about kernel linux-imx branch

[changbaoma]

when the  clone imx kernel (git clone https://source.codeaurora.org/external/imx/linux-imx), i find there are two branchs with 4.19 (5.4 also):

#git branch -a

remotes/origin/git.kernel.org/linux-stable/linux-4.19.y
remotes/origin/imx_4.19.35_1.x.0

which should we use on imx6ull？

 is the first one maintained by kernel.org and the second one maintained by nxp?

how long do those imx linux-4.19.y and linux-5.4.y will be maintained by nxp?  and how to choice?

Cloning this REPO is not working via USA ISP/DNS. If I connect to EU VPN servers then cloning this repo works fine. Does this repo have cloning issue in USA?

Comment:

1. Here is the link for all versions of linux BSP document.

Embedded Linux for i.MX Applications Processors | NXP 

Linux bsp version on the link will be maintained by us.

2. bsp for i.mx6ull

All versions starting from L4.1.15_1.0.0 support i.MX6ULL. So you can use which version.
For example: 4.1.15_2.0.0, 4.14.98_2.0.0, 4.19.35_1.1.0, 5.4.3_2.0.0 and the most recent 5.4.24_2.1.0

You can download the corresponding document from the above link, and establish your cross-compilation environment according to the iMX_Yocto_Users_Guide.pdf in the document, and download and compile the version of the BSP.

Hope above information is helpful for you!

Have a nice day!

B.R,

Weidong
