Thanks, good to know I was barking up the wrong tree. For years I have been debugging using JTAG probes. Usually on Kinetis parts using their own hacked up version of eclipse. I am new to the openDCD and raw GDB debugging. But all the documentation makes it look easy once i get the JTAG thing up and going. Tomorrow I will have an new tree to bark at. Thanks for your help Dave

HI Jason, I have flashed both of my devices to: Black Magic Probe (SAMD2), (Firmware v1.6.2-5-gca7bf01) I still see 2 serial ports at 6018 none at 6017. When I hold the switch down to put it in bootloader mode, I see a single device at 6017, but that is useless for debugging. Is this the correct firmware now? Am I misunderstanding how this thing is supposed to work? Thanks Dave

I just got my second one in. As expected it has the same problem. One difference was when I first plugged it in to the Windows 10 machine it did a little dance and acted like it might have updated the firmware but no, It has the same problem. It's been a while since i did an substantial Linux stuff. the only operating Linux machine I have is a raspberry pi. I tried but for me that is a giant pain. How about I mail you both of the devices and you can update them for me? Hopefully Dave

Everything works better in the morning. Ill try again then. You have been awesome!

Ok i have it up in DFU Demo mode. It does show a PID of 1d50:6017, But alas :: Invalid DFU suffix signature A valid DFU suffix will be required in a future dfu-util release!!! Cannot open DFU device 1d50:6017 No DFU capable USB device available

i dont understand (just to be clear).. Unplug the device, Push the button, Plug it in while holding the button. continue holding the button while executing the command?

I just ordered another one from amazon. Delivery tomorrow.

No DFU capable USB device available I don't think it likes me anymore. I get the same response if I try the 6018 PID. If I've popped it I dont mind buying another one. Thanks for getting back to me!!

I realized I never formally downloaded the Blackmagic-master. so I just ran the script and this happened: PS C:\Esp\frameworks\esp-idf-v4.4.1> dfu-util -d 1d50:6018,1d50:6017 -s0x02000:leave -D C:\Users\dave\Downloads\blackmagic-master\blackmagic-master\src\blackmagic.bin dfu-util 0.9 Copyright 2005-2009 Weston Schmidt, Harald Welte and OpenMoko Inc.

Hi Jason, I got one of these jeff probe blackmagic JTAG clone from Amazon. I intend to use it on the ESP32-s2 chip using eclipse. I am running windows 11. When i look at it in the device manager it looks like two com ports. They both have the same PID 6018. I think when it is working correctly it should show 6017 (for the JTAG side) and 6018 for the UART side. The second port does not seem to work as a UART and of course the JTAG is a non starter. So I suspect I need to flash it with some new firmware. I tried the sketchy and scary Zadig jive it times out on both the Win11 and Win10. I have So after too much (but likely not enough info).. How do I flash the part? or should I just pack it in and go another route?
