stm32f4 with nucleo-f401RE
hi,
i’m working with the nucleo f401re (and other cards like nucleo l476rg or 32f476gdiscorvey).
for the nucleo f401 re, i cannot connect to the card with openocd.
I downloaded openocd to 0.9.0 and it worked fine in console mode.
(i can too attach the debugger to open ocd in eclipe)
i also pointed the executable in the plugin and i arrive start too in console mode (see below)
C:\Ac6\SystemWorkbench\plugins\fr.ac6.mcu.externaltools.openocd.win32_1.12.0.201611241417\tools\openocd\bin>openocd -f “C:\_work\_webminar5\OpenOCD-20160901\share\openocd\scripts\interface\stlink-v2-1.cfg” -f “C:\_work\_webminar5\OpenOCD-20160901\share\openocd\scripts\target\stm32F4x.cfg” -s “C:\_work\_webminar5\OpenOCD-20160901\share\openocd\scripts”
i think that something doesn’t work in the eclipse configuration for this board to start openocd because i can debug for the other board above and openocd work fine.
(see below the log)
