Hi,

Just wanted to let you know that we have updated VisualGDB to run the Cygwin build of CMake using an alternate mechanism that does not trigger the problem. Please use this build: http://sysprogs.com/files/tmp/VisualGDB-5.4.7.2524.msi

It also looks like as of v3.12, the Cygwin-based build of CMake would crash when trying to reload a project without restarting it:

assertion "0" failed: file "<...>/CMake/Utilities/cmlibuv/src/unix/core.c", line 185, function: uv_close
    0 [main] cmake 33156 cygwin_exception::open_stackdumpfile: Dumping stack trace to cmake.exe.stackdump

If you ever encounter that message, please right-click on the project in Solution Explorer and select “Reload CMake Project”. This will restart CMake and reload the project successfully.

Hi,

This might be caused by this bug. Please try patching your esptool script as shown in the bug thread.

Hi,

Looks like you forgot the “\n” symbol at the end of the printed line. With the default settings, this will cause the C library to buffer the output internally until either a newline is sent, or fflush() is called explicitly.

As a workaround, please simply add “\n” at the end of the line you print.

Hi,

No problem and thanks for reporting this. We have fixed it in the following build: http://sysprogs.com/files/tmp/VisualGDB-5.4.7.2519.msi.

Hi,

Thanks very much for sharing this!

Hi,

No problem. Let us know if you encounter any issues and we will try to help.

Normally the importing process described in the tutorial should work, however it looks like it does trigger a gcc bug on particularly large projects.

Hi,

Yes, please try using variables like $(ProjectDir). You can see the full list of variables by clicking the link at the bottom of the project properties window.

Hi,

Just to ensure we are on the same page, could you please summarize the current state of the problem with NMake paths? I.e. what you are trying to achieve and what you are observing.

We have also rechecked variable expansion in both path mappings and gdb commands and could not reproduce any errors. Please let us know the exact steps to reproduce the behavior you are observing and we will help you get it to work.

Hi,

The post-build steps can run on any machine of your choice – they are fully customizable. If you are currently using VisualGDB trial, this feature should be already enabled. If you have already purchased a Linux edition key, please contact our sales to get a trial extension voucher so you could try out the Custom edition features.

Supporting “make uninstall” out-of-the-box would be tricky. As CMake scripts run on the Windows machine, it would involve running it locally, recording the exact steps it does trying to replay them on a remote machine (or simply removing all files previously installed by VisualGDB). We might be able to eventually support it, but given the complexity and the limited scope of this, it won’t be included in v5.4, sorry.

That said, we can help you setup the correct custom actions to do the uninstallation as a custom shortcut. Let us know if you run into any difficulties and we will help.

Hi,

Thanks for clarifying it. Unfortunately it would’t work to not count the space between the symbols, as in most of the cases such space is wasted due to alignment constraints, or contains unnamed data from assembly files, and hence should be counted towards the used space.

Instead, please consider one of the following approaches:

• Instead of having fixed-size sections extended until the end of the 62K block, have a variable-size section followed by a dummy section marked with the NOLOAD attribute filling the rest of the space. The NOLOAD sections will be automatically excluded from the memory usage statistics.
• Simply place sections non-sequentially. You can use the “. = <address>” syntax in the linker script to place the next section at a fixed address.
• Split the FLASH memory in your linker script into 3 separate memories and place the sections accordingly. Again, ensure that the sections are not extended beyond the actual end of the last symbol.

Hi,

Normally this should be sufficient. As a quick check, please try creating a new “LEDBlink” project, calling printf() from it and referencing the fast semihosting framework. If it does work, please recheck the differences between the test project and your original project.

Another option is to try setting a breakpoint in the WriteRawFastSemihostingData() function and stepping through it to see if s_FastSemihostingState gets modified properly.

Hi,

Sorry, the assembly file syntax used by IAR and GCC is completely different, so most of the assembly files would need to be heavily rewritten. It should not be related to using Make or MSBuild, just the syntax inside the assembly file.

That said, if the files come from the ST’s SDK, there should be equivalent versions of them for the GCC compiler. If you are not sure, please let us know what exact assembly files do not build (i.e. full path to the file and its contents, if possible) and we can advise on finding a GCC-compatible replacement.

Hi,

You should be able to add it via VisualGDB Project Properties -> Build Customization -> Post-Build Steps (requires the Custom edition).

Although CMake itself doesn’t support uninstalling targets (and it won’t work for the deployed files), you can add a custom shortcut (will appear under the Project menu when your project is active) via VisualGDB Project Properties that will run arbitrary commands of your choice (e.g. deleting a specific set of directories).

With the forum subscription, we had issues with it before due to email servers treating the notification emails as spam. We have re-enabled it for now, but we may have to turn it off again if the problem with the mail servers returns.

Hi,

Good to know it works. Sorry, our interface for viewing the tutorials doesn’t show the changes, as the old steps won’t be relevant for the users that started with the new version of the tutorial.

We have modified the publishing date to make it explicit that the tutorial was updated.

Hi,

If the project is msbuild-based, the static library project can be built without a .vgdbsettings file, hence you can simply keep the original files and not change anything.
