Hello Flaby,

You must check the DDR of your board since is not a problem with software.

Hello Bio_TICFSL,

thank you for your reply, sorry for late response as i was not having board with me and i was not able to reply.

i calibrated DDR and board reboot problem is solved  but shutdown problem is not still resolved.

please give your feedback on this.

thanks and regards.

Hello Flaby,

I have encountered the same issue in my custom imx7d board.

Have you fixed this issue? Can you share the fix?

Thanks,

Javer

Hi Javer,

yes i was able to fix the issue with reboot, i performed the ddr calibration test and update .cfg file in <uboot-dir>/board/freescale/mx7dsabresd/ then board was rebooting fine.

late when board was loaded with few sensors in uart and spi i again faced same issue and i think this time maybe because of some running processes not getting killed.

Hope this information will help you.

Thanks,

Flaby

Hello Flaby,

Thank you very much for your suggestion.

I'll try it on my board and hope it will work.

Best Regards,

Javer
