I would suggest to first reproduce the kernel that boots. Then you can
add to it selectively. Most likely you will need the following settings:
CONFIG_MTD=y
CONFIG_MTD_BLKDEVS=y
CONFIG_MTD_BLOCK=y
CONFIG_MTD_M25P80=y
CONFIG_MTD_SPI_NOR=y
CONFIG_SPI_CADENCE_QUADSPI=y
CONFIG_OF_MTD=y
For the root
Thanks Ralph,
Your 2 cents were worth more than 2 cents.
I am feeling "less stupid" and will look at the kernel settings again. I sure
thought I had what I needed for flash and MTD blocks.
For the minimal root filesystem - I should be able to get a root filesystem
that works and just update
Hi Janet,
My $0.02 here: the *.dts entries look semi reasonable, you have a flash
device and two partitions defined therein. The second one is labelled as
jffs2 which matches with your root=/dev/mtdblock1 on the kernel command
line. So far, so good.
Therefore you are likely missing some drivers
I have never used the Altera tools because they are are difficult to work
with compared to normal Linux tools.
Have you ever tried using buildroot as a build environment? That works
pretty well.
That said, building a squashfs file system is very simple it is just a step
in the final rootfs
