How unpack partition table from full dump NAND chip

kuzma2000

Hi!
I need to make a copy of the Nand chip.
I can't write a copy to the new chip in "Hadr Copy" "Single File" mode because the new chip has a Bad Block.
I want to use "Partition Mode" and "Skip Bad Block" mode, but I don't know what partition markup is on the original chip.

How do I know/unpack a partition table from a full dump?

I read these notes and want to figure out what to do with such bad blocks :)

These two links talked about how bypass bad blocks  - write in Partition mode and skip bad blocks.

Can you get ahead of what partitioning on a flash drive if there is only a full dump of it?
If I write only one section (the whole flash drive), how to correctly calculate the END_BLK and CNT_BLK values

I tried to record the chip in single partition mode for the entire volume (1024 blocks).
It successfully writes data to the partition but fails validation.

At the same time, the Bad Block list is empty.
I think my programmer can't identify a faulty block when programming (6.4.7.1) in this situation.

How can I manually mark/add Bad Block it to the Bad Block List?
