I have some questions regarding the i.MX28 NAND Boot Mode:
- The i.MX28 Applications Processor Reference Manual, ch. 220.127.116.11 Recovery From a Failed Boot Firmware Image Read. writes something about a SDK. What SDK? I did not found any description about this SDK in the manual.
- In the manual, ch. 18.104.22.168 NAND Patch Boot using FCB, a secondary mechanism to boot NAND patch image is described. What is a patch image? Is there any special requirements to a patch image? Can I use the patch boot to boot from NAND if both boot firmware areas are damaged?
