Hi, thanks for the comment. I tried to install image as you mentioned. However the device doesn't boot and stops with following messages.
Found legacy kernel configuration
** File not found /boot/script.bin **
Image Name: uInitrd
Image Type: ARM Linux RAMDisk Image (gzip compressed)

Starting Kernel ...
I wanted to test external audio codec on I2S pin of BPI M2+ which seems cannot be configured to use with Armbian download image. In order to do any BSP level changes, i have to build the kernel.
Any help will be highly appreciated.
