Linux v5.10 for i.MX8 development


Ankur Tyagi
 

Hi,

We are currently using Linux v5.4 for i.MX8 provided by recipe linux-fslc-imx_5.4.bb because as mentioned in recipe as well, branch "5.4-2.3.x-imx" from repo "linux-fslc" get changes merged from branch "imx_5.4.70_2.3.0" of linux-imx repo (https://source.codeaurora.org/external/imx/linux-imx/log/?h=imx_5.4.70_2.3.0)

Now we are planning to upgrade to Linux v5.10 and here I have few questions:

  1. Recipe linux-fslc-lts_5.10.bb doesn't support i.MX8 https://github.com/Freescale/meta-freescale/blob/325ad529187fb1309b0a889c5196c8df039aeea9/recipes-ke... Neither I can see any merge from NXP linux-imx branch "lf-5.10.y" into linux-fslc branch "5.10.x+fslc". Is there any plan for that merge? If yes, any timeline by which it will happen? If no, then can I use "imx_v8_defconfig" from linux-imx repo to build kernel using linux-fslc repo?
  2. i.MX8 is supported in linux-imx_5.10.bb recipe https://github.com/Freescale/meta-freescale/blob/325ad529187fb1309b0a889c5196c8df039aeea9/recipes-ke... which is using kernel from branch "lf-5.10.y" provided by linux-imx repo but this repo is NXP internal and doesn't get updated with stable Linux kernel. It is providing v5.10.35 (https://source.codeaurora.org/external/imx/linux-imx/log/?h=lf-5.10.y)

    So ideally, just like v5.4 would like to use linux-fslc repo for v5.10 development as well.

Will appreciate any guidance around appropriate repo for v5.10 development for i.MX8

thanks
Ankur
