Hello, great job with porting remora to these boards.
I went through a lot of post on this forum thread, but I'm not able to find the schematics for the EC500. Does anyone have a reverse engineering version of the PCB schematics? Thanks!

I need help about downloading config.txt to nvem v5.
I succeeded in downloading renoma nvem-rt1050 throw MCUXpresso IDE. 
and received ping from nvem like below. 
Code:
[code]cnc@raspberrypi:~/linuxcnc/configs/remora-nvem-basic$ ping 10.10.10.10 PING 10.10.10.10 (10.10.10.10) 56(84) bytes of data. 64 bytes from 10.10.10.10: icmp_seq=1 ttl=255 time=0.443 ms 64 bytes from 10.10.10.10: icmp_seq=2 ttl=255 time=0.143 ms 64 bytes from 10.10.10.10: icmp_seq=3 ttl=255 time=0.141 ms ^C --- 10.10.10.10 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2029ms rtt min/avg/max/mdev = 0.141/0.242/0.443/0.141 ms

However, if I try to send config.txt, a timeout occurs.
Code:

As I see the letters in the temianl as below, I think the firmware was well put, but I don't know why it's not working.

Hello!
I'll try to flash remora firmware for my new board, but how do you know which pins are the SWCLK, SWDIO? I suppose the bottom one is the GND.

Hey guys!
Successfully installed firmware, now it's moving :)
Do you have a full config .file, for spindle, inputs, outputs etc. for sample?
Tried to add homing switches, I wrote remora.input.03 but it said unkown pin.
I have dual Y axis, I followed the tutorials but only one motor is moving, if I set sync home sequence it will be OK?

Great to hear. There are example configs in the following link. Check out the hypercube hal and ini files. This shows how to setup dual axes. Dual Z in this case but the same is for dual Y. For a dual axis setup, don't jog in manual until after you have homed the axes, they will not jog together until homed.

Now it's working and stable!
Thank you for your work, it's awesome that we can use this cheap controller, we had a lot of problems with Mach3.

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 [    1.048699] r8168 Gigabit Ethernet driver 8.051.02-NAPI loaded [    1.064274] r8168: This product is covered by one or more of the following patents: US6,570,884, US6,115,776, and US6,327,625. [    1.066307] r8168  Copyright (C) 2022 Realtek NIC software team <nicfae@realtek.com> [    1.094005] r8168 0000:02:00.0 enp2s0: renamed from eth0 [    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:
Code:
