Hello,
I just compiled U-Boot v2020.04 for a PINE64 Rock media board. It compiles fine without errors, but when I try to probe the on board flash I get an error:
=> sf probe Invalid bus 0 (err=-19) Failed to initialize SPI flash at 0:0 (error -19) =>
SPI is activated in the Device-Tree blob. I also added support to the Rockchip SPI driver (added IDS strings for this SoC).
In the device config I added the following:
CONFIG_SPI=y CONFIG_ROCKCHIP_SPI=y CONFIG_SPI_FLASH=y
But the driver still doesn't work. Output of DM (shortened):
=> dm tree [...] spi 0 [ ] rockchip_spi |-- spi@ff190000
spi_flash 0 [ ] spi_flash_std | `-- spiflash@0 [...]
What is missing? Is there a way to load driver?
Any kind of help is highly appreciated.
