STM32-E407 OpenOCD with ARM-USB-OCD

[kb1gtt]

I'm trying to program a Olimex STM32-E407 with a ARM-USB-OCD. The power LED is bright and the ribbon cable is connected. The console notes "Polling target stm32f4x.cpu failed, trying to reexamine" and I do not get the desired debugger. I launch via pull down "OpenOCD no interface" then I choose the below config file. Are there any suggestions on how I can get this programming cable to allow debugging?

Code: Select all

source [find interface/ftdi/olimex-arm-usb-ocd.cfg]

transport select jtag

# increase working area to 64KB
#set WORKAREASIZE 0x10000

source [find target/stm32f4x.cfg]

reset_config srst_only

Below is a copy of the console.

To create some breadcrumb for either me or someone else to find. I'm posting these notes about how I got the Olimex ARM-USB-OCD to program and debug a Olimex STM32-E407 using ChibiStudio.

-- Get Debugger working
1) Install WinUSB driver with zadig-2.5 for BOTH interfaces, see Olimex manual for some additional information. Verify Device manager shows with out a warning. As well Plug the ribbon cable into the JTAG header, and plug in the USB cables to both the ARM-USB-OCD and the STM32-E407 board. Make sure the power jumper is selected and the red LED is bright.

2) Save the below contents to blah\ChibiStudio\tools\openocd\scripts\board\olimex_stm32-E407.cfg

Code: Select all

# This is an Olimex STM32-E407 board with a single STM32F407 chip.

source [find interface/ftdi/olimex-arm-usb-ocd.cfg]

transport select jtag

# increase working area to 64KB
set WORKAREASIZE 0x10000

source [find target/stm32f4x.cfg]

# Take note the schematic only shows the trst line on this board.
reset_config trst_only

3) From pull down as shown below, set the screens as noted in these pictures.

Key command which are text selectable are below

Code: Select all

-c "telnet_port 4444" -s "${env_var:CHIBISTUDIO}/tools/openocd/scripts" -f C:\ChibiStudio\tools\openocd\scripts\board\olimex_stm32-E407.cfg

4) Compile project you need .elf file, select this elf file then follow the screen captures noted below.

If all goes well, you'll get similar results.

Take note your make file will also want to be similar to the below with no optimization -O0 and -g3.

Code: Select all

USE_OPT = -O0 -g3 -ggdb -fomit-frame-pointer -falign-functions=16

That should be the major stuff, happy programming.
