Raspberry Pi 4 mmap
Followed above suggestions to create a static IP - followed a couple of tutorials (both similar in that they used dhcpcd). That didn't fix the problem if I did things correctly.....
After a couple days of trial and error frustration I created a new image on an SD card. Before running pnconf I disabled wifi (didn't do that originally) and set ipv4 to 192.168.0.1/16. In first try that failed was set with /24. Disabled ipv6. Then ran pnconf using settings I know work on my system.
And voila everything worked.
But after shutting down and powering up - back to same error as before. Nothing seemed changed in the IP setup. Double checked address of mesa7i76e in the hal and ini. All looked the same but no go.
Will try another round of same tomorrow but sure would like some insight into what is wrong and or fragile in the process.
This is following the suggestions in the hm2_eth manual.
# interfaces(5) file used by ifup(8) and ifdown(8)
# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'
# Include files from /etc/network/interfaces.d:
iface eth0 inet static
I did this while running running remote desktop over the on board WiFi. Probably not the best thing. When I actually start using LinuxCNC I will have a dedicated display and keyboard.
I'm using the on board LAN to connect to the 7i92. I've heard that the onboard WiFi can increase latency. I still want internet connectivity.
So, the question is, what's the recommendation for a USB LAN dongle? Traffic on this LAN connection should be light, and if necessary, unused while LinuxCNC is active.
Also the gpio driver from MX_Master has the reset function, allowinfg doubleStep for the OrangePi that he targeted. Can this code be adapted for RPi ?
