[GCC] openocd fails to detect stm32f103xb_if due to USB HID issue

[kasunch]

I am using a custom designed STM32F103CBT6 based probe (somewhat similar to BluePill board design) and flashed with stm32f103xb_if project firmware. While the probe works with pyOCD as expected, openocd fails to detect the probe. Note that I am using the following part in the openocd script.

source [find interface/cmsis-dap.cfg]
transport select swd

Further investigation reveals that openocd fails to detect the probe while scanning for USB HID devices. As shown below, syslog also shows that there is an error related to HID input interrupt endpoint.

After some tinkering, I disabled usb-bulk module for stm3232f102xb_if in projects.yaml and re-flashed. Then everything starts to work as expected including openocd. The syslog output is shown below.

Looks the usb-bulk module interferes with usb-hid module. Any idea about why this happens?

[elfmimi]

what version of openocd did you use? openocd-0.11.0 should support bulk mode hid. older versions don't .

[kasunch]

I am using openocd v0.10.0. So, that would be the reason for this issue. I will check with openocd v0.11.0 and update this issue.

[mathias-arm]

@kasunch: were you able to confirm v0.11.0 fixes the issue?

[kasunch]

@mathias-arm : Sorry for being late to reply. Just tested with openocd v0.11.0. Seems to be working fine now.
