Hello everyone,
I'm having some latency issues on my EC500 freshly flashed with remora-rt1052-3.1.3.bin
Thanks to ColdTurkey's tutorial, I got it working (skipping the optional step #2 "Upgrade Kernel to 6.3RT" and #3 "FOR REALTEK NIC ETHERNET LATENCY ISSUES"), the led turns on when I get LCNC out of Estop.
Though, when I start linuxcnc, I get an error: "Unexpected realtime delay on task 0 with period 1000000" (config: remora-rt1052-basic).
Obviously, I though that skipping step #3 was a stupid mistake, so I followed through:
- Running sudo ethtool -i indicates a mismatched between the driver (r8169) and the firmware-version (rtl8168g-2_0.0.1 02/06./13)
- The next step was to run sudo geany /etc/sources.list but the file was empty so I ran sudo geany /etc/apt/sources.list instead and commented out the first line (deb cdrom:[Debian GNU/Linux 12_Bookworm...)
- I got to the next step and figured I'd run sudo apt-get install r8168-dkms like the example because there wasn't a packaged named rtl8168g.
- Then, I ran sudo ethtool -i again and found out that the driver did in fact changed to r8168 but the firmware-version line was now unexpectedly empty.
To make sure everything was fine, I ran "sudo dmesg | grep r8168" and got this:
Code:
[ 1.033714] r8168: loading out-of-tree module taints kernel.
[ 1.034002] r8168: module verification failed: signature and/or required key missing - tainting kernel

[ 6.743754] r8168: enp2s0: link up
Still, following these steps didn't fix the latency error message.
Rebooting doesn't seem to help, as a newbie, I'm clueless haha !
Also, I should mention that running apt get update gives many errors:
