Can anyone tell me why all of a sudden I cannot boot any Linux OS image yet it will boot and run my RISC OS SD Card without any problems? I have already looked over the troubleshooting etc at http://elinux.org etc.
It seems that I can no longer boot any Linux Image (that were fine before) yet I can still boot from a RISC OS SD Card. This is on a previously fine 512MB Raspberry Pi. The same SD card that wouldn't boot (a Sandisk Ultra 8GB) in this, boots fine on my 256MB Raspberry Pi. Yet I have tried re-imaging from known working images to either this card or a Kingston 8GB SD card and the Red Power LED glows without so much as a flicker from the Green LED.
The last thing I did with my Pi today was an update/upgrade to whatever the latest updates are and was trying to transfer a photo via Bluetooth when the Desktop froze. I waited to see if would 'unfreeze' but realized that pulling the power was going to be the only option. I mention this in case there is a connection, although why it would affect another known working 8GB card is beyond me.
That is when it wouldn't boot. I naturally thought I had corrupted the card, so used my other working SD card to re-image from a known working copy of Raspbian but still no Dice. Even Arch Linux will not boot now.
I thought about imaging RISC OS onto the card to see if the card would boot with this, but remembered it doesn't seem to work with 8GB cards. We'd already tried that before even on a friends Raspberry Pi.
I am baffled as to why it now has a problem with booting Linux and not RISC OS. If it hadn't have booted from the RISC OS card I would've assumed my device had simply died for good.
I even tried the bootcode.bin replacement which didn't work. This didn't surprise me though as I would've thought I'd have had problems booting before now.
The fact that it boots RISC OS at least gives me hope, but what on earth would now suddenly make it not even attempt to boot Linux?
