programming bank 1 flash, and readback issue.

Fri Jan 16, 2015 6:17 am

When I programmed the bank 1 flash, with the program running from bank0, 
And read it back again, the first pass checksum fails. Then if I read it again, the checksum is okay. 

I wonder if there is trick programming the bank 1 from bank0?

This is on SAM3A4C. 
I assume it is similar on SAM3U/X, 

What is the proper way to write/read BANK 1 flash while programming is running on BANK 0.
