I try it with the latest STMicroelectronics OSS image.
I just change in U-Boot config to be aligned the expected SD-Card partionning
configs/stm32mp15_basic_defconfig:
-CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION=3
+CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION=5
But low power is not supported in this downstream config :-<
Use multi_v7_defconfig or some such ?
I got the error:

Please fix your kernel config and enable suspend to mem, I am sure that is not
difficult.
I check also with downstream (OpenSTLinux V4.0),
This is not relevant to this discussion.
and I can't reproduced the issue but we are using TF-A / OP-TEE / SCMI to
support all the low power modes.
And this low power support (in TF-A/ OP-TEE / Linux with SCMI) is not yet up
streamed.
PS: if you are not able to restart even after a RESET,
I assume something is wrong in the PMIC configuration
(for example in NVM or in initial regulator configuration)
so you have no power cycle on DDR during reset...
=> something is wrong in PMIC configuration in linux ?
Possibly, but then it is also something wrong on STM32MP157C EV1, because I can
reproduce the failure on EV1 too. I specifically did check this on the EV1.
Please fix your kernel config and try again, then you should be able to see it
yourself.
Has there been any news on this defect of EV1 or has this been ignored by ST ?
Hi Marek
Hi,
Sorry for the delay,
No worries.
What I am more concerned about is -- why is this problem present on EV1
too and how to solve it there ? (and no, "add more unnecessary software
to the stack to cover this up" is not the answer)
Patch applied on stm32-master
Thank you
