USB support in U-Boot for DM8168

Ivan Todorovic

Hello,

I'm trying to enable the support for USB devices in U-Boot (specifically, FAT32-formatted USB flash drives so uImage can be loaded from them) for our DM8168-based board (silicon revision 2.0). USB itself is working fine at the Linux stage, and the entire BSP (including U-Boot) is derived from the EZSDK.

I see that the USB support in U-Boot for this platform is completely disabled (including "usb" command in U-Boot), and the problem is it's platform dependant. I tried using USB-related settings from include/configs for other platforms (especially for davinci and omap2/3) but no luck, U-Boot can't build. Kernel loading guide at ti.com covers loading uImage from USB drive in general, but the DM816x PSP page doesn't say anything about USB in U-Boot. I will appreciate any guideline for solving my problem.

Thanks!
