ls1021atwr boot issue

matt8156 — Thu, 24 Aug 2017 11:01:02 GMT

I am trying to load a new OS image onto the LS1021ATWR development board and having a few problems.

I have downloaded and installed the QorIQ SDK V2.0-1703 including the "image" iso. I have built the core and minimal OS images and attempted to boot from the SDcard by loading the images to a ramdisk and booting from this. However i get a few errors once the filesystem is mounted which include:

Bad inittab entry at line 5

and

can't open /dev/si: No such file or directory
can't open /dev/~~: No such file or directory
can't open /dev/l0: No such file or directory
can't open /dev/l1: No such file or directory
can't open /dev/l2: No such file or directory
can't open /dev/l3: No such file or directory
can't open /dev/l4: No such file or directory

I have tried the same test using the pre-built images from the SDK Images iso and get the same errors.

I have also compared the inittab file to that pre-installed in the NOR flash on the development card and line 5 appears to be identical.

My uboot environment for testing against the pre-built images is

baudrate=115200
bootargs=‘root=/dev/ram0 rw rootdelay=5 ramdisk_size=40000000 console=ttyS0,115200’

and i have attached a log of the boot sequence.

Any ideas?

Thanks

Test your board using u-boot on SD card from the QorIQ SDK V2.0-1703.

Find the "Programming U-boot to SD card" in the Section 4.4.4.7 of NXP SDK 2.0-1703 documentation:

http://www.nxp.com/docs/en/supporting-information/QORIQ-SDK-2.0-IC-REV0.pdf

OK, There do not seem to be any pre-built images for the ls1021atwr in the V2.0-1703 download.

I have built the images myself but which one should i use? the instructions you refer to do not define the file.

I would guess it is u-boot-nor.bin?

Hi,

It appears i'm having the same issue with the LS1046ARDB.

i get the same errors after the kernel starts up:

Bad inittab entry at line 5

and

can't open /dev/si: No such file or directory
can't open /dev/~~: No such file or directory
can't open /dev/l0: No such file or directory
can't open /dev/l1: No such file or directory
can't open /dev/l2: No such file or directory
can't open /dev/l3: No such file or directory
can't open /dev/l4: No such file or directory

I can't get your pre-built images to work because you don't provide the rootfs which i need to load from the SDCard on this target

Any further suggestions?

Thanks
Matt

Find u-boot image files in the following folder:

QorIQ-SDK-V2.0-20160527-yocto/build_ls1021atwr/tmp/deploy/images/ls1021atwr

Find the following file:

u-boot-sdcard-ifc-2016.09+fslgit-r0.bin

See the Section 4.4.4.7 of nXP SDK 2.0-1703 documentation:

http://www.nxp.com/docs/en/supporting-information/QORIQ-SDK-2.0-IC-REV0.pdf

Hi,

Thanks for your replies, I fixed my issue by reinstalling the QorIQ SDK and rebuilding the OS. Updating Uboot was not necessary.

This worked for both the LS1046ARDB and LS1021ATWR.

Thanks

Matt
