Hi, I’m trying to build OpenOCD (under Cygwin under Win7)… but I can’t get beyond: $ ./configure --enable-ftdi … configure: error: libusb-1.x is required for the MPSSE mode of FTDI based devices Any suggerstions? Thanks, Tom

@jvanier , does it support the particle ftdi?

@jvanier and @bko , I understand that the FTDI FT2232H on the programmer shield functions as a USB-to-JTAG converter, and that JTAG is how the programmer talks to the Photon (target). But I was looking for a pointer to a spec of some sort that details the instructions/commands that are sent via the…

@jvanier , I received my programmer shield… I plugged it in and it seems to have installed properly. I tried the windows binary you suggested (freddiechopin), using the CFG file (particle-ftdi.cfg) from the programmer-shield repository. [startup] 516 /cygdrive/c/trash/openocd-0.9.0/bin> openocd -…

@k2tom , you seem to have confirmed my concern that the pre-built image is NOT compatible with the particle-ftdi device. Which basically means we have to compile openOCD with the particle cfg file present. However, compiling on Win7 is the problem I am having.

[image] k2tom: I tried the windows binary you suggested (freddiechopin) I found this note on Freddie Chopin's website : One important information from my side - currently all interfaces using libftdi library require WinUSB driver (previously libusb-win32 was required) - this change is relate…

It did not seem to help me. But just to “calibrate” things… here’s where I stand now. I’m NOT able to build OpenOCD because of the missing libusb-1.x. I used Zadig to install the WinUSB driver for when the Photon is connected directly (i.e., NO programmer shield) to my PC and in “Photon DFU Mode”…

I finally got around to trying the Programmer Shield on Windows 10, and fortunately I didn’t run into any issues*. I was able to make it work by installing all the software and the drivers. I documented all my steps. Debugging Particle on Windows I relied on the the toolchain installer by @mumblep…

@jvanier , so you used the pre-compiled versin of openocd, used zadig and played with which drivers for the Particle FT2232?

Have you tried using a binary from here : http://www.freddiechopin.info/en/download/category/4-openocd
