Unable to read/write ZynqMP PS CSU Multiboot reg in U-Boot using MMIO API
I'm using 2018.2 SDK, and want to reset CSU Multiboot register in U-Boot when doing QSPI_MODE boot.
I first tried using zynqmp_mmio_write(), but it didn't seem to reset the register in my testing. The boot.bin flashed at a higher address continued to boot on warm resets. Doing a PoR resets the register as expected however.
