Re: Late feedback on July Update:SOLVED

@NTN

Well, my knowledge of electronics may be a bit outdated.

By "CMOS" I meant battery backed memory storage. Since all of my UBOOT variables were reset during the battery change, I assumed that they were stored in CMOS RAM.
Had they been stored in FLASH, they would not have reset when the battery was changed.

In any case, there is still the open question of why the latest update requires a stonger battery than the previous one.
With my apparently borderline battery, the problem appeared within moments of loading the new kickstart modules, and disappeared as soon as the previous ones were put back.

I think that is a clue that deserves further investigation.

Have a nice day,
LyleHaze


Question: If the UBOOT vars are stored in NVRAM, why would they be lost on a battery change? By definition NVRAM does not require power to retain its contents.
It sure looks a lot like SRAM to me.
