Non-zero status code: BkFlashRead4KResp(status=6, start=0x0, data=bytes(1))

chip may or may not be supported, new to none esp, cannot tell

[kuba2k2]

Try running Get chip info.

It might be falsely detecting the chip type (T/N/etc) which could cause incorrect reading options.

Also, please post the full log of the flash operation (even better with enabled debug log level).

so is this chip supported by libretiny platform, or did i just wasted my money , i thought all 7231 is supported so i bought too much of them at once

[kuba2k2]

It can be supported, don't give up yet.

Apparently this bootloader could be locking readout from 0x0.

Try using bk7231tools to read the flash chip contents:
https://github.com/tuya-cloudcutter/bk7231tools

bk7231tools read_flash -d COM11 -s 0x11000 -l 0x200000 dump.bin

[I-hate-2FA]

[kuba2k2]

Right, so it seems it detects the flash size correctly.
Try with -s 0x0.

dump.bin.txt
it seems to work, i used a brand new chip for this, cuz idk if delid have damaged it

[kuba2k2]

Just curious, where did you find these BK7231S chips? We've never seen this particular model before, are these available to buy somewhere as bare chips?

i bought 15 smart bulb for $4, it have this chip,isolated mains driver, pwm controlled RGBCCT

[I-hate-2FA]

[I-hate-2FA]

is there any chance for this to work

[kuba2k2]

Yes. You can probably just flash ESPHome, provided that you use this in your YAML:

esphome:
  name: my-device-name
  platformio_options:
    board_build.bkcrypt_coeffs: 00000000000000000000000000000000
    board_build.bkota.key: 0123456789ABCDEF0123456789ABCDEF
    board_build.bkota.iv: 0123456789ABCDEF
    board_flash.calibration: 0x1F3000+0x1000

Note that the bootloader on this device is the oldest we've seen, it looks very much different from all the standard bootloaders.
Because of this, I'm not sure if this device will support OTA as-is.

After compiling ESPHome, try flashing the image_bk7231t_app.0x011000.rbl file from the build directory to offset 0x11000, using the tool that works for you.

As long as you don't flash anywhere in between 0x0 and 0x11000, you should be fine.

[I-hate-2FA]

what cpu should i select in esphome
is board: generic-bk7231n-qfn32-tuya correct

[kuba2k2]

You should use generic-bk7231t-qfn32-tuya, not the N variant. T is the closest to your chip.

[I-hate-2FA]

it cannot compile
