  1. These are the 2 patches we ended up with. With thanks to everyone at on the linux-sunxi irc, particularly megi. diff --git a/drivers/clk/sunxi-ng/ccu-sun8i-h3.c b/drivers/clk/sunxi-ng/ccu-sun8i-h3.c index 6b636362379e..ca55c2ae999d 100644 --- a/drivers/clk/sunxi-ng/ccu-sun8i-h3.c +++ b/drivers/clk/sunxi-ng/ccu-sun8i-h3.c @@ -23,15 +23,21 @@ #include "ccu-sun8i-h3.h" -static SUNXI_CCU_NKMP_WITH_GATE_LOCK(pll_cpux_clk, "pll-cpux", - "osc24M", 0x000, - 8, 5, /* N */ - 4, 2, /* K */ - 0, 2, /* M */ -
  2. It's about this issue for sure. I'm yet confirm fix one way or the other yet though. Working on it.
  3. This remains a pretty serious issue. Has anyone made any pertinent discoveries? So far I've identified that boot time is unaffected, clock monotonic is getting incremented to the point of causing an overflow of the 32bit time number (hence 197x). Currently suspecting timer inaccuracy during frequency changes or something similar. Although not able to replicate in a lab at all (only in field).
  4. @janng0 Well done. Nice FEL mode solution, I too confirm it works remarkably well. 15V is sufficient too. Doesn't damage the other USB controllers either which is perfect. Confirmed on NEO & NEO Air devices. Now time to get secure images working.
  5. Where is the linking between the WiFi state and the LED defined? The NEO Core has an inconsistently on LED on the Core/Air image and I believe this to be the bug.
  6. Unfortunately legacy has it's own problems on NEO Core too (e.g one big one is that it takes >3m to boot, I suspect it's trying to get the wifi/bt up). To those who find this thread a workaround is to transmit 500ms of blank wav, then wait 3 seconds then start the actual playback. This appears to prime the audio circuitry (DAC?), perhaps it's power saving. Priming appears to last for 20-30 seconds.
  7. We are in the process of migrating from NanoPI NEO's to NanoPI NEO Core's as part of that we are moving to mainline NEO Air / NEO Core images. I noticed that audio playback is soft / fades in at the start of the file. This only seems to occur on mainline images. Thoughts?
