Subject: [Emc-users] 7i43 Invalid Cookie message
Morning all,
A problem on my machines has appeared during recent updates; it does not stop
either of my machines working but seems to indicate a firmware load error.
I'm using 7i43's on 2 seperate cnc's, first a standard mill, second a router.
2 seperate PC's, different hardware, different parport cables etc. The error
message does not affect the function of either machine in any way and they
continue to work fine.
On either machine I see in dmesg:
[ 798.554352] hm2/hm2_7i43.0: IO Pin 047 (P3-47): IOPort
[ 798.554402] hm2/hm2_7i43.0: registered

[ 798.556450] hm2_7i43: failed to clear EPP Timeout!
[ 798.556455] hm2/hm2_7i43.1: error reading hm2 cookie
I'm using the svst4_6.bit bit file. When loaded to the card using the
mesaflash tools, the firmware image loads perfectly and the pin assignments
can be read back from the card with no errors reported. I did see on the list
that there were previous issues with reading back checksums from other
similar bitfiles, just wondering if my issue is something similar. I've tried
setting epp_wide mode to off and it made no difference. I've verified on both
machines that EPP1.9 is configured.
If anyone can shed any light on a possible fix it would be appreciated.
The machines configs are both similar to:
.INI
[HOSTMOT2]
DRIVER=hm2_7i43
BOARD=7i43
CONFIG="firmware=hm2/7i43-4/SVST4_6.BIT num_encoders=3 num_pwmgens=0
num_stepgens=5"
.HAL
loadrt trivkins loadrt [EMCMOT]EMCMOT servo_period_nsec=[EMCMOT]SERVO_PERIOD
num_joints=[TRAJ]AXES loadrt hostmot2
loadrt [HOSTMOT2](DRIVER) config=[HOSTMOT2](CONFIG)
Thanks and Regards,
Paul.

What update did you do? (what version of LinuxCNC are you running)
The messages seem to indicate a problem in the driver, It looks like it found
and configured the card, then tried again.
