u-boot使用mtdparts提示Devicenand0wasnotfound的解决方法 tekkaman修改版uboot使用config_mtd_device后不能正常访问nand的种原因 原创作者:桃核(peachstone,又名sixiangzhe) 背景: 我使用的是tekkaman修改版本的u-boot源代码,使用其中的make mini2440_congfig进行编译...
当mini2440.h中不加入#defineconfig_mtd_device时,可以正常的访问nand flash,正常的烧写内核 加入config_mtd_device后,发现nand0不可用,即在执行nand命令和mtdparts命令时,都提示 Devicenand0 was not found 原因: 经过1天的时间阅读nand命令和mtdparts命令相关的代码,我发现, driver s/mtd/nand/nand.c中 static v...

这是什么启动模式,是nand启动模式吗?若是的话,说明烧录工具已经将uboot烧录到nand中了,所以nand硬件不存在问题。而在bootROM从nand中将uboot复制到DDR后,会运行uboot ,而uboot会再次初始化NAND,从现象看,显然是uboot的nand驱动不支持你所用nand,nand驱动在uboot很容易找,相信只要稍微修改就能...
0 MiB 还是不行 然后在打印语句上下功夫,代码中搜No NAND device found!!! 找到了drivers/mtd/nand/nand_base.c 这个文件 int nand_scan_ident(struct mtd_info *mtd, int maxchips) { int i, busw, nand_maf_id; struct nand_chip *chip = mtd->priv; ...

Hit any key to stop autoboot: 0UBOOT # I didn't take care to the "No NAND device found!!!" -- actually, the u-boot was indeed read and run from the NAND -- How could be any errors in the NAND? However, when I tried to set the bootarg and using the 'saveenv' cmd, the...
SD/eMMC/NAND flash controllers do not have Option ROM, so the first part of this requirement does not apply. EFI support is required.Additional InformationExpand table Enforcement Date Jun. 01, 2009Device.Storage.Controller.Boot.BitLocker
USB启动 Linux,挂载SD NAND/TF卡 U ERROR: Allwinner USB FEL device not found! 参照 晕哥的 https://whycan.cn/t_2449.html 先拿nano 测试1、nano 时TF 卡启动的,usb 连接PC 只是做供电还是还能挂载吗 ?2、后续自己PCB 使用SD NAND 离线 #
