Remora - ethernet NVEM / EC300 / EC500 cnc board

Hmm. I'm guessing this is with the DMA stepgen. I thought my last changes had solved that issue. It's not a LinuxCNC config issue.

If you could monitor the situations which lead up to this bug that would be appreciated so I can try to narrow down the underlying cause.
 

Hi scotta,
yes, I use the version remora-rt1052-3.1.0.bin
not only restarting the software changes the direction at random. Toggle machine power changes the direction also.

Regards, Hans

I was able to confirm the direction output issues. My approach to getting the step and direction outputs into a "known" state during restarts was not consistent. So, with this bugfix I'm reading the actual output port DR register and then performing a direction change if needed. Happy testing and thanks again for the feedback. We'll get this stable.

I'll merge the bugfix branch once we have some feedback.

I'm having a similar problem to user oficinerobotica when trying to flash a ec500 with a pi pico using a windows machine. The board date is 2022-09-07.

When I try to use
pyocd flash remora-rt1052-EC500-beta.bin --target mimxrt1050_quadspi -v
I get the error
0001433 I Target type is mimxrt1050_quadspi [board]
0001534 C No ACK received [__main__]

I'm not using resistors and don't have 3.3v connected to boot.
I have gnd, 24v, com- and com+ connected to power.
Anyone have any ideas as to what might be the problem?

lol user error. I had the black wires in the diagram mixed up. it looks to have worked but not sure.

After a bit of fidling I completely given up on the pico route and just ordered 2 cheap ST-LINK's . With the particular ones that I got , it turns out they work out of the box for flashing the EC500. I didn't even needed to flash the custom firmware on the stlink. If you get the ST-LINK try first a flash just the way they are before flashing one of them as per scotta instructions.  Unfortunatly I don't have the time and knowledge to dig deeper and make the pico work

Edit: I see you got it working lol. I just missed your second post. Sorry for the noise

As far as I can tell it worked. I'm not sure if there's some way to ping the board or something using windows to verify. The led configuration definitely changed. I now have 4 LED's on that were not before.
