In our custom board which uses STM32MP153C, right when TF-A is about to launch u-boot it displays PSCI power domain map logs and MPU reboots with MPSYSRST reason. Any idea what is the root cause? We are using the device tree based on the dk2 sample device tree.

Hi @NBhat.1 ,
As per analysed by our local US office FAE :
USART1 was configured in secure mode in TFA. After changing its entry in TF-A DT to NS, U-boot worked fine.
TFA DT change:
-DECPROT(STM32MP1_ETZPC_USART1_ID, DECPROT_S_RW, DECPROT_UNLOCK)
+DECPROT(STM32MP1_ETZPC_USART1_ID, DECPROT_NS_RW, DECPROT_UNLOCK)

Hello,
I have run into the same issue with the latest ST Ecosystem 4.0.2 and I am not sure how to fix the flash loop.
My project is using the SiP from OctavoSystems (OSD32MP157c) and the DTS files are generated by STM32CubeMX 6.6.1. I have tried to set the USART1 in unprotected mode but it did not help. Can you please suggest to me what could cause this issue?
Bellow is flash log

Hi @Tom�? Ju?ena
Please open a new post with complete context ( eg was it working on previous ecosystem )
Also for OSD32MP157c I can advise you first trying to contact Octavo if they have pushed a DV4.0 sample image and/or MX6.6.1 ioc which can be used as reference.
Thanks,
Olivier
