Hi Terry, I would start by contacting the vendors who build the capes you are using and ask them which kernel version do they currently support. BTW, I wouldn¹t call v3.2 kernel old; I would call it stable, which is what you want. Linux consists of the kernel (zImage), kernel modules and firmware. Usually, zImage is installed on the FAT partition together with MLO (x-loader), u-boot and uEnv.txt. On the second partition, you find the filesystem (OS) and in the /lib folder you will find the modules and firmware folders. If you look in the modules folder, you will find the kernel modules for each Linux kernel installed. If you look at one of these folders, you will find a folder called kernel. This is where you will find the kernel modules (drivers) for that specific Linux kernel version. When you change the zImage on the FAT partition, it will load the drivers from the correct modules folder. If you want to know which modules folder is current, use Œuname r¹. Best place to find the Linux kernels is Robert Nelsons site which you should find from the wiki (hopefully Robert reads this e-mail and suggests the most stable kernel). From there, follow the wiki to install the zImage, kernel modules and firmware. I hope this helps.
