Re: Fixing the Pi 4 usb C issue by hand

I thought so too. Especially from what I would expect to be a high-volume seller.

On the other hand, maybe they ordered a large lot, and thus have a lot of old stock. At any rate, I exercised my soldering skills (and microscope) doing the mod, and it all worked out.

Not necessarily true. I bought mine recently from Adafruit, and it was not the new version.

Re: Fixing the Pi 4 usb C issue by hand

I don't know if they're all marked. But I wanted to be able to use an Apple laptop power supply, and that does work with this mod. I didn't try before doing the fix, but those were called out as ones that wouldn't work.

I'm interested in the current state of this application as well. I need to read BWM-specific codes, and the code readers for brand-specific codes aren't cheap.

Re: Fixing the Pi 4 usb C issue by hand

Have you confirmed that you even need to perform this mod? By now, you should not be able to buy a Pi without the fix applied from new. Yes, as noted above, there's a component by the SD slot. And apparently no, you can't expect to receive a 1.2. Adafruit (rather huffily, it seemed to me) declares ...

Re: Fixing the Pi 4 usb C issue by hand

My Pi 4 just arrived from Adafruit today, and unfortunately it's the old version (2 GB model). So I decided screw it, I'm going to do this mod before I even fire it up. I will say that the only thing that made this task possible was an inspection microscope and some very, very pointy tweezers. At th...

Re: Any word on the missed-keystrokes/repeating keys problem

I tried using an external power supply. Then I tried using both at the same time.

Then I tried powering the Pi using only the dock but with the Apple keyboard, and that works. So power does not appear to be the problem.

Raspivid locks the Pi up after every couple of executions

Hi all. So far I'm pretty disappointed with the camera. Aside from frequent visible glitches in both the preview and the recordings, raspivid locks up the Pi after every couple of runs. I was just executing it with various effect and exposure-mode options (one at a time) to see what they did, and I ...

Thanks for the replies. And I have updated Raspbian. I was using a Motorola Atrix dock, which is simply a USB keyboard, HDMI monitor, and battery in a laptop-looking clamshell; it makes a really cool monitor and keyboard combo for the Pi. Or, at least it would, if the keyboard were functioning prope...

Re: Raspivid recording quality poor and glitchy

I'm getting glitches in the preview when recording, so I don't see what this would have to do with the SD card. The glitches are there when I play the file back. Also, a file-copy test to the SD card shows write speeds of 16 megabytes per second or so. I find it hard to believe that it can't sustain...

Any word on the missed-keystrokes/repeating keys problem?

I've updated my Raspbian, and my Pi is still essentially unusable because of missed keystrokes and repeating keys. I've tried swapping the port that the keyboard is plugged into, and even dual-powering the thing with an external power supply and battery power through a dock connected to the USB port...

I moved the keyboard to the bottom USB port (closest to the board), and the problem still happens.

This thing is useless as it stands.

Hi all. I'm often asked to calibrate friends' and family members' TVs. I don't have a Blu-Ray calibration disc yet, but I was thinking that a Raspberry Pi could be an even better calibration tool.

Re: Making Pi discoverable to Macs with Avahi isn't working.

Ha! Well, now my keyboard drops or repeats characters at random, another longstanding known bug. It's way worse than the Avahi problem, since the Pi is nearly unusable at this point.

I guess I can more easily shell into it now with a computer that works, so it's a trade-off...

Hm, more than a year later and this problem still exists. I've updated to the latest firmware, and I'm getting missed keystrokes and endlessly repeated characters at random but frequent intervals. Test points show that the voltage is 4.89.

Since the segmenter only starts new segments at a keyframe changing -g allows using different least common mul...
