Hardware issue overheating while booting and fail to boot

[dukla2000]

Looks like a death in action. But ...

The heatsink getting warm indicates to me it is alive which is promising. Running warmer than "normal" because no OS has loaded to play withh the governor.


Is the LAN plugged in - are you getting any lights on the RJ45 socket?

Can you try SSH across your network (just to try find signs of life)? Would assume white LED and HDMI are bust which is barely plausible but ...

Have you got eMMC plugged in? (Or anything other than HDMI, keyboard?)

Only straw to clutch at is you have written to the SPI so the boot is looking for bootable USB. Really long shot this and unlikely!! Normally (as you know) white LED behind Reset comes on as OS starts to load, a few seconds after power on. (This reminds me it is possible to jumper some PI2 pins to clear/override this - must find & add to wiki!)

You could try monitor via serial cable (on the assumption you have one).

You could try playing with the Recover button (as per Ayufan - see link from wiki here.)
