Re: Pi4 Not booting, SDcard/HDD works fine on Pi2

Having got my Pi 4 to run - not all USB-C power supplies are compatible with the Pi 4 it seems - by getting an official PSU, my Pi 4 also refused to boot to desktop with occasional flashes off the boot screen etc. I just did an 'rpi-update' to the latest (July 4th) kernel etc and it is now working f...

Re: USB Type C of Pi 4 model B

The two cc pins on the USB-C power are connected together to a single pull-down rather than a separate pull-down on each so that some USB-C power supplies do not output anything to power the Pi 4 however the Raspberry Pi USB-C power supply does not have this problem?

I run Raspberry Pi desktop with VMWare successfully. Have you installed it to a (virtual) hard disk or just booting from the image. I think the only problem I had was the display resolution being reset to the default.

The SD card needs to be class 10 because the Windows OS times out with slower cards. Are there any SD cards that a...

Or something like it. The power supply on mine failed because the two parts of the transformer in it were not glued together. Also there was no input filtering causing interference on the radio!. A replacement proper power supply and it works fine!

Don't assume that any old cable is suitable.

To adapt the old adage:

Measure (with a continuity tester) twice, plug in once ;)

Specifically pin 34 on the connector is grounded on the motherboard (blue) end of the cable.

Before following this recommendation please review this http://www.raspberrypi.org/phpBB3/viewt ... =28&t=9819 discussion. Sorry Dave, it is not really suitable due to it's power consumption from the 5volt line on the HDMI port. Unless this model has significantly reduced consumption?
