I try Helios (for C/C++), using GDB hardware debugging with JLink. It has CDT already installed, and I installed GDB Hardware Debugging 7.0.0.201109151620 I try it with Segger J-Link, with gdb command arm-none-eabi-gdb from eclipse. I am building STM32Test from yagarto. I pasted scripts stm32_ram_jlink_[12].gdb into startup tab of Debug Configurations, but... When I start debugging, I get error dialog "Error in final launch sequence" with details of: Error message from debugger back end: Undefined command: "". Try "help". ,Failed to execute MI command: Yet the SEGGER J-Link GDB server log window shows success: Connected to 127.0.0.1 Reading all registers Read 4 bytes @ address 0x00000000 (Data = 0x20005000) Target endianess set to "little endian" JTAG speed set to 5 kHz Resetting target Sleep 100ms Select auto JTAG speed (2000 kHz) Writing 0x20000000 @ address 0xE000ED08 Read 4 bytes @ address 0x00000000 (Data = 0x20005000) Connection closed! So the J-Link GDB server is executing commands properly, but eclipse is not seeing that success.
what happens if you start the gdb manually and have it connect to the dgb-server (target remote command)? If that works you can check the helios - gdb connection Zox
In the manual of the J-Link is a description how to use it with Eclipse. And it works :-)
Thanks for the reply. #### I try gdb from command line: $ arm-none-eabi-gdb.exe -se test_ram.elf GNU gdb (GDB) 7.2 Copyright (C) 2010 Free Software Foundation, Inc.

(the yagarto STM32Test.zip may not be perfect for my STM32F103RBT6) I think my problem is with helios to gdb interface.
I was using indigo. My mistake. Works fine with Helios 3.6.2 Yet looking further now, it seems the ODeV/stf12 effort might be better.
