We have a custom board based on i.MX6 ( Quad core version) and we are running linux on it.
The board is booting from emmC.
The POR_B pin of i.MX6 is connected to the RESETB_MCU pin of PMIC ( PF0100).
I tried to reset the i.MX6 on the board by explicitly pulling the POR_B pin to GND ( I soldered a wire out from this pin).
If I am in uboot and reset the processor , it will get reset and will reboot.
But after booting completely, that is , once we get the linux prompt, if I reset the processor , it is not rebooting.
Can somebody help me to know why is this so?
Is it because Linux configures the core voltages to a low voltage ?
