I would expect that after [1] was merged in v2024.07-rc1 the likelihood
of booting a bad/poor flash (where FIT checksum is invalid) have been
mitigated and the boot process now fall back to loading FIT from SD-card?
Or is it to protect against flashing a FIT containing a non working
U-Boot proper that this tries to protect against?
Also sdmmc1 seem to be missing from SPL control FDT so that could also
impact fallback logic in SPL. Following nodes should be added to
rk3566-anbernic-rgxx3-u-boot.dtsi:
&sdmmc1 {
bootph-pre-ram;
bootph-some-ram;
};
&sdmmc1_bus4 {
bootph-pre-ram;
bootph-some-ram;
};
&sdmmc1_clk {
bootph-pre-ram;
bootph-some-ram;
};
&sdmmc1_cmd {
bootph-pre-ram;
bootph-some-ram;
};
&sdmmc1_det {
bootph-pre-ram;
bootph-some-ram;
};
