Waking up Cortex-M4 from Cortex-A7-0 in STM32MP1 for Bare metal.

[Navaneeth kumar]

we are developing the application by using STM32MP1 processor in bare metal.

we are able to wake up Cortex A7-1 from Cortex A7-0 both are working fine. Now we tried to wake up Cortex M4 from Cortex A7-0,But we are unable to wakeup Cortex M4 from Cortex A7-0.

Individually Cortex M4 is working fine with JTAG .and we can able to wake up Cortex M4 from UBOOT By using RPROC commands .

But in our application we need to wake up Cortex M4 from cortex A7-0 in bare metal. Can you give the sequence of waking up cortex-m4 from Cortex-A7-0 in Bare metal.

Please help us in this regards..
