rpi-update breaks the load. It somehow deletes the start.elf file.
When did you update? This should have been fixed at 12:36 today. Any updates after that point should include the start.elf file.

Re: Moving Linux kernel to 4.19

Just added start_x=1 to the config.txt and then updated to 4.19.55. And now the system boots. The start sentences text at the startup however are now rather big. Putting the start_x=1 on a other location in the config.txt does not seem to help. Doing another rpi-update should get the missing start....

Do you know why they don't they work on the Pi4 ? I've just found that my own openGLES2 code doesn't work any more but I've not yet looked what has broken it. When running with the legacy GL driver you needed proprietary setup to create a surface for GL to render to (the dispmanx calls). With the a...

latest update tag 4.19.55, Rpi2B won't boot.
Is start.elf present? There was a bug in rpi-update that should be fixed now.
Add start_x=1 to config.txt and see if it boots.

Re: Raspberry Pi 4 Thread - general discussion

Some DVB-T TV channels use MP2 (e.g. in Sweden) and this could mean that playback is worse on Pi 4 B than on Pi 3 B+. I have not bought a license key for MP2 so I'm not using the hardware decoder anyway. I use e.g. VLC to watch TV using TVHAT on Pi 3 B. Denmark, which is close to where I live, uses...

In your opinion do I need to check something?
Nope. Minor kernel bumps rarely cause issues so you shouldn't expect a problem, but there are rare exceptions.
The major kernel bumps (e.g. 4.14->4.19) have a higher chance of issues, but they seem to have been resolved now.

As of 1.35pm, 6 May 2019, "sudo rpi-update" gives the error "Invalid git hash specified". Tested on RPi Zero W and RPi3 running stock Raspbian.
It's working here. May have been a temporary github issue? Does it still fail?

I am not sure whether this is the driver issue or rather Xorg issue, but after enabling KMS fake driver (dtoverlay=vc4-fkms-v3d), the Xorg startup is much slower.
Can you confirm this occurs on a fresh raspbian install?
Assuming it does, reporting here may be best.
