Hi,
We try to boot i.MX51 from NAND flash, but we have some difficulties...
1. All e-Fuses are intact (not burned)
2. We use GPIO pins to override e-Fuses (GPIO_BT_SEL = intact)
3. But not all GPIO pins are sampled to SBMR, just some...
4. For example we can set BT_MEM_TYPE to: 01 and it reflects in SBMR, but setting this to: 10 shows up as 00 in SBMR, on the iMX51 EVK board we see the same result
5. We are reading SBMR using ATK (custom nand kernel image). BMODE=00 and BMODE=10
6. If we program some binary to flash than we will not get to the serial downloader
any clues?
best regards,
Bojan
