/RESET timing on OMAP-L138

Dear All,

I am trying to verify if my warm restart duration is correct - it works at ambient temperatures but once at elevated temperatures things go not to plan.

I have an external FPGA which controls the /RESET line for a "warm " reset; it asserts for 200 uS duration. This works except for at +80 degrees (I am using the 'A' part OMAP rated for 105 degrees).


I have been looking over the documentation and I cannot find (again) the note where I got the 200 uS from - is it too short ?

Also, I could do a cold start but am not sure if that is required - I do not use the RTC and the memory content should be replaced once I boot ?

All the best


Boris
