is this something that can easily be added/enabled in the build ?

divadiow · Answer

>>21014962 @gloorung the CHT8305/8310 driver is not enabled in the BL602 build currently afaik.

also, CHT8315 is newish and the existing driver was not programmed with it in mind so won't work yet anyway. 8315 is also being discussed here most recently https://www.elektroda.com/rtvforum/topic3945688-270.html#21101835

You probably need to poke around. Colleague @divadiow in this thread had a similar problem and somehow solved it:

@Mad_Maxs I'm sorry I totally missed this thread until today. I'm afraid I've never had a BL602L10 with 1mb flash. sounds a little tight for OBK. Did you get any further since February?

divadiow · Answer

Randomly I've just received a 1mb DT-BL02 BL602L10 module smart plug with BL0937. Will be interesting to see how OpenBL fits, if at all, when it comes to flashing it. Added after 10 [minutes]: success/OTA capability looks to depend on which 1mb toml file you use in BLDC partition_cfg_1M.toml Code: TextLog in, to see the code partition_cfg_1M_ota.toml Code: TextLog in, to see the code latest BL602 firmware is: UART OpenBL602_1.17.176.bin 752,152 bytes OTA OpenBL602_1.17.176_OTA.bin.xz.ota 402,972 bytes so it seems you should be able to successfully convert to OBK using partition_cfg_1M.toml but will not have OTA capability on 1mb BL602s, though I note from previous posts that this has been tried.

zakdma · Answer

Hi!

Does anyone make BL602L20 working?

I flashed it according to the instructions with the latest firmware OpenBL602_1.17.795.bin
GPIO8 to 3.3V through 10k resistor
RX and TX to the corresponding TX and RX of UART module.
Power 3.3V from a reliable separate PSU.
But it does not work. Looks like it does not boot at all after flashing. There is no noticeable current from PSU.
Here are the logs of the programming

It's been some time, but don't you need to disconnect BOOT pin first and then do power off and on?

zakdma · Answer

>>21342148 Yes, I did it of course.I even desoldered the CPU module from the main PCB, and soldered programming pins directly to pads on the back. Without any different results. Module keeps silence and there is no even a letter in the UART.

>>21342276 There are no such fields in the form on the IOT tab.There is a screenshot There is only the field Partition Table and dts and boo2 fields missing.I'm using the latest version of BLDC 1.9.0

Ah, I found it. Just need to select the partition table and these fields appeared.

Unfortunately it doesn't work either.

I tried these two files
- https://github.com/openshwprojects/OpenBL602/...device_tree/bl_factory_params_IoTKitA_40M.dts
- https://github.com/openshwprojects/OpenBL602/.../flash_tool/bl602/builtin_imgs/blsp_boot2.bin

And also I tried files from BLDC distributive

- C:\Users\user\Downloads\BouffaloLabDevCube-v1.9.0\chips\bl602\device_tree\bl_factory_params_IoTKitA_40M.dts
- C:\Users\user\Downloads\BouffaloLabDevCube-v1.9.0\chips\bl602\builtin_imgs\boot2_isp_bl602_v6.6.2\boot2_isp_release.bin

The same result. Programming finished but module keep silence.

probably the single download at the beginning overwrote the bootloader. restore your factory backup using single download mode then do OBK again using the other method.

zakdma · Answer

>>21342619

Thank you for the answer. But I have no factory firmware anymore.
When I first tried to flash your firmware I tried to read factory firmware first but it failed to read. I tried many times with no luck.
So I decided to flash it anyway with your firmware using single download mode, and obviously, I totally lost the factory firmware.
Is there any workaround for this?

divadiow · Answer

OK. You could try another device factory firmware then do OBK. try the one attached to this thread

Managed to get this device working on @miegapele PR with CHT83XX driver enabled.
Config is as follows:

{
  "vendor": "Aiyato",
  "bDetailed": "0",
  "name": "Cozylife Hygrometer White (Temperature Humidity)",
  "model": "BC148-WT",
  "chip": "BL602",
  "board": "Aiyato-TH-V1",
  "flags": "1024",
  "keywords": [
    "temperature",
    "humidity",
    "BL602"
  ],
  "pins": {
    "0": "CHT83XX_SCK;1",
    "1": "CHT83XX_SDA;2",
    "3": "WifiLED;0",
    "12": "Btn;0"
  },
  "command": "CHT_Calibrate -6.4 10",
  "image": "https://obrazki.elektroda.pl/2421821500_1709057362_thumb.jpg",
  "wiki": "https://www.elektroda.com/rtvforum/topic4039068.html"
}

User interface displaying temperature and humidity information with configuration options for the CHT8315 device.

Device seems stable so far, except that GPIO finder kills web server.
Attached binary and partition table.

insmod · Answer

But what would be the purpose for using it?
There is no deep sleep implemented for BL602.
There is no PinDeepSleep for BL602, which is what should be used when sensor is 8310/8315.
Without those, batteries will be drained very quickly.

Got 3V3 lines across the whole home. Not really bothered about batteries.

BL602L20 from Aliexpress - where to connect BOOT for flashing?
