I.MX8MMini : fsl-image-validation-imx-imx8mmevk.sdcard

Hi,

Every change in the linux kernel and compiling using bitbake "virtual/kernel" -c compile -f and then doing a  bitbake fsl-image-validation-imx is taking lot of time near 3 hrs for single compilation. Is there any other way ...? so that we can modify the kernel and update in fsl-image-validation-imx-imx8mmevk.sdcard  rootfs

Also let us know, How do i mount the fsl-image-validation-imx-imx8mmevk.sdcard and update the linux image and then again convert it to fsl-image-validation-imx-imx8mmevk.sdcard

Regards

Santhosh

Hello Santhosh,

For modifying u-boot code and kernel / device, you have 2 ways to save building time.

1. Using Yocto

(1) u-boot

--> bitbake u-boot-imx -f -c compile

--> bitbake u-boot-imx -c deploy

(2) kernel

--> bitbake linux-imx -f -c compile

--> bitbake linux-imx -c deploy

2. Using standalone for u-boot / kernel

see the link, please!

or see following linux documents:

--i.MX_Linux_User's_Guide.pdf

--i.MX_Porting_Guide.pdf

open document, and search "standalone", you will see steps on how to ...
