I used the latest kflash_gui 1.5.3, and 1.5.5 in linux. Both othe tool could not communicate with the k210 board.
Maixpy IDE is able to connect with the board and download the python script and debug.
1.5.5 will try for a while and report the greeting failure. the console will output
The latest is v1.3.2, now:V1.5.5
In the windows, the download is OK.
Is there any suggestion on how to make kflash_gui working in Linux?
