I'm building a minimal system based on AM3358 using Bitbake/Arago and kernel 3.2 (modified psp04.06.00.10 kernel). Everything works fine, except I can't get graphics acceleration working. I'm using OMAP35X-Graphics-SDK-04.09.00.01 . Everything is built fine, but when I start the system, pvr-init fails with following errors:
