Hi,
I am running into some issues to connect with a target using an ST-LINK V3SET.
The setup is :
- Target: STM32F723IEK6
- Interface: SWD (dapdirect_swd / hla_swd)
- OS: 5.13.0-35-generic #40~20.04.1-Ubuntu
- OpenOcd: Open On-Chip Debugger 0.12.0-rc2+dev-00989-g9501b263e
(2022-12-06-23:45)
- libusb: libusb-1.0-0-dev/focal,now 2:1.0.23-2build1 amd64
The issue seems to be related to USB problems.
The error is stlink_usb_error_check(): STLINK_JTAG_GET_IDCODE_ERROR when
running :
`openocd -d -f /usr/local/share/openocd/scripts/interface/stlink-dap.cfg -f
/usr/local/share/openocd/scripts/target/stm32f7x.cfg`
Output is:
