To begin with: TX from Remora on NVME v5 to MPG is working fine, display is updated accordingly to LinuxCNC status. Only RX part, transmission from MPG to NVME is not there.

 

When you say the "transmission from MPG to NVME is not there", what are you expecting? The serial communication for the MPG is used to update the display and receive button presses. The A and B pairs are directly wired to the handwheel encoder.

 

On TX pin I was expecting constant transmission of display updates - and I definitely see that with the scope.

On RX pin I can also see UART-like transmission with RS232 levels when there is a key press with RX line floating, but when I plug it to NVME it seems to be short-circuited to ground.

I can see encoder pulses on both A and B pairs also when plugged in to NVME, but LinuxCNC is not responding to these nor was I able to detect any reaction to that in HAL.

About that pendant wheel - now I recollect that it is directly wired to AB pairs and *only* to these, so as expected there is no UART transmission going on when turning the pendant. Pulses, however, are there.

I tried running HAL watch on all `remora.input.*` pins and located pendant A and B on pins 25 and 26 - where in my config it was supposed to be on 20 and 21 (jogging is still not working though, but I guess that's because lack of RX to select which axis to move).
Similarly, INP3 on NVEM v5 is input.06 in HAL.

That made me thinking, maybe I've got something wrong in my software? To recap, what I did for Linux + NVMEv5 + NVMPG was:

1. Flashed github.com/scottalford75/Remora-RT1052-c...ora-rt1052-1.1.0.bin with CMSIS-DAP
2. Uploaded github.com/scottalford75/Remora-RT1052-c...xCNC/nvem-rt1052.txt config with `upload_config,py` utility
3. Installed Remora, Remora-eth and NVMPG components from github.com/scottalford75/Remora/tree/fea.../LinuxCNC/Components
4. LinuxCNC config I am using: github.com/scottalford75/Remora-RT1052-c...sic/remora-ec500.ini

Is that correct set?

Found it - turned out MAX3232 IC on my NVEMv5 was shot. Replaced it and I've got the MPG working.

Does anyone know if there are some additional RAM sticks on the EC500 or well chips not sticks haha, or how much ram is available on the board? I don’t have my board in me so I can’t check.

The onboard memory is W25Q32JV QSPI Flash [32M-BIT : 4MB].
 

How about RAM?

No additional RAM, so only the 512KB on-chip.

 

 Hi, i have some troubles with EC500 - remora-rt1052-1.1.0.bin.
1. Flashed - ok
2. Ping 10.10.10.10 - ok
3. import tftpy - okThe problem is when i execute "python3 upload_config.py ec500-rt1052.txt" - > config.txt is generated, but no transfer to EC500. Same is with TFTP.UDP port 69 is opened.
