Hi,

VisualGDB Project Properties does not support editing the FLASH/SRAM addresses as they are usually defined by us in the BSPs. Looks like your project is a stand-alone project, so you can modify the FLASH/RAM parameters directly in the stm32.xml file:

    <FamilyID>STM32F4</FamilyID>
    <FLASHSize>1048576</FLASHSize>
    <RAMSize>196608</RAMSize>
    <FLASHBase>134217728</FLASHBase>
    <RAMBase>536870912</RAMBase>

Hi,

Thanks for the detailed log. It looks like the _estack value in your image does not match the one in our linker script and it ends up pointing outside the RAM area on your chip, causing runtime errors. Please fix the value of _estack so that it points at the actual end of RAM.

VisualGDB should normally show a warning that the end of stack is not writable; if this does not happen, please let us know and we will investigate and fix.

Hi,

It is included in the latest BSP update the is currently undergoing tests. We would expect it to be released in the next 1-2 weeks.

Sorry about that, it’s a known limitation of ST-Link. This happens because one ST-Link tries to execute a single instruction when stepping over the code, an interrupt arrives and your board starts handling it.

As a workaround, please consider setting the $primask register to 1 via the Watch window during stepping.

This will temporarily disable interrupts. Please do not forget to set it back to 0 once you are done stepping, as otherwise the interrupts won’t be re-enabled.

Hi,

Sorry, the log you attached was the build log, not debug log. Please follow the instructions described here to capture a debug log.

Hi,

Just wanted to let you know that instead of hardcoding the library paths, we would recommend adding “=/opt/vc/lib” to the “library search path” field.

Regarding the project conversion, the easiest way to do that is to add another configuration and copy the settings there. As switching large projects between direct and cross-build looks like a relatively rare scenario, we don’t want to add a specific fully-automatic command for it. That said, if we get more requests for this feature, we will reconsider this.

Hi,

Normally the reference to the imported hardware register file should be saved to the <mcu>.xml file in your project directory (see the EmbeddedProfileFile element in the .vgdbsettings file).

Please ensure that this file exists and is writable.

Hi,

OpenOCD is the recommended debug method for embedded targets, so it should normally work.

Please try enabling GDB logging via VisualGDB Project Properties -> Advanced GDB Settings and post the full gdb log along with the OpenOCD output here. It should explain what is going on and why the target is not resumed.

Hi,

VisualGDB takes the RAM/FLASH size values from the bsp.xml file in the BSP directory. It is hard to say why they could be wrong without knowing the MCU type.

Please let us know which MCU you are using and what are expected/observed values and we will investigate this.

[support]

Hi,

We will try to address it in v5.3. We expect the first preview build of v5.3 to be released in the next month, although we cannot guarantee that this fix will be included early in the release cycle.

[support]

Hi,

Yes, it will be included in v5.2R9.

In the meanwhile you can download the latest daily build here: http://sysprogs.com/files/tmp/VisualGDB-5.2.15.1423.msi

Hi,

VisualGDB Python support is mostly targeting the cases when you want to debug Python <=> C/C++ integration issues. If you are debugging Python-only code, other products (not dependent on GDB) would simply provide faster and smoother experience. You can still use VisualGDB for python-only debugging, but this is not our primary use case and VisualGDB is not optimized to handle it in the best possible way (that would require a completely different debugging technology not related to VisualGDB).

Hence if you are looking for Python-only debugging, we would advise checking Python-specific products and IDEs.

Hi,

The UsbDriverTool is actually included in our OpenOCD package and can be launched using the “Start driver tool” link shown if you switch OpenOCD to custom mode.

Regarding the documentation, we usually try to organize it in the format of tutorials, but if you believe a user-edited wiki could be more helpful, we could certainly host it.

[support]

Please try enabling the verbose mode for the linker (add -Wl,-verbose to the LDFLAGS) to see a detailed log on the paths checked by the linker when it attempts to locate those files. This should explain why they are not found.

[support]

Hi,

Our STM32 package was last time updated in December 2016, so it does not include the latest package from Feb 17. We are currently building the new STM32 BSP and expect to release it in the next 2-3 weeks, so if you don’t want to go through resolving the import issues yourself, we would recommend simply waiting until we fully support it.
