TZC permission failure ... AXI ID 4a0

[Every]

My MP157DAC board encountered some problems using SDKv5.0, u-boot could not be started correctly when using usb burning, it seems to be related to DDR, but I can not find the reason, the community does not have similar problems, hope to get some help:

 

DRAM: E/TC:0 tzc_it_handler:79 TZC permission failure
E/TC:0 dump_fail_filter:417 Overrun violation on filter 0
E/TC:0 dump_fail_filter:420 Permission violation on filter 0
E/TC:0 dump_fail_filter:425 Violation @0xfdb16fb0, non-secure privileged read, AXI ID 4a0

Looks like it's a ddr problem.
