ls1021atwr: Missing uboot ramdisk with sdk 1.9

[vsiles]

Hi,

I'm using a LS1021atwr board, with NXP SDK 1.9

Following the documentation, I'm trying to boot Linux from the Flash.

Both build instructions and Ramdisk Deployment from TFTP refer to a

• fsl-image-<machine>.ext2.gz.u-boot - ramdisk image that can be loaded with U-Boot

But in my build folder, I only get a fsl-image-full-ls1021atwr-20160321145603.rootfs.tar.gz with is refused by bootm with

Wrong Ramdisk Image Format

Ramdisk image is corrupt or invalid

How can I procude such a gz.u-boot file ?

Best,

Vincent

Hi all,

I got this error when i tried to build ext3.gz

Ok, now it boots ! I've got quite some errors but at least linux is started.

Many thanks to you !

Vincent

Hello vincent,

Can you share me the bb file for how you got the ext2.gz.u-boot file.

Thanks for help.

Regards,

Manju

[vsiles]

Sure, here are my local.conf and bb file

Best,

Vincent

Vincent,

Are you using sd card boot? If yes, why don't you use tar.gz image, create a linux partition on the sd card and untar the image?

For "Ramdisk image is corrupt or invalid", make sure the image is not override uImage, when is loaded in RAM.

Adrian

[vsiles]

I already successfully started using sd card boot, but since I have issues performing secure boot from sd card, I wanted to boot from ramdisk, and try an "out of the box" secure boot from ramdisk as described in the SDK. So I'm trying to boot from ram disk atm.

Since I'm trying to flash the -full-, the ramdisk is way bigger. I'll try to put the dtb further away. Thank you for the suggestion !

[vsiles]

I almost got it. When I flash the file and perform the 'bootm' command, I get (after some computation time)

## Loading init Ramdisk from Legacy Image at 88000000 ...

   Image Name:   fsl-image-full-ls1021atwr-201605

Ramdisk image is corrupt or invalid

However verification of the kernel is fine. I'll investigate. If you have any suggestions, do not hesitate :smileywink:

[vsiles · Accepted solution]

It seems that patching the IMAGE_FSTYPES_qoriq in fsl-image-full.bb to add ext2.gz.u-boot  did the trick, I got the file generated. i'll try to flash it. Thanks for the information !

[addiyi]

Try also bitbake -c compile -f fsl-image-full

Adrian

[vsiles]

Thank you for the suggestion.

With fsl-image-core, I have manage to get fsl-image-core-ls1021atwr.ext2.gz.u-boot.

Should I comment the "IMAGE_FSTYPES_qoriq" in fsl-image-full.bb to test if I get a *-full-* version of ext2.gz.u-boot ?

[addiyi]

Could you try to bitbake fsl-image-core, of course with IMAGE_FSTYPES = "tar.gz ext2.gz ext2.gz.u-boot jffs2 ubi" in QorIQ-SDK-V1.9-20151210-yocto\sources\meta-freescale\recipes-fsl\images\?

Adrian

[addiyi]

Go to QorIQ-SDK-V1.9-20151210-yocto\sources\meta-freescale\recipes-fsl\images\ and add ext2.gz.u-boot into fsl-image-minimal.bb as below:

IMAGE_FSTYPES = "tar.gz ext2.gz ext2.gz.u-boot jffs2 ubi"

Adrian

[vsiles]

I tried to add a variable in my local.conf file, and it seems to be ignored:

bitbake -e virtual/kernel | grep ^IMAGE_FSTYPES
IMAGE_FSTYPES="ext2.gz.u-boot tar.bz2 ext3 sdcard"

but I only get a tar.gz file, neigher ext2.gz.u-boot nor .sdcard file

[vsiles]

Dear addiyi​, this value already contains this exact value. I tried to modify the IMAGE_FSTYPES_qoriq of the fsl-image-full.bb file, but it did not help. Maybe this value is overridden somewhere else ?

Best,

Vincent
