Hi,

 

We are working on iMX8QM custom board with 4.14.98 Kernel BSP release with 'imx-scfw-porting-kit-1.2' SCFW.
The iMX8QM B0 CPU is able to do soft reset (reset command in u-boot & reboot command in kernel) , but the same soft reset is hanging for A0 CPU.

 

But  in iMX8QM A0 CPU able to do soft reset If we use 4.14.78 BSP with 'imx-scfw-porting-kit-1.1.2' SCFW source code.

 

Is there any CPU restriction/bug for iMX8QM A0 CPU soft reset in imx-scfw-porting-kit-1.2 SCFW or 4.14.98 Kernel BSP release? How to resolve this soft reset issue for A0 CPU?

 

Best Regards,
