我在工作中习惯使用 Segger，但我不想花那种钱在家使用，所以这是我第一次使用 OpenOCD 进行调试。我有 Olimex ARM-USB-TINY-H。

我的操作系统是 Ubuntu。我正在使用带有 OpenOCD 插件的 MCUXpresso (Eclipse)。我在 gdb 连接到 OpenOCD 时遇到问题。任何指针都会非常有帮助。

我已将配置选项设置为

-s /usr/local/share/openocd/scripts/  -f /usr/local/share/openocd/scripts/interface/ftdi/olimex-arm-usb-tiny-h.cfg -f /home/username/Documents/Code/kl27z-ARM_USB_TINY.cfg

控制台输出：

Open On-Chip Debugger 0.10.0

For bug reports, read
    http://openocd.org/doc/doxygen/bugs.html

adapter speed: 1000 kHz
none separate
cortex_m reset_config sysresetreq
Started by GNU MCU Eclipse
Info : clock speed 1000 kHz
in procedure 'init' 
in procedure 'ocd_bouncer'

Eclipse 弹出这个错误：

Error in final launch sequence
Failed to execute MI command:
-target-select remote localhost:3333
Error message from debugger back end:

这是 .cfg 文件

# inteface: olimex arm usb tiny h
# transport: swd

# adapter/interface
#interface ftdi
#source [find interface/ftdi/olimex-arm-usb-tiny-h.cfg]

transport select swd

# increase working area to 16KB
# set WORKAREASIZE 0x4000

set CHIPNAME kl27

#reset_config srst_only srst_nogate connect_assert_srst
reset_config none separate

source [find target/klx.cfg]

ftdi_layout_signal SWD_EN -data 0

$CHIPNAME.cpu configure -event examine-end {
    kinetis mdm check_security
}

#gdb_memory_map disable

$_TARGETNAME configure -event gdb-attach {
   echo "Halting Target"
   reset init
}

更新，运行 --debug 0 控制台的最后一部分是

我想通了，它主要是 ftdi 驱动程序，但也有一点配置。我概述了我在博客上所做的事情。 https://mitchjonesengineering.us/?p=18
