There're never model A boards that are really sold. When model A is put on the website, its stock is always 0. Only model B boards are really sold. BTW from my communication with TL Lim, model A will get redesigned to get the software compatiblity with model B, if it's going to be re- available on the market again. So all known difference will be not difference between models, but difference between sample version and final version. But even if the new model A is out, it will still need a different devicetree with model B, as PCIe is model-A-only feature, and model A will have no on-board Wi-Fi (model B has RTL8723BS on-board). > > > > Model A also had HDMI, and it doesn't look like there's anything > > > particularly specific with that board. > > > > A subthread just say the opposite, modelA need something more for > > HDMI > > https://lkml.org/lkml/2019/8/12/394 > > Right, but that's not in the DT at the moment. > > Maxime > > -- > Maxime Ripard, Bootlin > Embedded Linux and Kernel engineering > https://bootlin.com > _______________________________________________ > linux-arm-kernel mailing list > linux-arm-kernel@lists.infradead.org > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel

This patch adds the evaluation variant of the model A of the PineH64. The model A has the same size of the pine64 and has a PCIE slot. The only devicetree difference with current pineH64, is the PHY regulator.
