The "invalid cookie" error indicates the following: The driver sent the firmware to the FPGA; the driver thinks the FPGA accepted it; the driver tried to verify the firmware running on the FPGA by reading a certain location; but the value was not the expected value. This probably means the FPGA is not running the firmware the driver expects, or the communications between the driver and the 7i43 is getting garbled somehow (maybe bad cable). Please verify the integrity of the firmware file by running "md5sum SV8S.BIT", the output should be: 1380a9b6afa6f93d4d57e2d59a632efa SV8S.BIT The other 7i43 BIT files have these checksums: cb3965e93765d02f08792eda93e6e0c1 SV8B.BIT e602bc3da57c69936a99aa523152d124 SVST4_4B.BIT 6c20162fe16be55191119788a2bd4bf6 SVST4_4S.BIT fcc06da0350919668613d4f661cfe016 SVST4_6B.BIT Do you get the same "invalid cookie" error with the other firmware files? How long is your parallel cable? Is it rated for IEEE 1284?

For it to work you need to have the Linux parport driver loaded, then when you make a mesa7i43 object you pass parport_id="parportX" to the constructor (where X is the number of the linux parport device). It defaults to parport0 if not specified. > Here's the hardware: > 0x378,0x0778 parport0 > 0xd000,0xb800 parport1 (on-card port) > 0xb400,0xb000 parport2 (ribbon cable port) > 7i43 powered from USB, no USB drivers in kernel. > > software: > debian sid > Linux x2 2.6.22.081012.1 #1 PREEMPT Sun Oct 12 13:16:18 PDT 2008 i686 > GNU/Linux > kernel /vmlinuz-2.6.22.081012.1 root=/dev/mapper/debian-root ro > acpi=off pnpbios=off isapnp=off > RTAI 3.6-cv (closure version) > Emc2 trunk current > > Commands: > /etc/init.d/realtime start > sudo echo 4 > /proc/rtapi/debug > halcmd -V loadrt hostmot2 debug_idrom=1 debug_module_descriptors=1 > debug_pin_descriptors=1 debug_modules=1 > halcmd -V loadrt hm2_7i43 ioaddr=0x378 ioaddr_hi=0x778 epp_wide=1 > 'config="firmware=hm2/7i43/SV8S.BIT num_encoders=3 num_pwmgens=3 > num_stepgens=0"' debug_epp=1 > Or > /etc/init.d/realtime start > sudo echo 4 > /proc/rtapi/debug > halcmd -V loadrt hostmot2 debug_idrom=1 debug_module_descriptors=1 > debug_pin_descriptors=1 debug_modules=1 > sudo halcmd -V loadusr -w bfload > 7i43:0x378,0x778=/lib/firmware/hm2/7i43/SV8S.BIT > halcmd -V loadrt hm2_7i43 ioaddr=0x378 ioaddr_hi=0x778 epp_wide=1 > 'config="num_encoders=3 num_pwmgens=3 num_stepgens=0"' debug_epp=1 > > Note: Double quotes in hm2_7i43 command took me some time to figure out, > as the config modparam single quotes were getting stripped by Bash.

Your suggestion about the quotes for the config modparam is good too, i'll add that to the manpage as you suggest. -- Sebastian Kuzminsky Distances obtained as the speed of light multiplied by a cosmological time interval have no direct physical significance. <http://en.wikipedia.org/wiki/Observable_universe> ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
