I have applied the patch from FUKAUMI, and now my console output has started working > 1. Make u-boot-rockchip.bin with "audio-supply = <&vcc_3v0>;" > 2. Write it to microSD card > 3. Insert it > 4.

Try "sf probe" "sf erase" > Yes, I have tried these steps (4 Kill SPI flash) -> I have shortened the SPI1_CLK and GNG in the GPIO header But this board first boots from SPI flash, I don't know the reason. I noticed your patch references the W25Q128. Did you get this device detection in userspace? This output is from your patch. => led blue:status off => sf probe SF: Detected w25q128 with page size 256 Bytes, erase size 4 KiB, total 16 MiB => led blue:status on => sf probe jedec_spi_nor flash@0: unrecognized JEDEC id bytes: ff, ff, ff Failed to initialize SPI flash at 1:0 (error -2) Could this explain why I’m unable to detect the device from userspace? > Best regards, > > -- > FUKAUMI Naoki > Radxa Computer (Shenzhen) Co., Ltd. > Thanks -Anand
