Device bricked - no WIFI communication #227

Closed beaune33 closed 2 years ago

beaune33 commented 2 years ago

I had a LSC Smart Mood Light (3004154) working with firmware 1.12.61, which I flashed with hid_download.py successfully. Afterwards I tried an OTA update to 1.12.62, and probably I did something wrong. The device did not appear with an Openbeken AP, even after several tries to activate safe mode. To fix it I tried again to flash diferent firmware versions by wire with hid_download.py. Flashing works, but unfortunately still no WIFI appears.

Does anybody have an idea what I could do to unbrick my device? It is BK7231N based.

openshwprojects commented 2 years ago

Are you able to provide the log from TX2 so we know what happens?

beaune33 commented 2 years ago

I could try...could you explain how to do that?

euro2 commented 2 years ago

Excuse me for highjacking the thread. But is there a safe mode? For example when WiFi credentials all wrong and it won't go back to AP mode?

How? (Without opening the device....)

openshwprojects commented 2 years ago

@euro2 five times power on and off will return to AP mode @beaune33 UART RX in 3.3V mode to TX2 pin from the board. Of course do not power device from mains at that time.

There is also a certain stability improvement for N platform in work, stay tuned.

euro2 commented 2 years ago

@openshwprojects any interval in seconds? Or does that not matter? i flashed one succesfully now(had AP while hooked up to rasp pi4, but once inserted back in socket case no go Ill try resetting that way.

beaune33 commented 2 years ago

This is what I was able to catch. Flashed is version 1.12.64. Does it help?

MCU detected undefine instruction. Which caused critical crash. Here helps only new flashing, OTA process caused somehow write error into flash. May be using BK_Writer and do complete flash erase in case written configuration is causing it.

beaune33 commented 2 years ago

I was not aware that Bkwriter could also help to deal with N-type. But could you give me a hint how to erase the complete flash? I only see the option to write a file.

valeklubomir commented 2 years ago

image Erase all chip flash not always works with program. I do steps marked 1, 2, 3. Normally it end with success. The I disable Erase all chip flash and open QIO file and press Program.

I did not find setting in 'hid_downloader_py' to do Erase All Chip FLash.

beaune33 commented 2 years ago

Ok that helped:

Thanks for your help!
