Hi All,

3. # nand erase 0 40000
4. # nandecc hw
5. # nand write.i 80000000 0 40000
These commands will transfer the .ifs to nand in order to be loaded by
the QNX IPL

Sounds like you trashed your NAND. Holding the USER BUTTON down while powering up will force it to boot from the SD card. To restore the NAND to the factory state follow the instructions here:
