I'm prototyping a system using the MicroZed board. The intended target board has QSPI Flash that is expected to be mostly consumed by the FSBL, PL bitstream, and U-Boot, so the Linux boot files need to be in eMMC flash. The eMMC flash will also be soldered to the target board, so no opportunity to load the Linux files other than through U-Boot. My MicroZed prototype boots Linux from the SD, but if I load U-Boot from QSPI, then load/boot the same Linux files from the SD image, the boot hangs partway through. Any ideas? Thanks.
