Hello,
I have a custom imx8qm board
The BSP setup:
U-Boot 2019.04
ARM-TF imx_5.4.24_2.1.0
linux-imx 5.4
OP-TEE 3.10
I am trying to add OP-TEE to the board.
I have an issue with the rebooting the board.
After debugging it turned out that after calling sc_pm_reboot in ARM-TF
https://github.com/boundarydevices/imx-atf/blob/boundary-imx_5.4.24_2.1.0/plat/imx/common/imx8_psci....
the board does not bring up.
1. What could be the reasons the board does not reboot?
2. How to debug the issue?
3. Is it Ok to use sc_pm_reset instead of sc_pm_reboot
in the setup With OP-TEE?
https://github.com/boundarydevices/imx-atf/commit/c8c1085323219563401454be45a56b53c8a41d47
4. What I am missing to make sc_pm_reboot reset the board?
Without adding the OP-TEE the board reboots as expected.
The Debug Monitor read power mode after reboot command shows the following output:
>$ power.r
