Hi,
I have been searching the archives and I've seen posts that suggest that the bootcount feature is trivial to implement in non PPC cpu's but haven't seen a discussion of what would be involved or ideas on how to go about it.
I have flash (where the u-boot env. vars are stored) and EEPROM via I2c. My ARM926ejs variant has SRAM on chip, but I'm not sure of its state on reset yet.
So should I use flash or eeprom to store the bootcount? I know it was originally intended to increment only on reset (not power cycle) but I don't know how I can accomplish since I asked chip vendor if any registers survive reset and the answer was "no".
Looking for ideas on the best way to go about implementing this feature for a ARM926ejs based core. Actual chip is picoChip PC205.
Regards,
Brian
