Hi ,


We are working on P1021 customized board. We tested with NAND flash and we observed P1021 Processor  is booted successfully.  Now when we tried with NOR flash we were able to  load  images into NOR flash by using Ethernet communication port. After Loading the images P1021 is not able boot from the NOR flash. Boot Configuration for NOR flash is  set to cfg_rom_loc[0:3] : 1110.

Here are following queries.


1.Is it mandatory to write Boot_sequencer to  boot P1021 processor from  NOR as we didn't write the boot_sequencer for NAND flash booting. If yes  how  the  Boot_sequencer is written for NOR.

2.What are the conditions  need to check and any other Init process is required while  NOR booting.


Can anyone share  the P1021 NOR booting sequence.
