Greetings
I have run a real machine and made chips with the BBB and MachineKit package. And very impressive and promising it is even with a 750 kB engraving job. Trying to get beyond the basic integration shows my poor Linux fundamentals :=( (a) Having used the bootable SD card I can remove it and boot the original system from the BBB eMMC but other SD cards will not show up under it in a "df" listing. I wanted to make a new bootable SD to work on while also retaining the known simple configuration that works. Is this change to original system behaviour expected and if so how is it reversible? (b) I am bemused at where the magic numbers connected to steppin and dirpin in HAL come from (e.g. the comment the actual pin used and 0x4c make no sense to me: #P8.43 PRU1.out2 setp blah blah .stepgen.00.steppin 0x4c I have looked for a pattern with this BeBoPrBr example and all the tables including considering the 0x800 bit and the excess 32 coding for PRUs but cannot see any pattern. I want to add another stepgen to drive the machine spindle. The B axis seems in place in the .dts file but what goes in the HAL? (c) Straight Linux problem: I cannot work out how to Mount USB sticks in the running system under XFCE/Thunar except logged in as root. Thunar says Not Permitted and unlike under Gnome you cannot run things like Thunar or medit with sudo from a Terminal. Google was not my friend on this occasion giving lots of recipes in fstab but no explanation of principles. (d) Similarly I can only shutdown/restart Linux by logging out of linuxcnc and logging in a root as the buttons are greyed out when user linuxcnc. (e) finally and this may be a step too brave at present, I wonder if anyone has tries/succeeded to run the filesystem off a USB drive (probably a harddrive) using pivot root. The hope was to get better performance, particularly in development systems as I would like to install some user Comps.
