My board with stm32mp157 wakes up from CSTOP with UART wake source, but cannot wakes with RTC or WAKEUP PINs from STANDBY. TF-A outputs strange errors at the end:
ERROR: Illegal access to 0xe0000000 in :
And nothing goes on until watchdog reset.
This lines I see in tzc400 sources. But I don`t know how to interpret this.
Could anyone explain what is going wrong when I`m trying wakes from STANDBY?
Hi AKudr.1 (Community Member)
It seems that the DDR firewall is not correctly setup.
Normally we use for a 1Gb DDR
memory-ranges = <
0xc0000000 0x20000000 TZC_REGION_S_NONE TZC_REGION_NSEC_ALL_ACCESS_RDWR>;
Are you using DDR addresses above this region?
