Re: Configure M5329 NAND for Freescale MCF5329EVB (uClinux-dist-20150808)

Hi,
First of all you have to compile the drivers if you wanna add the drivers, then you have to modify the kconfig file adding the names of the divers files *.o and *.c. Once you have added the files to the configure file you can patch the kernel and finally add the drivers configuring the kernel graphically or manually. Just follow the steps of bellow:
1) Compile drivers2) Add names of files *.o and *.c to the respective KCONFIG3) Patch Kernel using Diff tool4) Compile Kernel5) Add drivers to the configuration of custom kernel6) Compile Kernel 7) Done, you have your custom kernel with new drivers added.  
BR,
Cristobal
