Hi. i'm a newbie on the forum and was hoping someone could help me.
I have installed a copy of Slackware on a RPI 4B and have been using it as a remote SDR machine for some weeks.
Recently it died and failed to reboot and I now have it on my desk to troubleshoot the issue.
On applying power to it the red power led comes on and i get one green flash from the ACT led and that's all. It doesn't attempt to boot, and the HDMI attached screen reports no signal found. It's obviously failing very early on in the boot sequence.
I am booting from a SD Card and I have re-flashed it with the Slackware / SDR image which was working but to no avail. I also tried a brand new SD card but no luck.
Thinking that the EPROM may be corrupt I attempted to re-flash that using rpi-imager and a new SD card but when I inserted the card and powered up the RPI 4B I got exactly the same result - a red power light and one green flash from the ACT led and nothing else.
I subsequently tried to re-flash the EPROM from a USB stick with exactly the same result.
I'm beginning to think that my RPI 4B is bricked. Any advice or other suggestions would be much appreciated.
Thanks, MD.
