问题在于设置 mtdids 时
=> setenv mtdids 'nor0=s25hs512t'
=> mtdparts
Device nor0 not found!
问题
-
我在设置 mtdids 时做错了什么？什么应该是正确的
要设置的正确 dfu_alt_info 是什么。我尝试过但没有奏效的是
env set dfu_alt_info 'mtd nor0=uboot part 1;uboot-env part 2;kernel-dtb part 3;kernel part 4;root partubi 5;'
【问题讨论】：
【参考方案1】：因此，最近 u-boot 2021.10-rc3 上包含 Serial Flash Discoverable Parameters 的补丁似乎从参数本身中提取了名称。
在驱动程序/mtd/spi/spi-nor-core.c
int spi_nor_scan(struct spi_nor *nor)
...
if (!mtd->name)
mtd->name = info->name;
mtd->dev = nor->dev;
...
虽然它在 u-boot 上破坏了 mtdparts 和 dfu（可能是其他人，不确定）是个好主意，因为它需要旧的命名约定 - nor、nand 等后缀为 dev 数字
如果我将名称静态编码为
if (!mtd->name)
mtd->name = "nor0";
我已经成功了

此解决方案不适合生产，但至少在 u-boot 人员修复之前不会破坏您的开发
