Problem with Trimffs enabled in PMECC for SAMA5d3 in at91boo

Mon Jun 05, 2017 9:48 pm

Hi,

I am having problem if Trimffs in enabled in PMECC for SAMA5d3 SAM-BA programming. Once Trimffs is checked, at91bootstrap does not boot up at all. The debug serial shows Romboot and it seems bootstrap is not recognized at all.

Can someone help. This is critical for me!

Thanks,
Derong

What makes you think you need to use the TRIMFFS option?

This is a problem of your own making.
The sole purpose of the TRIMFFS option is to satisfy a UBIFS requirement when writing a UBI image.
There is no other reason for using the TRIMFFS option.

Therefore the solution to your problem is obvious and simple.
Don't use the TRIMFFS option when writing AT91Bootstrap to flash.
