Of course there has been no progress on reverse engineering the epaper display driver in the past three months. Furthermore it is questionable why anyone would need to RE it, considering that the driver is in-kernel. The assembly file that rockchip shipped with their sdk seems like a GPL violation to me.
- the_biot 5y agoGood point. That page says the BSP ships with a GCC-produced driver blob, without source. Would be good to hear from the Pine64 folks on whether they've contacted the vendor and demanded source.
- rbanffy 5y agoMaybe asking politely and offering help would work better. It’s entirely possible the blob was never cleared for release as source. In the distant past I was hired to provide programs in binary form and many clients refused to pay more for source.

- rbanffy 5y agoHow many competitive ARM SoC vendors that have good software higiene out there?
- CameronNemo 5y agoWho says I have to buy an ARM SoC. I can always just check out and keep using second hand devices. Or something from Intel, if I need more power. And to answer your question, two come to mind, NXP and Amlogic.
- rbanffy 5y agoAre we still talking about Pine64? As for blobs without source, the same happens with x86 all the time. If you really want a fully deblobbed computer, you can try one of the POWER boxes from Raptor.
