The second week of U-boot debugging is started today. You can directly download U-boot to DDR through bdi2000 and run it successfully. However, no matter how hard it is to be written to NAND Flash, it cannot be boot. You can use the NAND Operation Command in U-boot to confirm that the write operation is correct. Let's talk about the NAND operation commands in U-

ROM (FLASH memory is often used). commonly used file system types based on storage devices include: jffs2, yaffs, cramfs, romfs, ramdisk, ramfs/tmpfs, etc. 1. FLASH-based file system As the main storage medium of embedded systems, Flash memory has its own characteristics. The Flash write operation can only change 1 of the corresponding position to 0, but not 0 to 1 (Flash erased restores the content of the corresponding storage block to 1). therefore, generally, when writing content to Flash, y

Gary Orenstein said, "In addition, our all-in-one machine maintains the highest performance record of the vmark benchmark test. Therefore, our latest atomic series will focus on application acceleration ." Gary Orenstein believes that the atomic series products are the most outstanding products of fusion-Io.

OK6410, which uses the U-Boot provided by Samsung and does not support UBI. So come up with another method to burn the data. They used their own SD card burning tool: SD_Writer, which first burned an mmc. bin and a zImage-sd file to the sd card, the former mmc. bin is actually used for sd card startup. The latter zImage-sd is a kernel file. First, let's take a look at what mmc. bin has done. Start from the SD card and enter the U-Boot download mode. Use printenv to print the environment variabl

. These include KickStart, s1l, and U-boot. kickstart needs to be stored in the 0 sector of NAND Flash (by the way, in the smartarm3250 NAND Flash, the size of one sector is kb, starting from 0, the corresponding address is 0x00000000); s1l is Stage 1 loader, which is stored in Sector 1 and serves basically to initialize and guide smartarm3250, these two files (Kickstart. both bin and stage1.bin.pdf are tra

In the embedded field, Flash is a common storage device, flash flash memory as the main storage device of embedded system has its own characteristics. Fash Write operations can only modify the corresponding location of 1 to 0, but not the 0 modified to 1, and erase Fash is the corresponding storage block to restore the contents of 1. Therefore, in general, when writing to fash, you need to erase the corresponding storage interval, which is done in blocks (Bock). Flash memory mainly has nor and

devices. However, in recent years, Flash has completely replaced the position of RoM (EPROM) in embedded systems, it is used to store bootloader, operating system or program code, or directly used as a hard disk (USB flash disk ). Currently, there are two types of FLASH: nor flash and nadn flash. The reading of nor flash is the same as that of our common SDRAM. Users can directly run the code loaded in nor flash, which can reduce the capacity of SRAM and save costs.
