Try to show the prototype and need feedback see if people would be interested in this kind of product.
Read NAND flash directly on the board seems possible now with the new type of clip and u-Link NT (USB JTAG NT) software is easily modified to access it. I have also tried router EA6400 with success.
NAND flash by nature has bit errors and ECC is used to fix them. Raw read could not do it properly. There might algorithms needed to fix the raw data bit errors based on ECC.
