Maybe I can start mapping IO pins on the V5 EC500.

Yes, that's the RT1052 firmware extracted from the EC500 before flashing with Remora. Currently I don't have a "reliable" method to flash the original firmware back on the board. But I have done it with my DAPLink version, but others are not being successful with it unfortunately. pyOCD will be my next investigation I think.

It was not fun for the EC300, even with the MCU removed. I'm hoping it will as simple as setting up a whole GPIO bank as inputs / outputs and triggering them to see what they are connected to this time as we already have some of them (80%) working.Maybe I can start mapping IO pins on the V5 EC500.

Well pyOCD with CMSIS-DAP (ST-Link v2 clone with this firmware github.com/scottalford75/Remora-RT1052/b...SIS-DAP-STLINK21.hex) works way to easy!
Two commands and the board is flashed with pyOCD!!

pyOCD is definitely the way forward. I used pyOCD to flash the original Mach3 firmware and then with Remora to test.
The DAPLink drag-and-drop would not work when the original firmware was in place out of the box, but pyOCD had no issue to flash Remora onto the board.

I'm going to try pyOCD. I was able to flash my STM32 NVEM back to mach3 using ST-Link. Actually got the NVEM firmware from another user on here. I'm more familiar with SOC Linux then Arm processors.

Were you ablet to get any V5 board to work correctly in mach3? I hear tons of people having problem. I even have a few comments on the youtube video I posted.

Touch wood, I haven't had any issues with the 6 Novusun / Digital Dream boards now in the workshop.

I've never used Mach3, so can't say. One of the guys working on the EC500 with LinuxCNC just shared that his board has died, with what appears to be a voltage regulator issue.Were you ablet to get any V5 board to work correctly in mach3?

Hi scotta,
I just got St link today, following your video to create DAP link, Step 1 working, my computer shows 2nd ST link as removeable storge, But I have problem with Step 2. When I finished drag "stm32f103xb_mimxrt1050_qspi_if.bin" file to storge, nothing happens until I try to open one of 2 files on Maintenace, it reset itself then show fail log file.
Fail log file:
"error: The transfer timed out.
type: transient, user"
Any idea?
Thank you.!

Hello,
amazing reverse eng work!
Do you happen to know which Mach3 version you have backed up?
I started to play with this board and my laser but since i bought it from aliexpress i really feel like there will be no improvement (i'm having a bit of hard time using it with mach3).
How is the overall experience with linux cnc? never used it before
