EMC2 2.2.6 included the new hostmot2 device driver, with support for the Mesa 5i20 and 7i43 boards. Unfortunately, due to a bug in the driver, stepgen didn't work on the 5i20 (though it works on the 7i43). The problem has been fixed in TRUNK and in the 2.2 branch, but that only helps people who are compiling from source.
Users who install emc2 via the debian package (.deb) can get stepgen working on 2.2.6 by following this recipe: 1. Add "enable_raw" to the load-time config string for the 5i20. 2. Set hm2_5i20.0.raw.write_address to 0x2900. 3. Set hm2_5i20.0.raw.write_data to -1. 4. Set hm2_5i20.0.raw.write_strobe to 1. When the hm2_5i20.0.write function next runs, the steppers will start working. -- Sebastian Kuzminsky Computer Science for life, that's my direction Instead of b-balls, my homies throw exceptions -- MC Plus+ ------------------------------------------------------------------------- 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
