You are very welcome.

In the first place, let me quote Ruedi Dummermuth from Abatron, BDI2000
vendor:

This passage also has a suggestion how you can use BDI2000 to program
NAND indirectly: load NAND-capable software to RAM.

I'm afraid I didn't understand you. Are you saying that you actually
were able to program NAND using BDI2000? I would like to know how you
achieved that. I suspect that was some kind of "indirect" procedure,
Ruedi wrote about, but please provide details.

See, it's not a question that BDI2000 can be used with board which has
NAND flash on it, just it's not capable of NAND direct programming as it
does in the case of NOR flash.

I also have AMCC Sequoia board with both NOR and NAND flash. On this
board you can boot u-boot from NOR first and use it to program NAND.
