Toolchain setup for STM32-P407

[dimaie]

Hi,

I am trying to setup a toolchain to get a blinking led example running on STM32-P407 and ARM-USB-OCD but without any success. I am getting the following log from OCD when starting a debug session:

The last few statements are repeatable and I am wondering if anybody could point to the right direction.

So far I have done the following:

1. Downloaded the target board configuration and the processor id from 0x06411041 to 0x06413041 because the first one did not seem to be correct. After this I seem to get a valid initialisation sequence:

2. Cloned the project for the board STM32-P207 and modified it project.cfg to point to the target board configuration modified in the step 1.

3. Did steps 1 and 2 on Win 7 and Win XP machines just in case if it is a debugger driver issue.

4. Setup a telnet connection with the board and tried few commands manually it works fine until I load the executable file and run it. When the code is executed I am again getting

Warn : Invalid ACK 0 in JTAG-DP transaction
Polling target failed, GDB will be halted. Polling again in 300ms.

5. Setup the latest versions of Eclipse CDT, yagarto, OCD just in case if the debugger firmware is not compatible with Olimex setup and tried the project once again with the same results.

Does anybody have a working in Eclipse/OCD 'hello world' project for STM32-P407 and ARM-USB-OCD? Is there a way to make sure that the debugger is working correctly?

Thanks a lot.

Regards,
Dmitry

Without your cfg details I doubt anyone can help but in any case you might do better on the oocd ML.
They'll want the cfg(s) and -d3 from oocd.

I expect they'll want -d3 from oocd 0.7.0 or even current git (or whatever it is).

hmm, for a different board I had to remove the
cortex_m3 reset_config sysresetreq
might be worth trying.

I was able to download a program to the flash using the serial port.  The user guide has the following instructions, however, the Step 2 is incorrect.  They need to be open.

Step 0. It is good idea to revert all jumpers to default positions in the beginning
Step 1. Change jumper B0_1/B0_0 to B0_1 position (as said in the table print – "Boot Mode:System Memory")
Step 2. Close RST_E and BOOT0_E (below RS232 connectors)
Step 3. Close TX_BOOT_E and RX_BOOT_E by soldering. They are located on the back of the board near CAN connector.
Step 4. Download, install the Flash Loader Demo (from the STM32F407 web page, resources window)
Step 5. Connect RS232 and run the Flash Loader Application, the target is STM32F4_1024K (check the screenshots below).
