Petalinux build errors

[mohamadoussayran]

Hello,

i created a block design on vivado 2018.3 of Video test pattern generator (v8.0), frame buffer and zynq U+. 

i am trying to build petalinux using linux-xlnx tags ( xlnx_rebase_v4.14) and its last modification was in november 2018, which means the driver of Video test pattern generator (v8.0) was not modified inside the previous driver for v7.0. it just includes the driver for 5.0 and 7.0 . So it is obvious it would not be probed and that what i am got.

recently, a modifiation of the driver 8.0 was added in the branch master and not in tags. also i tried to build petalinux using the master branch but when i wrote petalinux-build , i got this error :

Ready $ petalinux-build -c kernel

it seems that it is a md5 checksum problem.

ANY SUGGESTIONS?

Hi ,Mohamad

I also encountered this problem, have you found a solution?

I cloned the linux-xlnx directory from github of xilinx using git command, and then chose to use this external Linux source directory when petalinux-config. I did not make any changes to it.

Hello @lixiansen,

No i didn't find the solution yet. I am still waiting a response from xilinx employee or someone who faced the problem and solved it.

Hi ,Mohamad

I seem to have just found a solution，You can look at this first 

The general idea is,Your petalinux version needs to match the Linux version you downloaded, otherwise LIC_FILES_CHKSUM is prompted

so，i run the commands like below （my petalinux version is petalinux 2018.3）

git checkout xlnx_rebase_v4.14_2018.3
git pull  https://github.com/Xilinx/linux-xlnx.git xlnx_rebase_v4.14_2018.3

after this，my petalinux version is consistent with the official Linux version on github xilinx

and it works fine now。

祝好

Hello @lixiansen,

I will test these commands tomorrow and i will update you.

I want to use the master branch because i want to use the last modification of the video test pattern generator v8.0.

Could you check if inside the drivers->media->platform->xilinx->tpg.c if it includes the compatibility of video test pattern generator v8. 0 after these commands?

Thank you very much 

[lixiansen]

Hi,

sorry i'm a newbie to linux,but i checked the  drivers->media->platform->xilinx->xilinx-tpg.c file and it doesn't seem to support TPG V8.0

i uploaded this file from V4.14 branch for you to check

and i founded that It was only uploaded to the main branch half a month ago, so I guess this branch doesn't support the functionality you need

祝好

Hello @lixiansen, @

hat why i want the master bran

[lixiansen]

Well,maybe you can try this way。But i didn't try。
use the “old” linux branch version (V4.14 that matches the petalinux) to generate the uboot 、fsbl and dtb file,then build the master branch of the kernel by yourself
pack the uboot、fsbl and dtb file as BOOT.BIN ，and use the uImage that build by yourself to boot the board on
may work?

hello @lixiansen,

i didnt understand what do you mean by " build the master branch of the kernel by yourself ". 

what i tested and it is not working is to copy the file i needit (includes to v8.0) to  the tags v4.14, but unfortunately , still not working

[mohamadoussayran]

can you try to build a project with the master branch to check if you will get the sale problem. 

for uboot and linux-xlnx are point to the ext-src-file in "petalinux-config " command.

thank you very much

[lixiansen]

sorry Mohamad，i am a newbie of linux,i want help but i have do my best.

but i think the best way to solve your problem is deal with the" license-checksum"of the linux

i dont know how the checksum work in linux src.Maybe find a way to update the license-checksum in the linux master branch source code is the key to your problem

祝好

Yes, This is utterly and completely broken as documented for petalinux 2018.3. A workaround is copying the COPYING from the previous build to your kernel and adding KERNEL_VERSION_SANITY_SKIP="1" to project-spec/meta-user/recipes-kernel/linux/linux-xlnx_%.bbappend.

It would be nice if there were a way to put the new info into the bbappend to override, but I don't know what that would take.

you should be able to change/override the LIC_FILES_CHKSUM as well as the version info checked by the python mess.

Solved in petalinux 2019.1
