support for BK7231M(CB2S) #262
Comments
|
Well, that certainly is an oddity. That firmware is unencrypted, and appears to have the BK7231N 1.0.11 bootloader, and doesn't have Tuya firmware, but some other 3rd party. I'm not sure if the I'm guessing this would already work with a custom coeff for unencrypted, but I'm unsure what that looks like (and the corresponding ota key/iv and possible ota offset), so I'll leave that to @kuba2k2 to advise on. |

This device indeed appears to be unencrypted. ESPHome config for this device: esphome:

How did you flash the firmware, and what file did you flash? Please connect UART to TX2 and capture log outputs from the device. Otherwise we can't even tell if it's running or not. |

@kuba2k2 I try to flash the bk7231m by using many ways, same result: no wifi,no ap,no uart log bk_misc_init_start_type 0 0

I didn't mean UART log of the stock firmware, it's not useful. If it's not Tuya, it's not unusual that it doesn't use AP mode to connect. We need UART logs after flashing either the UF2 file by ltchiptool or the RBL file by bkflasher. So, choose either of these methods (one that works), flash the file, then dump the flash again. Attach here the UART log after flashing and the resulting dump file after flashing. |

@kuba2k2 no uart log by normal flash the uf2 or rbl . So I did some hex trick on the dumped flash bin file (pre-flashed with uf2), I copy the stock firmware bin [0x0~ 0x00011115] to the dumped uf2[0x0 ~ 0x00011115] , and then flash the modified uf2 bin file into bk7231m by bkflasher ,It actually started running!!!!! The hex area is bootloader?? log: �[1;32mI [ 0.000] �[0mLibreTiny v1.4.1 on generic-bk7231n-qfn32-tuya, compiled at Mar 8 2024 21:48:43, GCC 10.3.1 (-O1)

Interesting, the UF2 file doesn't modify the bootloader area. Have you been flashing OpenBeken QIO binary in the meantime? The QIO contains an encrypted bootloader, which will not work on your device and will prevent any firmware from running, unless you reflash the stock bin file. Also, can you attach a screenshot of "Read chip info" from ltchiptool? This might help troubleshoot the CRC errors you were getting. |
OpenBeken QIO binary do not work,same as uf2 binary, no wifi/no ap/no uart log I use ltchiptool to flash back to stock firmware(ps:the name of stockfirmware in the picture has been renamed,it is not the OpenBeken QIO binary) ,it tell me the chip is Realtek.... so I can only use bkflasher to flash stock firmware. I'm not sure if those hex tricks have bugs, because I saw some errors from the esphome logs,like: �[0;35m[C][wifi:411]: IP Address: 0.0.0.0�[0m

|
You should be able to flash the .bin file by ltchiptool if you uncheck the "auto detect" box and clear the start address, skip offset and writing length boxes. Also set the chip family to BK72xx. That being said, because your chip is unrecognized, it will fail all CRC checks because BK7231N does this differently. There is a pending update of bk7231tools that addresses this issue. |
I just use ltchiptool to flash back to stock firmware ,process 100%,get crc error,but the stock firmware can work normally.May be the way of crc different between ltchiptool and bkflasher,this stock firmware was dumped by bkflasher, I think this crc error does not matter. |
|
@kuba2k2 After re-flashed a new device with bk7231m, I think my previous description about flashing was wrong. |
|
In step 2, where you flashed OpenBeken QIO - that's the mistake. OpenBeken's files currently will not work with your device. Doing that, you overwrite the bootloader (0x0-0x11000) with the wrong one, which makes your device fail to boot. ad. 7.: your device might be using a different RF partition address. BkFlasher's "Restore RF" function might indeed generate a random MAC address, however it will NOT write the correct Wi-Fi calibration data. You might get reduced Wi-Fi range and/or performance, or other issues. The correct solution would be to update ESPHome/LibreTiny's partition layout: esphome:
name: my-device
platformio_options:
board_build.bkcrypt_coeffs: 00000000000000000000000000000000
board_build.bkota.key: 0123456789ABCDEF0123456789ABCDEF
board_build.bkota.iv: 0123456789ABCDEF
board_flash.download: "0x132000+0xA6000"
board_flash.kvs: "0x1D8000+0x8000"
board_flash.calibration: "0x1E0000+0x1000"
board_flash.tlv: "0x1E1000+0x1000"
board_flash.net: "0x1E2000+0x1000"
board_flash.userdata: "0x1E3000+0x1D000"(taken from BK7231T default partition layout, offsets match your device) If that doesn't work, restore the stock firmware and try again. |
|
@kuba2k2 Should I modify the board_flash.app? I found there are some data before 0x132000 in the stock firmware binary file.
|
|
No, this is part of the app partition. This is the RBL header, it's not even important for running the app. You don't need to change the app partition. |
|
@kuba2k2 it always get a CRC error when flash the uf2 file with ltchiptool, so I copy all data of bk7231m-1-0x011000.rbl to the stock firmware(2M),and then flash this new 2Mb file to the bk7231m.

@shzlww are you able to test this BK7231M with the latest version of ltchiptool? In particular, I'm curious if the flashing succeeds now, as well as the "Chip ID" from "Read chip info". I'd appreciate a screenshot of the chip info dialog. |

The pcb design in the photo looks very much like the Arlec PC191HA Series 2 Smart plug with energy monitoring, which is sold by Bunnings in Australia (yours I am guessing is probably a different brand etc, and the Arlec ones have tuya on them, however...). Your board layout looks familiar, plus the symptoms of flashing are also similar, in that folks with the PC191HA plugs often find that the flashing appears to go through OK, but then the device still boots up with the old firmware. This is happening even after the initial flash to esphome/libretiny using cloudcutter, and on subsequent OTA flashes. What someone else discovered and I've found works reliably is that after successfully flashing, you need to remove power from the device, then hold down the button while applying power again (then releasing). This seems to cause the unit to take a while longer to boot, during which time it appears to apply the new firmware image. I don't know if perhaps it's keeping separate firmware partitions or something, but it seems that without the button held down during power-on it's quite random as to whether the new firmware just flashed will "stick". I don't know if this will actually relate to your issues since your device is definitely different in some ways, but given the board layout similarity it might be worth trying that procedure to see if it improves things for you. |

Describe the bug
I have a smart plug(not Tuya version) with cb2s module ,but the module is using a BK7231M.
I try to flash it with ltchiptool,but i get CRC error at 28%, never success,then I try to flash it with bk7231flasher of OpenBeken, When selecting BK7231N, the Module would flash just fine, but when power cycling it, it would not boot and the AP would not come up.
So, Could BK7231M be support by libretiny?
