Boot from NAND Flash

Hello All,

I am working on the custom board of iMXRT1176. We are exploring with the NAND memory and have some query for the same.

1. As existing memory is NOR Flash and XIP is there but in case of Serial NAND Flash it is not possible! Am i right ?

2. If XIP is not possible then for Serial NAND Flash , need to copy the code from NAND flash to SDRAM and run from there. Is ROM boot is capable of doing same ?

3. If the ROM Boot is not capable , how do the same ?

Thanks in Advance

Ankush

Hi @Ankush_9881 ,

1. Yes, NAND flash doesn't support XIP because it doesn't support random read.

2. Yes, the code in NAND flash must be read to RAM before executing. ROM bootloader is capable to do so.

3. Please see the 10.6.2 section in reference manual.

Jing
