Is it Samsung K9GAG08U0M or Samsung K9GAG08U0D Because you have given the datasheet of the “D” part
Look at the 4th ID byte format. It will be different from the M part. RBL code is designed such that it will operate correctly for the M part. The board is booting from NAND by making some sense of the 4Th id bytes. This is assuming that you are using the Samsung K9GAG08U0D and not Samsung K9GAG08U0M. Both Linux and U-boot are such that they assume the old 4th ID byte format.

In ..\ \flash_utils\DM36x\Common\src\device_nand.c //FOR DM365,referred DM365 ROM code const NAND_CHIP_InfoObj DEVICE_NAND_CHIP_infoTable[] = { ………………………….. ………………………….. { 0xD3, 8192, 64, 2048+64}, // 1 GB { 0xD5, 8192, 64, 4096+128}, // 2 GB { 0x00, 0, 0, 0} // Dummy null entry to indicate end of table }; Will the below nand flash type be supported or not?? { 0xD3, 4096, 128, 2048+64}, // 1GB Samsung K9G8G08U0M { 0xD5, 4096, 128, 4096+128}, //2 GB Samsung K9GAG08U0M [Sandeep] can you share the data sheet of this device? The K9GAG08U0M can boot into u-boot, but I can’t use the U-boot command “nand write”, It seems to have some bug in U-boot!! And K9GAG08U0M can’t work!! I had check the document SPRUFG5 “Arm subsystem reference guide” The K9GAG08U0M isn’t in Table 114. Device IDs of NANDs supported. Number of pages per block is 128, not 64.
