ATK - BI Swap / BBT set incorrectly

ambw — Tue, 06 Aug 2019 14:24:17 GMT

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?

Thanks.

Hello,

Have You tried to erase NAND via the ATK toolkit with BBT option?

Yes, I tried that - did not help but one question with erase, what is the proper length value to use with NAND FLASH? It does not seem to be the device capacity (1Gb MT29F1G16ABBHC) as I get "failed:the input operation size exceeds the flash capacity!" with higher values.
