Remora - ethernet NVEM / EC300 / EC500 cnc board

I'm not sure what was up with my mach3 firmware. I got stepper control to work with LinuxCNC and remora firmware. I'm warming up to linuxCNC after that mach3 debacle. Anybody get this to work with Probe_basic? Any configs would be great. I'm still getting familiar with the Hal and config files.

Now I see what you mean about the IO pinout headache for these BGA processors. At least with the STM32 you can put your leads on the pin. Do you think this new NXP processors is an upgrade or downgrade?

Is there a way with the DAP/Stlink to dump my EC300.bin file?

Definitely a speed improvement at 600MHz clock speed. I've started to re-look at DMA stepgen with the hope of increasing the step rate. With the fast MCU there may be hope to fill the step buffer fast enough.

Untested, but looks similar to J-link commands. To read (dump) the following may work, but I have already a copy of the original firmware in the repo.

pyocd commander -t mimxrt1050_quadspi -c "savemem 0x60000000 0x400000 ec300.bin"

Might give it a try.

I've got my board programmed using the pyocd method and assuming you arent making changes to the source this is super easy! Board is responding to pings and I also just received a Novusun NVMPG pendant. How goes the pin mapping of the EC500? Ive seen similar projects eg,  github.com/q3k/chubby75/tree/master/5a-75b/pin-scan use a pinscan program that would emit via serial what pin a given chip is connected to, wonder if we could try something similar to get the exact pin mapping of the RT1052 to the outputs
