My NAND flash 32m,kernel 2.6.18, Rootfs is EMB Linux, Cramfs. The NAND flash partition is as follows: static struct Mtd_partition nand_partitions[] = { /* Bootloader (UBL, U-boot, BBT) in sectors:0-14 */ { . Name = "Bootloader", . Offset = 0, . Size = * Nand_block_size,//32x16 = 512k . Mask_flags = mtd_writeable,/* Force Read-only */ }, /* bootloader params in the next sector 15 */ { . Name = "params", .

seems that these words gave me information.0x8fee5000: flashdrv. dll: l2p_getphysicalsectoraddr ()-Secondary table doesn't exist for logical sector1. What does secondary table mean?0x8fee5000: flashdrv. dll: readfrommedia ()-unable to determine physical sector address for logical sector 0x0000ea402. readfrommedia is a function in FAL. It cannot be seen in ce5. This statement cannot convert logic sector into a real physical address. Is the logical start address in my Partition Table incorrect ??

Abstract: Taking Samsung k9f2808uob as an example, the interface circuit of NAND Flash and S3C2410 is designed.The Design and Implementation of flash in the ARM embedded system are verified on uboot. The designed driver is easy to transplant and can simplify embedded system development.

Design of starting U-BOOT from nand flash memory Introduction As embedded systems become increasingly complex, the demand for large-capacity data storage becomes increasingly urgent. However, hard disks cannot be widely used due to the low power consumption, small size, and low cost requirements of embedded devices. Nand flash memory devices are rapidly evolving to meet this demand. At present, the U-BOOT

For many consumer audio and video products, NandFlash MemoryIt is a better storage solution than hard drive, which is particularly evident in low-capacity applications with a size not more than 4 GB. As people continue to pursue products with lower power consumption, lighter weight, and better performance,NandIt is proving very attractive. The nand flash memory array is divided into a series of KB blocks, which are the smallest erasable entities in th
