spi1 = &spi1;I don't really understand why but this added alias break spi flash detection on rockpro64. Removing it make it work again.
I've noticed the same problem - rockpro64 already had an alias
spi0 = &spi1;
so after this change there are spi0 and spi1 aliases pointing to &spi1. In U-Boot proper, that seems to cause the SPI flash to appear on bus 1 rather than the former bus 0, e.g. sf probe 1:0 works but sf probe 0:0 doesn't.
So I tried removing the spi0 alias and setting CONFIG_SF_DEFAULT_BUS=1 which fixed the flash detection in U-Boot proper, but now the SPL can't load U-Boot from SPI flash - it fails with an "Invalid bus 1 (err=-19)" It seems like SPL doesn't pay attention to the spi1 alias in the same way that U-boot proper does, I haven't yet figured out why.
Could this be CONFIG_SPL_DM_SEQ_ALIAS ?
Regards, Simon
I don't know if you suggested to set CONFIG_SPL_DM_SEQ_ALIAS=y in configs/rockpro64-rk3399_defconfig but this doesn't help.
Cheers,
