I'm not a NAND expert, and I can't give educated advice. However, if you have a working GEL file, you can try isolating the important initialization by 1. commenting out some parts of the GEL file 2. booting the board with JTAG disconnected 3. connecting the JTAG and executing GEL initializtions 4. loading your NAND test application > Of course, even with the emulator code, after > flashing succesfully the u-boot and after calling > Nand_Copy, if I jump to application start address > 0x81080000, the u-boot comes up, but with the ecc > error hot on my trail: > > NAND:nand_read_ecc: Attempt read beyond end of device > 100000 4000 0 > Did you modify u-boot sources to support your NAND part? By default the ti-supplied u-boot is hardcoded to recognize only a limited number of 512b devices.
