Is that correct? PMUFW needs to be loaded and can be built from SDK/VITIS or taken from petalinux. bl31 is ATF - also you can build it or take it externally. > > If it is, then there are only two components that can be wrong: u-boot > SPL and ATF (bl31.bin), am I right? > > Also, I assume that bl31.bin is incorporated into spl/boot.bin, so I > don't need to supply it externally, is that so? ATF is not the part of boot.bin. PMUFW is the part of boot.bin. > > Don't get me wrong, I already tested loads of configurations with > various incarnations of PMUFW and configuration object, etc., and never > ever have I seen the "U-Boot SPL" welcome message on the UART.
