I've used the rpi-update utility to get the latest kernel and firmware to see if it addresses some USB errors. Following the upgrade the 'OK' LED is off most of the time and occasionally flashes on. The Pi appears to operate normally. I've done this with two SD cards, each behaves the same. If I flash them back to the state I had before the update, the LED stays on.. My installation is fairly standard, just the April Debian and a VNC server. The version details after update are :
Linux version 3.1.9+ (dc4@dc4-arm-01) (gcc version 4.5.1 (Broadcom-2708) ) #101 PREEMPT Mon Jun 4 17:19:44 BST 2012
Has anyone else observed this behaviour? Should I be concerned?
Re: OK LED off most of the time following rpi-update
Mine is the same. I think that light is meant to flash for SD card access so that makes sense.
If I have no wired ethernet then I have the Red Power LED on solid and occasional flashes on the OK LED. All other LED's being off.
If I have a wired Ethernet connected then I get the three LED's associated with that coming on as well (2 green and one yellow) - ending up with quite a light show

Re: OK LED off most of the time following rpi-update
That is correct. I had always intended the LED to be lit when SDCARD was being accessed, but the initial kernel had that inverted.
Occasional flashed on (typical from sdcard) are much more visible than occasional flashed off.

Re: OK LED off most of the time following rpi-update
Thank you for the information, I'll trust this update then. Perhaps 'OK' isn't the best legend to have on the silk screen. I'm sure other users will also interpret the absence of light as signifying 'NOT OK'dom wrote:That is correct.

It's not as bad as "10M"

Re: OK LED off most of the time following rpi-update
You get the same if the file system is copied to a memory stick. On boot-up OK flashes once, briefly. But after that the SD card is not being accessed so OK does not light up again.

Someone tell what rpi-update is please?

It's way of keeping your Pi up to date with the very latest firmware/kernel patches. Best explained heredpawson wrote:Someone tell what rpi-update is please?

Having run it I get
Using SoftFP libraries
/opt/vc/sbin/vcfiled: error while loading shared libraries: libvchiq_arm.so: cannot open shared object file: No such file or directory?
Suggestions please?

It does that for everybody apparently. It can be safely ignoreddpawson wrote:Having run it I get

Thanks.
Last night the ca-certificate failed to download (or be found, one or t'other). Is this resolved now?

Re: OK LED off most of the time following rpi-update
@texy, Have you done a "sudo apt-get update" recently? I understand things are moving quickly in the Debian world at the moment.
Re: OK LED off most of the time following rpi-update
No, not since last night
