Meta/lib/oeqa/selftest/cases/fitimage.py | 293 A patch adding this tool to U-Boot has been accepted together with the first one. Meta/classes/kernel-fitimage.bbclass | 69 +++. I added oe-selftest testcases and also tested this on upstream OpenBMC Since the configuration may determine which PN does that. Might need to remove the tmp/ directory, since there could be aĬollision for some of the files deployed into the images directory, One caveat is that when moving between the scenarios above, the user We need to also sign the FDT image containing the Kernel pubkey), and PN will take care of creating and signing the U-Boot fitImage (becase In case both UBOOT_SIGN_ENABLE and SPL_SIGN_ENABLE are set, the Kernel ![]() U-boot-spl-nodtb.bin to create the final U-Boot SPl on deploy.

This means that ROM code is the first thing to load (and execute) other programs, and SPL is the second thing to load (and execute) other programs. It should be noted that SPL stands for secondary program loader. So this first stage boot loader is U-Boot SPL and the second stage boot loader is regular U-Boot (or U-Boot as appropriate). This additional bootloader is usually called the first-stage bootloader (in the two-stage bootloader scheme). Therefore, we need to create some additional bootloaders, which will initialize the regular RAM and copy the regular bootloader from the MMC to the RAM, and then will jump to execute the regular bootloader. Usually, regular bootloader (such as U-Boot) binary files are larger than this value. SRAMMemory is limited (for physical reasons), so we only have 48 KiB for the bootloader.
