Dear reader,
For my master thesis in Electrical Engineering I am working on providing OpenWRT support for pynqz2 and adrv9361 boards (armv7 32bit). OpenWRT uses U-Boot 2019.07.
In the default config file (that I partly had to add stuff/remove stuff myself, see attachment zynq_pynqz2_defconfig), the CONFIG_SPL_OS_BOOT setting is set to yes. This failed during boot, the boot image is a FIT image.
Booting via load+bootm works (see attachment boot_commands.txt and load_bootm_log.txt).
If I understand it correctly, this is a SIMPLE_FIT?
I have been trying to get the SPL to boot the kernel for a few days now. It seems to be stuck on the gunzip function (see attachment SPL_log.txt)
Does anybody has a clue to what is going on here? Documentation and more about SPL booting kernel and FIT images are always welcome.
Kind regards,
