@guidol tested on Libre Computer Tritium with a Pimoroni PHAT DAC (PCM5102A), only changes needed: enable i2s@1c22400 (i2s1) change overlay to use i2s1 instead of i2s0.

Thanks @ning, I just wanted to pin a thread so we could get the conversation going, I'll take a look at Khadas and the upstream, hopefully avoiding the patchtastrophy that resulted from multiple patch sources last time.

With our Current moving to 5.7, anyone building it themselves should report anything missing/new/different/wanted here. Le Potato La Frite NanoPi K2 ODROID C2 VIM 1 USB OK OK OK OK OK REBOOT NOK OK OK NOK NOK SOUND OK OK OK OK OK HDMI OK OK OK OK OK Onboard WiFi NA NA OK NA OK

I did. ;-) I can't remember if we have a patch for that or not, my 5.4 image does have fan though.

OK. Boots, gets to desktop, plays the test video, sound via HDMI works, my RTL8821CU wifi was properly recognized. Only thing I see is no fan control, and the LED is just blinking at 1 Hz for no known reason. LibreELEC: same, boots, audio, etc. [edit] it did not recognize the wifi adapter. Now to dig up my Ugoos and stuff this on it.

I certainly can, it will have to be a bit later today, you should see my reply in the morning. Sent from my Pixel using Tapatalk

OK, now that I have these in-hand. The SD multiplexer board, for the 2x5 pin header, should that be a pass-through connector? Mine are soldered with a socket facing downward on both boards. Easy fix for me, maybe not for some of the others. ;-) All connectors are Mini-SPOX other than the SD card mini-board. the 1x4 pin header on each is populated, on the SD board it faces "up", on the serial board "down" I would assume one should be a socket. [edit] Well, I was not on the recent page when I wrote this, haha.

I'm not worried about the INA219. I don't want 0.3V drop across that resistor. Unless you out the feedback after that resistor, if the buck converter supports it... Sent from my Pixel using Tapatalk

I think I'll do a redesign, if anyone is interested. This one started out as a specific Tinker-based design, then kind of mutated. I found a 5A buck converter that might be nice. For shunt resistors, something more like 50 milliOhms as opposed to 100 would probably be better. The leads between the shunt and the amplifier need to be equal, and as short as possible.

@Nielo if you are willing to put in the work, https://github.com/armbian/build/blob/master/config/sources/families/imx6.conf I would guess there are a lot of similarities? It looks like a neat board, but I doubt the community of devs (~10 people) will have time/interest. I think it's neat, but I have no time to maintain something like that.

@guidol how bad do you want something like that, but say, just a bit more powerful? Sent from my Pixel using Tapatalk

I don't see any reason not to, the patchset is a lot of backported stuff anyway. I have a cranky Asus board here that kernel panics on boot with our 4.4 (sounds familiar), I might scab the device tree into something mainline likes and skip legacy for the moment. @Lanefu, we need to make sure the big patch isn't "undoing" any of the other patches, I got most of it cleaned up, but not all. Sent from my Pixel using Tapatalk

Yeah that must be a slip, 0603 is the standard package size. I need to go back and refresh that project to make sure there aren't any better options for parts now, thanks for the heads up. Sent from my Pixel using Tapatalk

:-/ I'll take a look around, and maybe we should ping @Neil Armstrong just to see, they don't have a C2 in their test lab, but perhaps he has an idea.

The thermal zones weren't added until after 5.4. Sent from my Pixel using Tapatalk

My XU4 with the Armbian kernel is fine with Plex and file server duties. Once I put it on the MC1's and started Einstein@home, it was all over. I'll have to give this a shot. Sent from my Pixel using Tapatalk

I got less time, my workload was very high before we were sent to work from home, and then the work didn't slow down, but everyone demanding meetings and phone calls increased. [emoji2357] Trying to avoid a burnout, I'm playing games with microcontrollers and easing back into fixing SBC's. :-) Sent from my Pixel using Tapatalk

I have not changed yet, I will though, I never got the other kernel to work reliably for more than a day during number crunching. Sent from my Pixel using Tapatalk

@vt19 let me know what the output of gives you, and I can take a look.

Hello @linsir, I've moved this over into the TV box discussion area, I think you'll find more info here.

The OPPs are from mainline, perhaps someone knows of a place where alternatives are defined? Or, I have seen varying versions of down clocking CPU when up clocking GPU. Sent from my Pixel using Tapatalk

I will test again, my last round of testing had working USB. Not to say something didn't change, there was another time that an unexplainable loss of USB happened that fixed itself after some time and upstream patches that seemed unrelated. Sent from my Pixel using Tapatalk

I will have to take a look, there shouldn't be any reason it wouldn't run. Sent from my Pixel using Tapatalk

Have you flashed the latest bootloader into the spi flash? These are available from links in the campaign, a lot of changes were made early on. Sent from my Pixel using Tapatalk
