I'm betting the updates added a new version of the kernel and now the realtime kernal is not loading when you start the computer.
That seems to be the error message.

Can you see the screen to select kernels on start up? I forget at the moment how o get it to show if you can't...

as for the read me could you explain more. The read me will tell you the pin numbers of the 5i20 but not the daughter boards.
though the readme and the dmesg should agree. can you post a copy of each?

Are you using sserial cards? the read me hasn't been updated to include them.

Thanks

hmm now that I think of it pncconf will let you know if the kernel version is wrong if you try to test.
did you try any live tests in pncconf?

Old machine configurations generated under 2.4 do not run under 2.5

Can not get any other out put from EMC2 until the problem is resolved..


Am trying to revert to version 2.4.7
Need to get the machine running


The readme file shows All pins exported by 5I20 on P2,P3 and P4 5i20 headers.

The pin report when EMC2 starts and is made available through dmesg shows ONLY pins on P2 header.

I'm sorry the transition has been so difficult - it usually isn't.
Sounds like a real problem as dmesg should always report all the pins of all the headers.

dmesg is not giving much info as to the problem either....

i wonder if this has something to do with renaming - I see alot of references to emc2 and most were changed to linuxcnc.

I'm sorry I am not sure what to recommend.
I have heard of no problems with buildnot linuxcnc.
Hopefully someone else will shed some light.

Chris,

Thanks for your time and effort, all your time and effort.

For the time being I shall revert to 2.4.7.

I need to get the machine up and running for the morning.
We are fabricating printed circuitboards and are now suppoerting a local R&D facility fabricating boards with 3D rf structures including cavities within a multilayer structure.

Have been down for a few weeks with servo problems so now really need to get the gear up and running
