Hi, I am trying to make Friendlyelec NanoPi M5 (RK3576) work with mainline. I found the note about needing a workaround so have tried kwiboo/rk3576 at
https://github.com/Kwiboo/u-boot-rockchip.git I am building like this: $ ROCKCHIP_TPL=~/dev/rkbin/bin/rk35/rk3576_ddr_lp4_2112MHz_lp5_2736MHz_v1.09.bin BL31=~/dev/rkbin/bin/rk35/rk3576_bl31_v1.20.elf um build nanopi-m5-rk3576 Image 'simple-bin' is missing optional external blobs but is still functional: tee-os /binman/simple-bin/fit/images/@tee-SEQ/tee-os (tee-os): See the documentation for your board. You may need to build Open Portable Trusted Execution Environment (OP-TEE) and build with TEE=/path/to/tee.bin Image 'simple-bin-spi' is missing optional external blobs but is still functional: tee-os /binman/simple-bin-spi/fit/images/@tee-SEQ/tee-os (tee-os): See the documentation for your board. You may need to build Open Portable Trusted Execution Environment (OP-TEE) and build with TEE=/path/to/tee.bin $ dd if=/tmp/b/nanopi-m5-rk3576/u-boot-rockchip.bin of=/dev/sda seek=64 18579+0 records in 18579+0 records out 9512448 bytes (9.5 MB, 9.1 MiB) copied, 1.99658 s, 4.8 MB/s I get no serial output at all booting from SD card. Is there a special trick I am missing? I have confirmed that the Alpine Linux image works OK. Thanks, Simon
