I suffered a failure during an upload with Visual Studio Code. Since nothing worked as before after the failure, I finally decided for a "Full chip erase" with STM32 ST-LINK Utility.
After erasing, I successfully flashed the bootloader with "OpenRTK330L_Bootloader_v1.1.1.bin" as documented in the tutorials. Unfortunately I am now stuck here! As also suggested by the tutorials, I created an emergency backup of the shipped image. Obviously I must have done something wrong since my emergency backup is not flashing with the comment "File size bigger than the flash memory size".
is there a way to flash one of the default firmware (e.g. OpenRTK330L_GNSS_RTK_INS_v23.01.bin) to the EVK? If yes, how to accomplish that?
Currently I face the green LED on the EVK flashing and I cannot communicate with the USB bus. I tried on Ubuntu 18.04 and Windows 10 with the python-openimu tool. Booth worked before the chip erase. Now the "--console-log" output repeats as shown below instead of connecting.
How to connect with USB.
