Hello,
I would like build driver linux media, that's why I need config file to build kernel 3.4.39. Default config file create zImage 4,5MB, but kernel image from Dolphin is 9MB. Where I find file config from sun8iw7p1_android_dolphin-p1_uart0.img?
Depending on how the kernel was built it may have a copy of the its config actually built into it.
Try booting the img file and going to a root shell prompt (using the debug port) and then run the command
cat /proc/config.gz | gunzip > kernel.config
Copy code
This should create the text file "kernel.config" containing the kernel build options. If /proc/config.gz does not exist it was not built into the kernel.
