Re: Raspberry pi 4 4gb no HDMI output

Hi ! Depending on how the green led is blkinking, (like booting) this can either look like an HDMI problem or look like it doesn't boot anymore - but hopefully if leds are working it cannot be completely dead. Is it answering to ping requests? (or even more, available using SSH or VNC?) If not, did ...

This is something you can probably see too if you read your SD card with dd for example. And please stop telling people to throw their SD ...

Toss it. Get a fresh 32GB card and stop mucking about trying to flog a dead horse. Years ago you told me to trash a brand new Samsung SD card just before somebody told me "try rpi-update" and then the problem was solved. Also, on most card, you can use "blkdiscard /dev/mmcblk0" This will play some ...

SWAP on Raspberry Pi / SD = AUTOCRASH

I wonder who had the brilliant idea to enable a SWAP system by default on Raspbian for the Raspberry Pi, which runs on SD cards. This is a perfect way to ensure that the device will get completely stuck for hours as soon as something is trying to use a little bit too much of RAM, instead of just int...
