Re: Mesa 19.3.2 available for testing

There are reports that it can make some thing slower, and not support as many overclocking options, or lock up:

Can anyone confirm?

Re: Haupauge DualHD (em28xx) driver broken. Kernel spam "write to i2c device at 0xcX failed with unknown error" on RPi4

Still no joy - I downgraded the EEPROM for the USB3 controller, I tried increasing the PCIe etc. values.
Still just errors with the same write error.

Re: Haupauge DualHD (em28xx) driver broken. Kernel spam "write to i2c device at 0xcX failed with unknown error" on RPi4

I've seeing this on a PCTV 460e - same errors in the logs, very unexpectedly poor performance of the device. The same RPI4 can handle several DVB-T sticks / hats and stream no problem but the above USB2.0 stick doesn't seem to be doing what it should and throwing lots of errors. I have an RPi3 which...

Re: ~rpt1 in some raspbian packages?

Not sure - the rpt version has a lot more dependencies on things like libavcodec I imagine it's modified for acceleration, however it also misses out transcoding acceleration that's available by using omx-player. There are instructions elsewhere on the net to recompile tvheadend to enable this on RP...

Re: USB - the Elephant in our Room

I don't understand the grumblers. Because, for some things, the USB DOES NOT WORK. Simple as that. No matter how much power you throw it at, what firmware you use, what distro you run, how short your cables are, or any other factor whatsoever. I can provide examples of both keyboards and 3G modems ...

Re: USB packet loss.

Bad news for Raspberry Pi users today: That's okay. My RPi is still sitting in the box waiting for something practical to work on it. Given the single (not unreasonable) project I bought it for has been stymied on several levels, it can just stay in the box. A lesson to myself in why I don't preord...

Re: Powering via GPIO

I'm not certain, but I believe those pins (or at least two of them) merely expose the whole-board power rails that are used for everything else (thus putting power down them is equivalent to plugging something into the power socket directly). I think they also feed TP1 and TP2 at some point which do...

Re: USB packet loss.

As far as board-killer is concerned, I don't expect that. My understanding is that there's a pile of electronics between the USB port of the Pi and the Arm. First off is the 9512 chip. There may be a problem with that, which would be difficult to get round. But it would have been found before now s...

Just eliminated the board as a factor - plenty of other 2Gb cards work fine on the same RPi. Just this card that doesn't, and it does it enough that although I wouldn't say "every single time", that you should be able to spot it without too much testing (seems to happen more when the board...

Re: Mouse and keyboard over GPIO?

one solution would be to use a parallax propeller micro controller, which has eight CPU cores. Seriously? A 40-pin DIP chip which (bare) costs almost as much as the RPi itself? Seems a bit overkill to me. I think the Arduino board linked in above was more sensible - it did a lot more, in a lot more...

I think this might be the cause of a problem I'm noticing too. I'm using an Huawei E160 3G USB modem on the RPi. PPP etc. works as I expect. But at random intervals, PPP says that the modem "hung up" (which it didn't, looking at the logs of the data) and cuts the connection. Via minicom, A...
