@Justin Thanks for the correction (a slip of memory on my behalf). Anyway the Ultra96 is gen2 socfpga all the others we have are gen1(armhf 32 bit without hw gpu) Hence I find the price within reasonable (and my budget...)
What also could be interesting is that I thought I saw somewhere that the R5's should be software compatible with the R4's in the BBx15/AI's ..? The mali lima project (mali 400 open source) went into mesa 19.1 recently and also into the 5.xx? kernel around may or so.
