Re: Raspberry Pi 3 Model B+ - Freeze during installation?

Cool, sounds like a test escape. All Pi's get tested at end of production but if the failure is only intermittent it may be missed. Glad the new one is behaving better. I am deeply impressed of the work you all done with the Raspberry and for a noble cause as well. The little amount of work I had t...

Re: Raspberry Pi 3 Model B+ - Freeze during installation?

I exchanged my B+ board today and got a new one. Now everything seems to work. I have compiled my game twice without the B+ freezing and on my previous B+ board it always freeze.

I will run some more tests and see what happens but so far it looks very promising.

Re: Raspberry Pi 3 Model B+ - Freeze during installation?

Thanks. Is that the newer 2.5A official PSU or the older official 2A PSU? (I discovered I was still on the 2A, although I too haven't see any under voltage warnings in dmesg plus actual measured voltage was good even though I'm seeing card timeout messages etc in dmesg.) Hi Julie, I have the newer ...

I am actually using the same SD Card on both my 3B and 3B+. I just rm the build directory and re run my compilation test. I...

Re: Raspberry Pi 3 Model B+ - Freeze during installation?

The card only contains the image and gcc 7.3.0. When I compile gcc 7.3.0 on my 3B+ it freezes when I use exactly the same SD card and compile gcc 7.3.0 it works. When I tried to install something on the 3B+ it freezes when I install exactly the same package using apt on the 3B it works. I was runnin...

Re: Raspberry Pi 3 Model B+ - Freeze during installation?

I have now installed the Raspian 4.9 image directly to and SD card and during compilation of GCC 7.3.0 my 3B+ freezes exactly as before and my 3B works as a charm. My conclusion is that the 3B+ hardware is defect. Anyone has any other idea?

Thanks,

Re: Raspberry Pi 3 Model B+ - Freeze during installation?

Refresh your SDCard with latest bootcode/firmware. The one you've got is too old to boot a 3B+. The installation boots just fine on the B+. I then select Install and see all of the nice installations screens but after a while the B+ freezes. If I do the same thing on my B the installation completes...

Re: Using usb bluetooth adapter along with onboard bluetooth in RPi3B

The built-in adapter both in 3B and 3B+ cannot drive bluetooth keyboard, mouse with the wireless network turned on. My experience is that the keyboard becomes very sluggish. The solution was to disable the built in bluetooth adapter and use an external one which works perfectly.

Re: Raspberry Pi 3 Model B+ - Under-voltage warnings

Something is really wrong with the hardware. I compiled gcc 7.3.0 which worked fine. When I did make install 3B+ hanged in the same way as when I tried to install the raspian. I have tried two different SD cards with the same result, everything works with 3B hardware.
