ROCKPRo64 Engineering Change Notice ECN:20180628RP01 This ECN applies strictly to ROCKPro64 Board ver. 2.0, dated 2018-04-11. It is applicable to boards with both 2GB and 4GB memory. Issue: The PCIe 3.3V power is not supplied; in result PCIe is not functional. Solution: Remove R89538 resistor that affects U7109 TCS4484B power regulator, supplying 3.3V to the PCIe Bus. The ROCKPro64 ver. 2.0 schematic can be downloaded from the PINE64 wiki: http://files.pine64.org/doc/rockpro64/ro...20-SCH.pdf The ROCKPro64 ver. 2.0 board component layout reference is also available at the PINE64 wiki: http://files.pine64.org/doc/rockpro64/Rockpro64- ver2.0-topsilk_ref.pdf[quote]
I presume it might have 3.3v, we need to know now how many amps if power has 5A is not enough for a low end GPU, but if it can use more, maybe it will. Acube-systems has a board to run AmigaOS with CPU PPC, it can run PCIe with ATI cards. Maybe the GPU BIOS boot thenhave to be software rather than physical.
