At present the AE350 SPL defconfig is using OF_PRIOR_STAGE. The intention was to use gdb to load device tree before running U-Boot SPL/proper from RAM. When we switch to OF_SEPARATE we will have to use our own DT but without "u-boot,dm-spl" in several essential nodes, SPL does not boot.
Can you describe how do you verify and provide the steps about that SPL boot fail that I can duplicate it. :)
$ make ae350_rv64_spl_defconfig; make -j $ make menuconfig (change OF_PRIOR_STAGE to OF_EMBED or OF_SEPARATE)
Load u-boot.bin to RAM
It can boot with OF_EMBED. But it compile fail with choosing OF_EMBED at the first time, fail messages as below:
binman: [Errno 2] No such file or directory: 'u-boot.dtb' Makefile:1084: recipe for target 'all' failed make: *** [all] Error 1
Yes, this is a known issue of the binman conversion for SPL. OF_EMBED is a debugging purpose hence I am inclined to leave it as is.
