--- ** [tickets:#363] OpenOCD dose not work debugging with mbed.** **Status:** new **Milestone:** 0.11.0 **Created:** Tue Sep 06, 2022 08:14 AM UTC by JIN LEE **Last Updated:** Tue Sep 06, 2022 08:14 AM UTC **Owner:** nobody **Attachments:** - [ocderror.jpg](https://sourceforge.net/p/openocd/tickets/363/attachment/ocderror.jpg) (58.6 kB; image/jpeg) i'm using mbed 6.15+STM32H743VI. i start the debugging, it works no problem until my board power off. but the problem arises, when the power on again after power off. if erasing a flash memory(using st-utilty), it become possible debugging agian. i think, it is not hardware or wiring issue. because, i tested my board with mbed 5.15 and cubeIDE(without OS). this problem only happend with mbed6.15. Is it not compatible with mbed6.15? this is my error log. ======================================================================== C:\Users\jsshin\AppData\Local\VisualGDB\EmbeddedDebugPackages\com.sysprogs.arm.openocd\bin\openocd.exe -c "gdb_port 60213" -c "telnet_port 60211" -f interface/stlink-v2.cfg -f target/stm32h7x_dual_bank.cfg -c init -c "reset init" -c "echo VisualGDB_OpenOCD_Ready" Open On-Chip Debugger 0.11.0 (2021-11-18) [https://github.com/sysprogs/openocd] Licensed under GNU GPL v2 libusb1 09e75e98b4d9ea7909e8837b7a3f00dda4589dc3 For bug reports, read http://openocd.org/doc/doxygen/bugs.html WARNING: interface/stlink-v2.cfg is deprecated, please switch to interface/stlink.cfg Info : auto-selecting first available session transport "hla_swd".
