Hi all, hi scotta,
I reflashed my EC500 with the newest firmware to check if the NVMPG now works.
After reflashing LinuxCNC doesn't connect anymore. The EC500 doesn't respond to pings either.
I wanted to erase the EC500 to reflash it from new, but erase doesn't work anymore.
Issuing this command:
pyocd erase --target mimxrt1050_quadspi --mass
returns this error message:
0000718 C No ACK received [__main__]
I use a DAP Link btw.

I flashed the newest firmware to a second EC500, and now this one seems to bricked also.
I can't erase nor re-flash both of them anymore.
How can I un-brick them?

regards, hanskuster
 

I'd resort back to MCUXpresso. When I've had trouble with bad firmware / flashing I've been able to recover the board by powering on while the probe is trying to connect. 

Thanks so much for the help!!!!

I cannot believe I am having this much of a problem... this will be the 3rd CNC system I have built... the first in linuxcnc but that shouldn't make this much of a difference...

I figure I have done something dumb or I have a defective piece of hardware.
 

Copy that, if it’s two years old … quite a lot has changed since then… glad you’re enjoying it.

Height is enabled,
dia is still out )

You guys are saints.
I often wonder if some people should use anything more complicated than a knife & fork.

Also completely disconnected enable wires as recommended

Upload here detailed pictures of the wiring and the hal and ini files.

Ok... saved and exited StepConf
Started config it saved
I hear the relay tripping on the BOB

Toggled E Stop and Power in UI

I see the DRO changing but still no movement on the stepper

Until section 4.2 the working directory is "linuxcnc-source-dir" and that is a nice change, but from then on it refers to the old naming "linuxcnc-dev" in the copy/paste parts.

If refers to using Geany that is not included with BookWorm, but it is with our version, so would not hurt to mention that if geany can not be found to install it with sudo apt install geany.

Same document a bit lower, add --show to latency histogram, it shows the excursions outside of the visible boundaries that are always, always ignored when checking latency as they are represented with very thin colored lines at the very edges of the graphs, so
latency-histogram --nobase --sbins 1000 --show

Finish StepConf, save, start the config and try to move the machine.
StepConf is a wizard, and very good at what it does, but it can not account for every hardware variant/version/setup out there.
Also, if you have drive enable wired, disconnect them till you get the machine moving, then you can wire and test enable.

One question, I'm studying the Remora-EC500-DMAstepgen, but I don't have any signal of pulses, could you tell me if in your tests, you were able to pulse the motors with DMA and this configuration? If so, could you tell me why this configuration is not happening? github.com/scottalford75/Remora-EC500-DMAstepgen

That repo is only for sharing of development work done on the STM32 for a DMA stepgen. The algorithm and DMA works but the STM32 was not fast enough to generate the step patterns. The only working DMA stepgen in for the RT1052 based boards.

I have 5v going to the BOB via a usb cable... both power and relay lights are on

am supplying 60vdc to the driver... green light on and I see power at the driver

driver has green light on

Just so we are on the same page... I am using Stepconf to test 1 driver and stepper motor...

changed base period , step time, and space as suggested

no change in behavior...

I have triple checked the wiring
