emmc is limited to single partition ?

[ranran]

Hello,

I've read the following page:
https://www.at91.com/linux4sam/bin/view ... edMainPage
In section "Using SAM-BA to flash components to board" , there is a diagram which says that emmc is a single partition.

Does it mean we can't use more than one partition with the emmc ?

Thank you,
ranran

No, you're trying to read something that isn't there at all.
The "single partition" is merely a description of that particular demo rootfs image.

FYI the traditional Atmel layout for raw NAND flash uses three (3) MTD partitions, with the kernel, Device Tree blob, and rootfs each in their own MTD partition.
The traditional Atmel layout for SDcard uses a FAT partition for the kernel and Device Tree blob (as well as the AT91Bootstrap and U-Boot images), and an ext2/3/4 partition for the rootfs.
(These storage layouts are based on the (old) versions of U-Boot that did not have read_file_in_filesystem capability.)
So storing the kernel and dtb images in the rootfs as in that particular demo image is atypical for an Atmel example.
