VCHIQ Error on Rasberry Pi 2

[chrisrios88]

Hello,

I had an existing image from my Raspberry Pi B that I upgraded and got running on the Raspberry Pi 2, so it boots fine without a problem (I primarily use it to run Omxplayer)

When I try to run omxplayer I get an error:

* failed to open vchiq instance

A grep of dmesg shows:
dmesg | grep vchi
[ 1.713870] vchiq: vchiq_init_state: slot_zero = 0x8ec80000, is_master = 0
[ 1.723651] bcm2835_vchiq 3f00b840.vchiq: failed to set channelbase
[ 1.732203] vchiq: could not load vchiq
[ 1.737952] bcm2835_vchiq: probe of 3f00b840.vchiq failed with error -1908864768

uname -a:


Linux FL-SLCC1-PI 4.1.7-v7+ #815 SMP PREEMPT Thu Sep 17 18:34:33 BST 2015 armv7l GNU/Linux

Kind of at a loss here because I can't find anything on the errors I'm getting, everything I've found is related to /dev/vchiq but my problem is that doesn't exist since that's created when the VCHIQ module loads properly (which it doesn't)

Any help would be appreciated. Thank you!

Hi, I was trying to run latest kernel (from 4.2.y branch) and had a similar error but different error code.
Resolved by updating firmware to the latest version from https://github.com/raspberrypi/firmware .

Hope this helps

Thanks! Is there an easy way to configure rpi-update to use the 4.2.y fork instead of 4.1?

Not until the RPF folks switch over from 4.1.x to 4.2.x.

I have essentially the same problem except for the returned error code. I updated the firmware but that didn't fix the problem. Is that all you had to do to fix yours?

I posted the specifics of my problem here:
Camera no longer works, vchiq seems to be the problem

Hello jward,

For me yes, all I had to do was updating the firmware.

The raspberry pi official touch screen display did not work with kernel 3.18 I was running and I updated to the latest kernel 4.x. First I could not get any graphical applications to work. There were similar messages in the log as in the first post of this thread, but different error code. There was no /dev/vchiq. Once I had updated the firmware the error had gone and everything was working OK.
