Linux_3.10.17 on imx6q custom board has issue with reboot/restart command

[shilpasb]

Hi ,

     We have freescale's imx6q processor on our customized board. We are using u-boot-fsl-2013 and kernel_3.10.17 versions for booting. Everything works fine except for the reboot/ restart. The system tries to reboot, but hangs after  powered off and tries to restart. Has anyone come across this issue? If any workarounds, please suggest.

Hi shilpa

one can check below

Re: mx6q reboot problem

One Freescale SDB board (SPF-27392) iMX6_SABRE_SDB_DESIGNFILES

PMIC PWRON is connected to WDOG, so at reset both PMIC and processor are reset.

If custom board has not such connection, so in uboot LDO bypass

mode processor can not start, since it has low voltages (PMIC not reset).

By default, the uboot LDO bypass is enabled.

Best regards

igor
