Hi Phillip
Do you think there is any hope for us getting the GPU to work on my
Element14 SABRE Lite or is it a lost cause, with it being such a rare
board combined with my lack of of kernel dev skills and limited dev
time for this? I'm sure I'll find a non-GPU dependent use for the SL
if that is the case but its a shame as its the main reason I bought
it, in the hope of finally getting an ARM device with FLOSS drivers.
When I bought it I thought it I was under te mistaken impression it
would be exactly the same board as the Boundary devices SBC of the
same, which is a pretty reasonable chance to take I thought.
It seems to me that the best iMX6/Vivante SBCs that I could
potentially afford are the Wandboard Quad, the CuBox-i2eXw or the
Hummingboard i2eX? Is there anything better choice for someone who
really wants an (e)SATA port?
Does anyone on this list own any of these devices and can you confirm
they work with etnavivdrm and Armada?
Thanks
