NVRAM

Post by Purecade »

Hello,

I would like to know if RevPi contains NVRAM?If not, how does it ensure that program data is saved in case of power failure? For example, codesys program data, python program data.

Thank you
Cade

Hello Cade,

No, the RevPi devices do not have any NVRAM. All data has to be stored on the internal eMMC, which is persistent across power cycles and reboot. When it comes to remanent states, you, as a user, are responsible to make sure that the data is persisteted on the eMMC..
