That would be Amlogic. Why would they care about anything that doesn’t result in selling millions of SoCs?
Here’s Christian’s insights on what to expect from Amlogic and this latest version of their BSP kernel mess (and why A311D2 isn’t just an A311D with an added 2 but something new and entirely different):
What’s at the heart of VIM4 will be soon selling in the millions as this thing. That’s Amlogic’s market and not a few thousand SBC here or there.
Given the crappy I/O capabilites of this Amazon box most probably the whole PCIe thing inside this SoC has only been tested with Wi-Fi chipsets and not storage/NVMe. But who knows? At least it should be well understood that Amlogic does and cares only about TV boxes and the like and that I/O with Amlogic was always crap and will most probably remain crap in the foreseeable future. Since why would a TV box need decent I/O capabilities?
