Remora - ethernet NVEM / EC300 / EC500 cnc board

Great to hear! On the RT1052 boards the software encoder module is the only one available at the moment. Hardware encoder counting is on the to do list.

Hey guys what do you think I can do to recover this EC500 board? I’ve got no ack if I use daplink or esp board with wifi dap no matter what I do this happened after I flashed and debugged it than after that it was working and I restarted it and now no activity in the Ethernet or dap, solid two red lights. How can I recover this?

A couple of things to try

1. Turn the power onto the board whilst trying to connect
2. Jumper the BOOT pin and 3.3v and then turn on the board, try to connect.

On the EC300 there is a boot button which on occasion I've had to use to change the boot mode to allow a connection. Haven't had the issue with the EC500 though.

now i get the following using pyocd and my esp wifi dap link.
there is also a PRO_B pin too.

sudo pyocd flash remora-rt1052-EC500-beta.bin --target mimxrt1050_quadspi

I was able to get openocd to connect and i get this now.
