Marek / Tom, I modified arch/arm/mach-omap2/omap3/Makefile with the above patch, and the U-Boot portion appears correctly now when I use an SPL that was compiled without LTO: U-Boot 2021.04-rc3-00277-ge47d3424df-dirty (Mar 04 2021 - 16:09:09 -0600) OMAP3630/3730-GP ES1.2, CPU-OPP2, L3-200MHz, Max CPU Clock 1 GHz Model: LogicPD Zoom DM3730 Torpedo + Wireless Development Kit Logic DM37x/OMAP35x reference board + LPDDR/NAND DRAM: 256 MiB NAND: 512 MiB MMC: OMAP SD/MMC: 0 Loading Environment from NAND... OK OMAP die ID: 619e00029ff800000168300f1502501f Net: eth0: ethernet@08000000 Hit any key to stop autoboot: 0 OMAP Logic # Unfortunately, the SPL portion doesn't boot when compiled with SPL, but I think we're getting closer. Unfortunately, I don't have a good debugger to use and without any serial port output, it may be difficult for me to debug.
