Hi, I have a custom board based on the Rockchip evb-rv1103 (RV1103B silicon), booting from SPI-NAND.
I can successfully boot the vendor Rockchip U-Boot v2017.09 on this board, from SPI-NAND I am currently working on upstreaming U-Boot support for the RV1103B SoC. My first RFC attempt is available here: https://github.com/fabioestevam/u-boot/commits/rv1103/ Build steps: make evb-rv1103_defconfig make However, I am not yet able to boot U-Boot on the board. At the moment, the board does not boot and only prints "RKUART". My initial plan was to avoid SPL, similar to the evb-rv1108 approach (described in board/rockchip/evb_rv1108/README). Before going further, I would like to ask: Is the evb-rv1108 “no SPL” boot flow a valid reference for RV1103B? Any guidance or pointers would be greatly appreciated. Thanks, Fabio Estevam
