Hello,

BK7231N (CB3S) chip I can't do flasch or backup. Whichever I do.

In the HID Download itself goes without the slightest problem.

Thanks, will you be able to recheck if I give you updated flasher binary?

Yes, i can check this. First afternoon 😉

The wb3s device also has a reading problem. The recording goes smoothly.

Does the problem happen only in "Backup and write" modes or in a separate modes as well?

I will try to prepare a build with increased time for read operation and we will see what happens.

In my case both during backup and write. Also the write and read test in the advanced options do not allow to communicate properly with the MCU.

It works for me... I increased a delay in UART read for slower computers... Can you recheck? https://github.com/openshwprojects/BK7231GUIFlashTool/releases/tag/v1.0.2

1.0.2 doesn't give the countdown to do the reset

No @itsj4y , it's not the version thing. You won't get countdown to RESET if you do erase flash memory of BK but do not write. This is because in this case BK has no application and reboots constantly.

The same will happen in bkWriter or anything, as long as you do erase without write on BK.

Still... thanks for testing. I hoped that increasing the delay from 5 to 10 seconds will help, but it seems that issue is somewhere else.

Flash respond command is the following: byte[] cBuf = new byte[] { 0x04, 0x0e, 0xff, 0x01, 0xe0, 0xfc, 0xf4, (1 + 1 + (4 + 4 1024)) & 0xff, ((1 + 1 + (4 + 4 1024)) >> 8) & 0xff, (byte)CommandCode.FlashRead4K};

so your buffer content looks like it has a start of flash read command, but for some reasons it's cut in place?

Can you try different baud rate, like 128000 and 256000 ? You can enter those numbers into the field (copy paste them, they are not on the list).

Extra question: can you show a photo of your USB to uart converter and/or give me a specific model name of it?

Ok so it worked after firmware write (no backup)

I have added a larger buffer, it was not needed for my machine, but maybe... That 4096 seems suspicious, because it fails somewhere around that point, but again.... for some reasons it always work for me. Still, it's worthchecking. Can you all check this release, please? https://github.com/openshwprojects/BK7231GUIFlashTool/releases/tag/v1.0.3

This was successfully done. You made it :) With https://github.com/openshwprojects/BK7231GUIFlashTool/releases/tag/v1.0.3 works for me.

Thank you @Rafik89 for testing. It's a good news. I am still super surprised that it worked for me with 4096 buffer, it's very strange. Still, I would like everyone else here to test it as well, because I am not yet sure that it's really solved.

I checked WB3S reading, everything works. I will try to restore the original firmware of the device. I will help you test Flasher mode: BK7231T Going to open port: COM6. Serial port open!

Do not try to restore the original firmware without me adding an option for that first! You may break your bootloader.

Hello, I have problem flashing CB2S. I'm using ftdi ft232rl and external power suplier. I tried all baudrates mentioned here and problem was allways same:

@veivari which version?

@openshwprojects 1.0.3

Hi @openshwprojects, I'm facing the same issue as @veivari but using version 1.0.4 I tried a couple of baudrates but no success. Using CH340 as USB to TTL guess it's from AZ Delivey.

Edit:

tried using windows (and BK Writer): looks the same

I also get the same problem:

Failed!

I'm using this USB to UART device: https://image.made-in-china.com/2f0j00levUBmHLfGos/FT232r-USB-Uart-Nano.jpg

Edit: What i recognized is that... Sometimes the blue LED of the the tuya device is not on nor blinking. Then i'm not able to get the bus. So i press the device button and the blue led starts blinking. Then i can do the CEN reset and the tool starts to read data.

But after a few seconds the reading failed. Interesting is, that the blue led is off. It looks like the device is turning off while reading data.

Edit 2: I don't know if it's interesting, but on the chip is labeled with "CB3S" (not CB2S)

@dawosch isn't it a battery-powered device where MCU turns off the wifi module? Can you show device photo?

@Rafik89 Yes it is. Ignore the wirering. I tested a lot. My approaches based on the connection direct of the chip.

On the other side there is the battery mount.

Sorry but your problem is not related to the flasher. Basically, this device has TuyaMCU and TuyaMCU might interfere with flashing. You can either cut the rx/tx tracks or desolder the MCU temporarily. You can read and ask more here: https://www.elektroda.com/rtvforum/topic3914412.html

Ok, thanks for the info. But one more question/idea. At the current highest baud rate i can read or write round about 80% of the firmware before it interrupts.

Would it be possible to increase the baud rate a little bit more to write the firmware complete? Or reduce the firmware size for faster writing?

Thanks

If you are asking in relation to TuyaMCU devices, then it's not practical. The correct approach is just to power the device correctly (avoid MCU interruption) and, if required, remove temporarily the MCU or cut traces.

I have the same issue with BK7231N - it's from a smart plug, so I don't think there is the mentioned above TuyaMCU on board (attaching pictures just in case I can't see it). I have tried different baudrates I'm using 1.0.4 version of the flasher Here are my logs: Test read/write pattern

Hello,

iam having an problem with an BK7231N on an aliexpress relay board.

Firmware read was a success at first, the write is the problem (thats the reason why i dont do a backup in this try) it randomly stops either at 0x4000 or 0x1000. At higher baudrate there was no connectivity at all 115200 did following.

TTL chip/board used is an cp2102*

Hi Dexruus,

did you try to modify the timeout as I said in my previous message ?

Hi, just wanted to add that I'm basically having the same problem. I've tried increasing the timeout to no success. I compiled the GUI under Linux, it seems that might make a difference. I also switched baud rate down to 115200. I then used the old python programmer which had no issues writing the chip. So something is different in the way Mono reads and writes to the serial port compared to the python script. This was for a BK7231T chip.

This is more an FYI that this is still an issue for at least some users. I'd love to see it working, since the GUI is much nicer and easier to use than the python implementation.

I don't know what is wrong. It seems to work reliable for me. @thinksilicon how did you compile it on linux?

Btw, I have a major update coming for this tool. It will be possible to extract Tuya config very easily and also it will be possible to configure OBK in place, from the flasher access. It will be released in few days.

Hey, I built it with xbuild, which did give a deprecation warning, but still built fine. Reading code didn't succeed at all. It did make a connection to the bus after I toggled CEN, however it did not read any bytes. Writing started with erasing like the previous posts in this issue and then errored out at various times during the erase. Maybe it's just some oddity with Mono + serial ports under Linux.

Hey, just wanted to say that I was having a similar issue on linux but it worked fine on windows. As you said, it probably has to do with the interaction with serial ports over Mono. Hopefully they can find a fix!

It works for me... I increased a delay in UART read for slower computers... Can you recheck? https://github.com/openshwprojects/BK7231GUIFlashTool/releases/tag/v1.0.2

Great! Thanks for this hint! =) Increasing UART timeouts worked for me too (Set to 5 first and second). Tried in Linux (Ubuntu) ARM on Parallels VM on Mac M1. Ubuntu 22 04 ARM64 2023-07-01 01-08-04

Thanks, this helped. No issues on my Windows 10 laptop. But on my Ubuntu 22.04 workstation (Ryzen 5700G) I faced the same issue. By changing two of the topmost UART timings from 1s to 5s everything started working.

Thank you for testing. Now 5s delays in those two fields are default values. I've made a release - BK7231 GUI Flash Tool 1.1.1

with a separated CB2S module, I got the sequence

SetProtectState(True) success!
Going to start reading at offset 0x00...
Reading 0x00... failed with serial.BytesToRead 4095 (expected 4111)
The beginning of buffer in UART contains 040EFF01E0FCF4061009000000200069 data.
Failed! There was no result to save.

on a Debian "testing" system on a Ryzen 5 4650G with version 1.1.1 (so with the two defaults of 5, I checked them). With 9 sec in both entries it only waits longer after the Going to start reading at offset 0x00... line.

No problem on a Windows laptop with the same hardware. My serial adapter is nearly exactly the same like the one above.

May be the higher timeout wasn't the reason it worked but only increased the chances.

Might relates to #19

I had the same problem on Arch Linux. Write was working fine, but it stopped at the backup. failed with serial.BytesToRead 4095 (expected 4111) It might worth a try to use this: https://github.com/OpenBekenIOT/hid_download_py Best regards
