I could test successfully on RISC-V, booting from MMC on a command line shell, and testing i2c4. However, I have an issue with Ethernet. When I add "ip=172.24.0.2" (for example) to the kernel command line, I'm getting this: [    2.586984] stmmaceth 4070000.ethernet eth0: Register MEM_TYPE_PAGE_POOL RxQ-0 [    2.596428] stmmaceth 4070000.ethernet eth0: cannot attach to PHY (error: -ENODEV) [    2.627351] IP-Config: Failed to open eth0 [    2.631859] IP-Config: No network devices available However, "eth0" appears in the list of networking devices. Does this work on your side? Cheers Michael. -- Root Commit Embedded Linux Training and Consulting https://rootcommit.com
