where and which iso are you downloading ? , this is important .
try the latest version of iso (2.7) , as your using Mesa their is no real need to , to take all notice of latency , this is just a test of many , take performance of the machine first
and perhaps use rt-preempt .
all configs will work across all versions from 2.6 onwards .
sorry ... today I've too load of work for make other test.
ò@cmorley .... this is a good things ...... I've not preference for wheezy or ubuntu ..... but the ld 10.04 is more convenient for my motherboard ....
@cncbasher .... i've downloaded the iso from linuxcnc.org .... with 2.5 version and than i've update first to 2.6 and than to 2.7 ..... there are other version of ubuntu 10.04 + linuxcnc2.7 iso?
today I downloaded new iso ubuntu10.04 + linuxcnc2.5 .... verify with md5sum (ok) ... installed ... run stepconf 1 time with parallel port ok! Using software source and synaptic I upgrade to 2.6.10 ... re.run the pc.... run stepconf 1 time with parallel port ok! ... re.run the pc ....Using software source and synaptic I upgrade to 2.7.1 ....re.run the pc.... run stepconf 1 time with parallel port ok! ... run PnConfig ... the same NOT APPEAR TB5 CONNECTOR ....not appear SS0 and SS1 page ... nothing about TB7 and TB8 .....
I-ve installed wheezy + linuxcnc 2.7 with american language ..... pcconfig run as aspected ..... but I-ve many error about serial comunication ... see demsg
i would take a guess , in that the 7i77 software is not up to date , did you update the 7i77 smart serial firmware also ?
as the softwarte has to match the newer hostmot2 driver , you may inadvertently be mixing old & new
you also have a realtime error
RTAPI: ERROR: Unexpected realtime delay on task 1 , this may be an issue ,
perhaps PCW can confirm the software is ok
[ 578.577388] hm2: loading Mesa HostMot2 driver version 0.15
[ 578.581600] hm2_pci: loading Mesa AnyIO HostMot2 driver version 0.7
[ 578.581671] hm2_pci: discovered 5i25 at 0000:02:00.0
[ 578.584228] hm2/hm2_5i25.0: Smart Serial Firmware Version 43
The firmware is fine (unchanged for a couple years)
The real time error is unexpected since there's only a 1 KHZ servo thread
and you would need at least a 200 usec latency to trigger the warning.
This likely indicates some problem with the PC/BIOS setup
This might cause the sserial errors (as could a 5V or 24V power supply issue)
