Re: Pi 4 Sigrok Pulseview not working

My suspicion is that the problem lies with the Pi4 hardware USB drivers. The Sigrok software communicates with a 8 channel Seleae logic analyser by streaming captured data over USB 2.0 high speed connection, my understanding is that this USB streaming is an unusual protocol, which presumably worked ...

Re: Pi 4 Sigrok Pulseview not working

It isn't possible from your report to determine whether the hardware (RPi4/RPi3+) or Operating System (Raspbian Stretch / Raspbian Buster) might be responsible. What would happen if you tried using the Raspbian Buster Operating System on the RPi 3b+ board? (It isn't possible, easily, to run Raspbia...

Re: Pi4 as Desktop computer

Go for a physical switch on a GPIO and use the [gpio27=0] conditional in config.txt to switch between the configurations. It's a useful little trick that I've been doing when testing out new kernels. If it doesn't boot then flick the switch to get back to a known good system, update the dodgy kerne...

Re: Pi4 as Desktop computer

And as far as overclocking, I consider myself lucky to have found at least one limit. AND - I am prepared to have to replace the Pi 4 if I kill it. And I do NOT plan to whine and complain and beg for warranty replacement i do! Some GIMP operations. Now all I probably should do do is write a little ...

Re: Pi4 as Desktop computer

It is able to run about everything fine at 2 GHz with over_voltage=5/6 and official power supply. Just not this. It shows the PMIC is a tight fit when not even 1.75 GHz works. [Citation needed].

Re: Raspberry Pi 4 temperature

Being inaccurate is ok (just) , blatant lying is unacceptable. You clearly know very little about the Pi. 1. Not been around for 8 years. 2. Always had HDMI. 3. Unless you work for either Pi or Broadcom, your suggestions were probably not even noticed. If indeed you actually made them. And I'm pret...

No, nope. The correct theoretical performance of the GPUs is as follows: VideoCore IV @ 250MHz: 250 [MHz] x 3 [slice] x 4 [qpu/slice] x 4 [processor] x 2 [op/clock] = 24 Gflop/s VideoCore IV @ 300MHz: 300 [MHz] x 3 [slice] x 4 [qpu/slice] x 4 [processor] x 2 [op/clock] = 28.8 Gflop/s VideoCore VI @...

Re: Pi4 as Desktop computer

For USB boot, use a SD card to redirect boot to the USB device you want to boot from. The only difference from native USB boot is you need a SD with with just bootcode.bin on it and some config. I have seen a few posts suggesting this as the current solution for USB booting but does this actually w...

On other side my Raspbian resolution stayed on 1920x1080, 60.00Hz. Not sure if Raspbian buster resolution means something but this one fits nicely to my TV screen, ...

Hi John,
Yes I had done the firmware update as well, I just copied and pasted every command in order, till I finished. :-)
I strongly suspect it was caused by the fact that my Stretch was an upgrade from Jessie, not a straight Stretch installation.
