Compilation

You can see that 3 parameters (-f, -p, -q) need to be passed when the Release_to_customer.sh script is executed;
-f represents the type of flash, optional nand, nor;
-p represents the chip model, optional ssd201, ssd202;
-q means fast boot mode, fastboot and others are optional;

Here takes nand+ssd201 as an example to start compiling the source code:
#./Release_to_customer.sh -f nand -p ssd201
After the compilation is complete, the system image will be generated in the images directory.

After compiling once, if you do not change the chip model, you can comment the make clean of uboot and kernel in Release_to_customer.sh.
