vpu_suspend failure

[susangracerapak]

Hi all,

I am testing suspend and resume functionality on imx6Q with android nougat. When i try suspending, module trying to go into suspend state and getting below issue and then resuming.

dpm_run_callback(): vpu_suspend+0x0/0x158 returns -11
PM: Device 2040000.vpu_fsl failed to suspend: error -11

This is happening continuously (meaning trying to go into suspend and resuming on failure) until i try resume (By moving mouse or pressing power button).

Please help in finding why suspend failing. 

Please find attachment for full log.

Thanks

Susan

Hi Susan

one can try to reproduce issue on i.MX6Q Sabre SD reference board with Demo Images from

https://www.nxp.com/support/developer-resources/run-time-software/i.mx-developer-resources/i.mx-6ser...

If issue can not be reproduced, one can retest ddr memory on custom board and update image

with new memory calibration coefficients found from ddr test:

i.MX6/7 DDR Stress Test Tool V3.00 

Rebuild image from scratch using nxp android sources:
