I understand you are running your self-compiled kernel. This could be part of the problem. It seems the component loads work fine but the RT thread immediately exits which points to this cause.
first, try the kernel supplied with the SD image. It is next to impossible to verify you got a working kernel and I see no reason to use a self-built one, however that was done. Then, can you post the following: - output of uname -a - output of dmesg after boot, and after starting linuxcnc. in case you changed anything in the config, please push that to github. > Am 02.08.2016 um 09:04 schrieb Chen Cheng Xi <[email protected]>: > > Hi, I solved BB-LCNC-BEBOPR can not loaded issue as below: > cape_disable=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN,BB-BONE-EMMC-2G > > ubuntu@arm:~/machinekit$ linuxcnc > MACHINEKIT - 0.1 > Machine configuration directory is > '/home/ubuntu/machinekit/configs/ARM/BeagleBone/BeBoPr' > Machine configuration file is 'BeBoPr.ini' > Starting Machinekit... > io started > halcmd loadusr io started > Loading BB-LCNC-BEBOPR overlay > Loading cape-bone-iio overlay > BeBoPr.hal:28: module 'hal_pru_generic' not loaded > Shutting down and cleaning up Machinekit... > <commandline>:0: error unloading realtime module 'hpg': rc=-1 > <commandline>:0: unload: 'hpg' not loaded > > <commandline>:0: unloadrt failed > <commandline>:0: error unloading realtime module 'hpg': rc=-1 > <commandline>:0: unload: 'hpg' not loaded > > <commandline>:0: unloadrt failed > Cleanup done > Machinekit terminated with an error.
