How to reset/change the network configuration without rewrinting the entire sd card. I've tries using the debug UART cable, but this lead to a Shell that doesn't allow any action on files. Thanks! ------------------------------------------------------------------------------------------ Split from Cannot connect to 192.168.200.1.

Can you please post the error message that appears when you try to do so? Best regards!

Press ESC in 1 seconds to skip startup.nsh, any other key to continue. Shell> Obviously the SD card is inserted and working. So after that a simple ls command doesn't work because of mapping problem. I'm facing for the first time with this shell, so I may miss some information on using it. Thanks for your help! Regards

Regards This information ("No SD card found") and the shell appear if the SD card isn't inserted correctly or the SD card does not contain an image. If you are sure that your card is inserted correctly I think you have to write the image on your SD card again. Best regards!
