It's very likely that there's a blob for the SDRAM controller. Something like this: https://github.com/u-boot/u-boot/blob/master/arch/riscv/dts/fu740-hifive-un

- FullyFunctional 3y agoAlso the GPU doesn't have a free driver [currently]
- spintin 3y agoThe GPU doesn't have a closed driver that works either. It's been a year for the JH7110 too, so I wouldn't hold my breath. On Vision Five 2 everything is still softpipe in the official Debian from Star Five! On the PineTab-V NOTHING involving the 3D part of the GPU works! YouTube works for consumption, but that's not interesting for production. To write/film a review of a SoC with GPU without running glgears is backwards. I think the only hope now is for the upstream to gain a working driver in a year or two.

Some definitions for the variant used in JH7110 have been added recently, but it's not yet operational. 0. https://mesamatrix.net/ https://mesamatrix.net/
- dfox 3y agoI'm not sure I would call this thing a blob. It is not code, but configuration data.
