We have a working iMX27 design using Micron NAND with Windows CE.  Using advanced toolkit 1.71 to load code the procedure is to set the "Program" and "BI Swap" operation flags to program XLDR and EBOOT and all works well.  Unfortunately, for a couple boards the "BBT" flag was set instead of "BI Swap" (something the manual warns against doing).  We tried reprogramming them with the correct settings and while they program OK they do not boot.  Tried a full erase, etc., no luck.  Any way to recover these boards using ATK or do I need to replace the FLASH part?
