I tried to boot the debian from SD with the Method 2 (maskrom 3s) but the led SYS stayed red without any boot from the system.
Could you please give me more information how to boot from SD Card ?
I also tired ubuntu image with the same result... Do you have a idea about my issue ?
My sd is a SanDisk 128GB TF MicroSD U3 C10 A1 V30 4K.
Thanks in advance for your help.
