Hi ,
I would like to know how can we generate ramdisk rootfs image for am3352 processer.
Do you have any step for the same, If Yes can you please share the step.
Thank You,
Jitendra
Hi Jitendra,
our SDK is able to generate a "tiny" image (bitbake target tisdk-tiny-image) that you can use for this purpose, specifically the cpio archive that is being generated. You can search the E2E forum, this has been asked a few times already. Another way to do it is to actually package the files you want to be in the ramdisk directly together with the Linux Kernel, see https://e2e.ti.com/support/processors-group/processors/f/processors-forum/825622/compiler-am3352-ramdisk-error/3059053#3059053

Hi Andreas,
Thank you for your reply,
we are planning to update rootfs from web but while updating it is taking around 10 min.
currently we are using core-image-minimal-am335x-evm.tar.xz image which content rootfs, dtb and zimg .
To reduce the time we are planning to use ramdisk image.
Is it possible to update rootfs file system using this?
Is there any way how we can do this ?
Thank You,
Jitendra
Hi Jitendra,
this is a little bit out of the scope what we support directly but here are some pointers for your consideration/review:
https://wiki.yoctoproject.org/wiki/System_Update
https://www.youtube.com/watch?v=j4o5TzMdOL4
I have used 'swupdate' in the past for block/media-based updates and it was generally a good experience. But as always there are different solutions/approaches, so something else may fit better for your use case.
But I did take a note, this may be a good project for a demo/application note for us to work on to provide to our customers like yourself.
Regards, Andreas
Hi Andreas,
we are planning separate kernel and dtb images from core-image-minimal-am335x-evm.tar.xz
while doing this we are updating EMMC partition like bellow
mmcblk1 179:0 0 3.6G 0 disk
|-mmcblk1p1 179:1 0 32M 0 part /boot/uboot
|-mmcblk1p2 179:2 0 512M 0 part /
|-mmcblk1p3 179:3 0 512M 0 part
|-mmcblk1p4 179:4 0 1K 0 part
|-mmcblk1p5 179:5 0 64M 0 part /_opt_application
|-mmcblk1p6 179:6 0 64M 0 part
|-mmcblk1p7 179:7 0 32M 0 part /_opt_kernel
|-mmcblk1p8 179:8 0 32M 0 part
|-mmcblk1p9 179:9 0 5M 0 part /_factry
|-mmcblk1p10 179:10 0 512M 0 part /_home_upgrade
`-mmcblk1p11 179:11 0 1.9G 0 part /_opt_data
mmcblk1boot0 179:16 0 2M 1 disk
mmcblk1boot1 179:32 0 2M 1 disk
I am able to load the kernel image using changing the environment variables.
devtype=mmc

bootfile=zImage
fdtaddr=0x88000000

loadfdt=load ${devtype} 1:8 ${fdtaddr} /${fdtfile}
but looks to be in log uuid value not getting. Due to this facing kernel panic issue

Hi Andreas,
I am able to boot from kernel partition after changing environmental variables.
loadimage=load ${devtype} 1:8 ${loadaddr} /${bootfile}
loadfdt=load ${devtype} 1:8 ${fdtaddr} /${fdtfile}
args_mmc=run finduuid;setenv bootargs console=${console} ${optargs} root=/dev/mmcblk1p3 rw rootfstype=${mmcrootfstype}
after that I copy ramdisk image in partition mmcblk1p3 but I am getting bellow error.
