U-boot Updates
#2
>I would like to run the latest U-boot........why?
All uboot does is set up mem to safe state, set up serial com, scan media, load cfg file, load kernel
Some, maybe 3 uboots drive display
If you install to SPI (which I do not recommend) be aware it is different than SD/emmc uboot
there are probably more than 10 uboots out there, all doing more or less the same thing
The main differences are BSP,, mainline,, drives display
BSP are 3 files, mainline 2 files,,u-boot.itb = uboot.img + trust.img
Getting, well google and other searches, make SURE that it is specifically for pbp or maybe any rk3399
My emmc has only mbr in 1st 16M, uboot with distro on SD OR uboot alone on SD
save mbr, save 1st 16M, blank 1st 16M, restore mbr (all on emmc),,,,, all with dd & count
With uboot alone, make a FS on the rest of SD or uboot will lock, maybe the error recovery is better in later versions
