G400 D Battery Ram?


#1

I do not see any mention of Battery backed RAM area on G400D. Am I wrong? This was an interesting feature to store user parameters even when the board is switched off.

How are you storing user parameters on G400?


#2

The G120 has about 5 bytes of RTC RAM that you can use. I’m not sure if the G400 has a similar feature, but I doubt it. There is Extended Weak References that stores stuff in flash.

Hello hagster and thanks for your answer. It seems you are right G400 seems not to have such feature.

I already wasted a huge amount of time on EWR with EMX. This was not reliable at all. Is it still as buggy as before? I still don’t understand why flash is not directly accessible… :frowning:
