Hello, I have a question concerning flashing to external memory at 0x90000000 (discovery board STM32F7508-DK).
Maybe I missed something very basic, but despite searching a lot, I could not find a solution yet.
After compiling, I can flash using the STM32 ST-Link Utility and the application works fine. But I didn’t manage to flash
using VisualGDB (and OpenOCD), to external memory at 0x90000000. Exists somewhere a tutorial, that I can
follow for this topic ? I would be pleased to provide more information, if necessary. With kind regardsHi,
Programming external memories with OpenOCD indeed requires building and using a special FLASH programming plugin. You can find more information in this tutorial.
Hello, thank you very much for the quick answer, and the link to the tutorial ! As I understood, as first (to have the menu point ‘additional memories’) I have to upgrade to VisualGDB Custom Edition (I started with Linux Edition) ? And then .. pity .. my base intention was, to be able to set brakepoints in the code that is executing in the QSPI memory. But as I understood from tutorial, this is not possible ? Regards
Hi,
In our quick experiments, the breakpoints didn’t work in QSPI. This could be specific to a particular chip we used and could work differently on your one. You can try manually using the hbreak command in gdb to set a hardware breakpoint at a specific function in QSPI. If it doesn’t work, please consider checking it with ST – it might be completely unsupported, or might require some extra setup (e.g. disabling cache).
