Hello, @Abhiram_m_s
I feel sorry that you still meet the issues.
It is odd from your description
I suggest creating a new directory, then reinstalling the BSP there with a separate directory created for holding the firmware
Then modify the conf/local.conf as what had done previously, and finally build the BSP by using bitbake fsl-image-auto.
If still issues, feel free sharing logs with me.
