Hi Chris, To use the 64 MiB of SDRAM on the RZA2MEVB development board, SW6-4 must be switched off, making the first Ethernet port unavailable. Fortunately RZA2MEVB has two Ethernet ports, so this patch series makes U-Boot fall back to using the second port instead. Note that this does not apply to upstream U-Boot, as the sh_eth driver has been reworked in upstream, and as upstream does not support RZA2MEVB yet. While this allows me to use TFTP, I still cannot boot my own non-XIP Linux kernel (uImage with LOADADDR=0x0c008000), as it seems to crash in the "blcs cache_on" in linux/arch/arm/boot/compressed/head.S. A similar kernel boots fine on RSK+RZA1. Thanks for your comments!
