Description
In the Arria® 10 U-Boot bootloader in SoC EDS version 15.1.2 and earlier, there is a NOC timeout that is erroneously left enabled by the reset_assert_all_bridges function. This timeout can be reached if IP in the FPGA is slow to respond, resulting in an access error.
Resolution
This problem is scheduled to be fixed in the next release of SOC EDS. There is a patch available to address this issue with previous releases here: https://github.com/altera-opensource/u-boot-socfpga
