BTW, I know u-boot can pass the mtdparts parameters to linux kernel. Which mtd partition info linux kernel will use, u-boot mtdparts info or static address map code ?
That's a Linux question, isn't it? And as such off topic here...
The answer is: it depends.
If you don't configure CONFIG_MTD_CMDLINE_PARTS into your kernel, then always the static partition map will be used. If you enable CONFIG_MTD_CMDLINE_PARTS and do not provide partition info on the command line, then also the static partition map will be used. If you enable CONFIG_MTD_CMDLINE_PARTS *and* provide partition info on the command line, then the command line information will be used.
Yes, I know but i'm trying to pass mtdparts to linux kernel but it still use static partitions. Thanks for your reply. I will look into the kernel source code.
