-- > Sebastian Kuzminsky > Dear Sebastian, Thanks for your suggestion. I am modifying the PMAC PCI driver so that it can run under the user space LXRT of RTAI . PMAC is a motion control card from Delta Tau Inc. Considering PMAC itself is a CNC system, I am not going to modify it into a HAL driver for the moment. However, the RTAI real time capability is needed. PMAC PCI has a dual port RAM (DPRAM) which be used as a fast communication channel with a PC. I have an error in loading the real-time PMAC PCI driver. The main change is the addition of " reset_rt_fun_ext_index". I have tested the driver successfully in lower version linux-image-3.4.55-rtai-2. However, when I update the rtai to linux-image-3.4-9-rtai-686-pae, it shows the folllowing error. pmacpci_rt: no symbol version for reset_rt_fun_ext_index pmacpci_rt: Unknown symbol reset_rt_fun_ext_index (err -22) I installed the RTAI following the steps in <http://linuxcnc.org> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?UpdatingTo2.6 Therefore I do not know what is the version of RTAI. Anyway this error happens when updating RTAI from 3.4.55-rtai-2 to 3.4-9-rtai-686-pae. I uploaded the whole folder of the PMAC PCI driver http://pan.baidu.com/s/1ntt6KUd Xue-Cheng XI ------------------------------------------------------------------------------ Want excitement?
