I refer to
i.MX_BSP_Porting_Guide.pdf, 2.11 Get the Linux source code.
$ git clone https://source.codeaurora.org/external/imx/linux-imx -b L4.9.123_2.3.0_8mm-ga
it tells me :
fatal: Remote branch L4.9.123_2.3.0_8mm-ga not found in upstream origin
then I can we download the source code to build our own kernel
Hello Jiye,
Try to download the porting guide again, since you are referring to L4.9.123 and its wrong you have to L4.14.98.
