openocd with picoprobe segfaulting on windows #3

benevpi · 2021-01-27T11:49:38Z

I followed the instructions in the Getting Started with Pico guide, and built OpenOCD for windows, but when I try to start it, it segfaults. I'm not even sure where to start with this. Is the info and warn details what are expected?

I'll investigate this today

liamfraser · 2021-01-27T15:40:28Z

This works with mingw-w64-x86_64-libusb-1.0.23-1-any.pkg.tar.xz. The latest libusb (mingw64/mingw-w64-x86_64-libusb 1.0.24-2) segfaults.

liamfraser · 2021-01-27T16:02:52Z

I have built it here. Can you try it out?

Yes. That looks like it's working

johnholman · 2021-01-28T18:30:11Z

Just hit the same segfault problem with openocd so tried the build offered by @liamfraser.
I got the same messages as above, but when I pulled out the USB connection to the pico Windows gave an error message about trying to reference memory at 0.

MimitechIndustries · 2021-02-03T20:07:46Z

I encountered this as well with the one I built just now, so instead I am using the binary provided here for now. Here is some basic stuff I got out of GDB:

I built both libusb v1.0.24 and the latest master manually and used the resulting DLLs -- v1.0.24 has the Segmentation Fault, latest master does not. Here's a better backtrace for the thread that is segfault'ing:

Following the Getting Started guide and getting same segmentation fault issue. (binary provided above seems to be working)

maxgerhardt · 2021-07-15T23:48:09Z

Just hit this problem too after compiling it myself using the official .

When I run it with GDB I see

Mind that my libusb-1.0.dll comes from the pyusb instructions telling me to use https://github.com/libusb/libusb/releases, that is currently version info 1.0.24.11584.

Using the release provided above, it works nicely. It also works if I self-compile the latest branch and just put in the libusb-1.0.dll that has version info 1.0.23.11397.

I think this is very crucial for Windows users and the instructions at https://datasheets.raspberrypi.org/pico/getting-started-with-pico.pdf should be updated.

maxgerhardt · 2021-07-17T02:42:23Z

In the linked libusb issue above I was also able to find out that when I use Zadig to load WinUSB drivers as opposed to libusb-win32 what the Raspberry Pi foundation's PDF is saying, using the latest released libusb-1.0.dll version 1.0.24 does not cause a crash.

It is also explicitly said in libusb/libusb#954 (comment) to not use use libusb-win32 but prefer WinUSB.

Can someone reproduce this non-crashing on WinUSB with latest libusb-1.0.dll besides me?

mcuee · 2021-07-19T10:14:15Z

https://github.com/libusb/libusb/wiki/Windows#Driver_Installation
Recommended: Use the most recent version of Zadig, an Automated Driver Installer GUI application for WinUSB (recommended), libusb-win32 (not working well, not recommended) and libusbK (only if you hit WinUSB limitations)

mcuee · 2022-05-20T11:52:03Z

The following libusb issue has been resolved in libusb release 1.0.25. Latest libusb version is 1.0.26.

Raspberry Pi foundation's version of OpenOCD segfault under Windows libusb/libusb#954

But WinUSB driver is still recommended and not libusb0.sys.

SubaruArai · 2022-07-13T04:22:42Z

Alright, I decided to bite the bullet and tried to cross-compile from Linux(Ubuntu 22.04 LTS) to Windows, and finally succeeded.

Also, I do highly recommend building in a container.

While waiting for the official fix and documentation update, I think this will do the trick.

mcuee · 2022-07-13T05:56:41Z

It is actually pretty easy to build openocd under Windows natively using MSYS2 ming32/mingw64. They have the formula for latest version of libusb-1.0, libusb-compat-0.1, libftdi1 and hidapi. They also have capstone. So you do not need to build them by yourselves.

On the other hand, I understand why people like to use Cross Build -- the speed might be a bit faster once you have the build scripts ready. And if you are more familiar with Linux than Windows, why not?

SubaruArai · 2022-07-14T01:15:37Z

@mcuee My bad, didn't notice that.
I recently tried to build under msys2 but failed, which led to me doing cross-compile.

I also find it being much more stable - everything is statically linked, and every library version (except mingw) is defined (no more build failure due to system updates!).
Btw, being in a container is a HUGE benefit, IMHO.

But then again, this is going off-topic, so I'd end my bragging.

mcuee · 2022-07-14T02:58:36Z

All in all, I think this issue can be closed as the upstream libusb issue has been resolved. You should really use libusb-1.0.26 for new build of OpenOCD.

For people who are still using libusb-1.0.24, you can have a easy work-around as well -- just use Zadig to install WinUSB driver.
