Hi Macpaul,
The size of device tree node secmon (bl31_secmon_reserved) was incorrect. It should be increased to 2MiB (0x200000).
192K should work when the patch(6147314aeedc) was accepted. Does the trusted-firmware-a get larger now, so we need to increase the size to 2MiB?
thanks, Miles
The origin setting will cause some abnormal behavior due to trusted-firmware-a and related firmware didn't load correctly. The incorrect behavior may vary because of different software stacks. For example, it will cause build error in some Yocto project because it will check if there was enough memory to load trusted-firmware-a to the reserved memory.
