Hello every one?
I am working with a compact flash, wich controller is a sm2236g-ac and 2 nand flash memorys of 8GB.
The vnr dont have the configuration for the memorys, the part number is 029f64g08aecdbj4 and the id is 2C44403CA5.
I could make some progress with the configuration, in the vnr i set a page size of 17632, block size of 256 page per block (size in bytes of 4513792) and the plane size of 2048 (size in bytes of 9244246016). Both page size and plane size set the same value to nominal and real. In plane and crytal i set 1.
With this configuration the first half of the dump have data and the second half is empty.
After this i try to read with this settings:
page size of 17632
block size of 256 page per block (size in bytes of 4513792) the same value in nominal and real
In nominal i set a plane size of 2048 (size in bytes of 9244246016) and in real i set a plane size of 1024 (size in bytes of 4622123008)
plane 2
crystal 1
This time all dump have data, but after i find the xor key and search the file system is like with this configuration in the reading process blocks were repeated.
I tell how I came to that conclusion, I found the LBN and with the markers table sorter all the blocks, observe that the LBN always repeated 2 times, measured the distance between the repeated blocks, on pages, and it is always half of the dump
I clarify that I tried several combinations of vsp signal
I dont have technical support this moment, anyone who can give me a hint i am very grateful.
thanks very much
