Hi,
I am using a Zynq 7000 board with QSPI NOR FLASH (MT25QL01GBBB8ESF), and I am using petalinux2019p2 for my project creation
I have created 5 mtd flash partitions as follows:
5 fixed-partitions partitions found on MTD device spi0.0
Creating 5 MTD partitions on "spi0.0":
0x000000000000-0x000001000000 : "boot"
0x000001000000-0x000001020000 : "bootenv"
0x000001020000-0x000002020000 : "kernel"
0x000002020000-0x000003020000 : "spare"
0x000003020000-0x000003920000 : "jffs2"
Able to successfully load and boot kernel with INITRAMFS filesystem
Now I want to change my filesystem to JFFS2 and i have did the following
- Enabled JFFS filesystem in petalinux config
- Created an mtd partition for JFFS2
- In Petalinux config -c kernel JFFS2 has been enabled
- From NOR datasheet found the erase size to be 64 KiB and configured the same in petalinux config JFFS2 erase size
- Executed petalinux-build command and generated uboot (u-boot.elf), kernel(image.ub) and jffs2(rootfs.jffs2) images
Loaded the uboot image and set the bootargs as setenv bootargs root=/dev/mtdblock4 rw rootfstype=jffs2
At uboot flashed the rootfs.jffs2 to mtd partition 4 (flash offset 0x3020000) and loaded kernel image.
Unable to boot and we were getting the below error:
jffs2: Node at 0x00800d28 with length 0x000007f3 would run over the end of the erase block
jffs2: Perhaps the file system was created with the wrong erase size?
