New Windows Progamming tool - openshwprojects / BK7231GUIFlashTool

First of all, thank you so much for your hard work on the BK7231-devices. Openbeken works just great. I have bought a couple on aliexpress for 2$ each from promotion offer. The tiny devices are BK7231N types on CB2S Modules with 16A relais. I will post a teardown-instruktion later. After desoldering one device with small damages I succeeded in programming with python uartprogramm. Soldering back and the device worked flawlessly. With another module I tried the new flashtool. It worked great while reading but it stopped before writing saying something like "baudrate failure". I tried all options but neither worked for me. Going back to the python script everything worked just fine. So I am lucky to have a valid copy of the original firmware. Do other users encounter similar problems or did I miss something? Thanx again and happy new hacking year to all of you.

Hello, which baudrate setting did you use?
Have you tried lower baudrate speed?
Can you post full log?

If reading part of "Read backup and flash firmware" works ok but then it fails with baudrate, then maybe you should do separate Read operation and then a Write?

You can always fall back to uartprogram from hid_download_py if the problem persists.

Thanks for your quick reply
I tried all available baudrates (all three in the dropdown menu).
Separate reading worked as expected but separate writing button didn't respond.
As mentioned uartprogram worked after that at 115200. So module is working fine.
Go on with your excellent work please.

What do you mean by "didn't respond"?

I will try to check on my side, but so far all my tests were successful.

I mean the button was not working.
I have another module and will try again.
I come back to you after that.
Thanks

You are right, I forget to link an action to the button. Write button will be fixed in about a hour

Thank you but read/write is still not working for me...

Erhard

What if you do separately Read and then separate Write?

Will give it a try and come back to you...

It seems that I've found the bug.
Or at least one bug. It seems that on some machines the larger UART buffer was required:

It's fixed in v1.0.3

The default one is 4096 so it makes sense that a page read that is 4096 bytes + header won't fit, but I didn't caught it earlier on my machine because.... it just worked well for me.
No idea how Serial class internals are handling that, so it actually worked for me all the time without setting a big enough buffer.

Thank you for your effort.
Every time I start my computer I learn something new - helps to keep me young.

May I suggest to put a button 'Main Menu' on top of the list in the web interface of openbeken rather than a tiny link underneath the long menu strip?

Now the flashtool works perfectly.
Thank you, Donation is on its way.
Have a nice weekend.
