Hi,
What is the maximum Nand Capacity supported by ROM boot loader in DM369
Thanks
Manoj
Hi Manoj,
Supporting NAND devices are indicative of the max NAND size supported by RBL. It also depends on the page size/the spare area size/error correction etc. It would be safe to pick one of the supported NAND devices.
Having said that suggest you to refer 
, section 4.2.1 Boot Modes Overview
ARM ROM Boot - NAND Mode
– No support for a full firmware boot. Instead, copies a second stage user boot loader (UBL) from
NAND flash to ARM internal RAM (AIM) and transfers control to the user-defined UBL.
– Support for NAND with page sizes up to 4096 bytes.
– Support for magic number error detection and retry (up to 24 times) when loading UBL
– Support for up to 30KB UBL (32KB IRAM - ~2KB for RBL stack)
– Optional, user-selectable, support for use of DMA and I-cache during RBL execution (i.e.,while
loading UBL)
– Supports booting from 8-bit NAND devices (16-bit NAND devices are not supported)
– Uses/Requires 4-bit HW ECC (NAND devices with ECC requirements ≤ 4 bits per 512 bytes are
supported)
– Supports NAND flash that requires chip select to stay low during the tR read time
