the 9260 has
8 KBytes Data Cache, 8 KBytes Instruction Cache, MMU
• Memories
– 32-bit External Bus Interface supporting 4-bank SDRAM/LPSDR, Static Memories,
CompactFlash, SLC NAND Flash with ECC
– Two 4-kbyte internal SRAM, single-cycle access at system speed
– One 32-kbyte internal ROM, embedding bootstrap routine
NAND flash does cone in big memory sizes. they are too big for your application and costly tooo.
if you need you can boot from SD card, but the available options are Boot from NAND Flash, SDCard, DataFlash or serial DataFlash.
