Maixduino no longer connecting to Maixpy IDE

[Martin-Biomed]

Hi all,
I have a problem in which I tried to upload a new .kmodel into the Maixduino (it seems to have been successful). But now it seems Maixpy IDE never connects to my board anymore.

I tried a full chip erase on kflash_gui, and re-uploaded the .kmodel. Again, no connection with Maixpy. I really want to know how to fix this, otherwise there's nothing I can d with this board.

Current version of firmware: maixpy_v0.5.0_125_gd4bdb25
Current version of Maixpy IDE: 0.2.5

Reflash the original firmware starting address 0x00000, that will do the trick

Hi all, I have the same problem after trying to flash a kmodel. The problem is that kflash does respond that it cannot find a k210.
Port is available but no upload possible. I recognized that the RX-LED does not blink anymore. Only TX is blinking. The both ESP-LED's are working properly. Hope someone will find a solution otherwise the board is not more usable!
