Reseting using the reset pin also resets the Dram?


#1

Hi,

Does reseting the board using the reset pin also reset the Dram. So all the instructions need to be fetched again from the emmc.

In my opinion, nowadays, most of the boards will have PMIC and reset line will be tied to PMIC as well.
When PMIC gets a reset request, it switches off power for a short period of time and supply power again.
So DRAM contents will be lost by that time.
I think hikey PMIC might also be doing the same.

But boards like beaglebone, preserves the RAM content over reset.
