I have been running an application on the Zynq processor for months with the correct configuration. I went to rerun my code and received the error "memory write error at 0x70000000. cannot read sctlr. cannot read r1. APB memory access port is disabled." I fixed this error at the very beginning when working with this board because it was a configuration issue on the DDR. The PS configuration has not changed, and I cannot even go back to a hello world template to work. I tried the DDR memory test too and that didn't run. It seems like the FSBL is not completing. Any ideas?

In FSBL, there is a function that prints XFSBL_PSU_INIT_FAILED, so by looking at the FSBL source code, you can track where the error is occurring.
