Can you enable "raw mode" and see if the driver it writing the correct step rates to 0x2000, 0x2004, 0x2008? (The addresses come from this file: http://git.linuxcnc.org/gitweb?p=hostmot2-firmware.git;a=blob;f=regmap;h=b3a 2a77c27de0c71278dc910992efeddd7deb577;hb=HEAD ) These steps will help to determine if the problem is in the driver code or the FPGA code. Gents, my apologies for wasting your time. When I began peeking HAL config I found that hm2_5i23 parameters were not as defined in the ini file, and by poking maxvel and maxaccel quickly confirmed there is not a problem on the 5i23, nor with driver parameter passing. Let's just say I don't recall overriding parameter passing between ini and hal configs by presetting fixed values for maxvel and maxaccel in the hal file! All now working as expected. ------------------------------------------------------------------------------ November Webinars for C, C++, Fortran Developers Accelerate application performance with scalable programming models.
