    I’m trying to see if I can debug a STM Nucelo-H7A3 with an Olimex ARM-USB-OCD-H debugger.  I’m have the debugger connected to the Nucelo with the Olimex ARM-JTAG-SWD and ARM-JTAG-20-10 as shown in the “Using Olimex ARM-JTAG-SWD …” tutorial.  And I’ve set up a simple project for the Nucleo board as described in that tutorial.   I get the error  below when I try to download and debug and the same error when I test the connection during project setup.  I’ve been trying to get some help from Olimex but it looks like they don’t have anymore suggestions to offer.  I’m hoping there’s an easy answer before I have to invest in the significantly more expensive Segger debugger.

    Thanks

    Sorry, this is not something VisualGDB directly controls. All we can suggest is to try contacting the board manufacturer or the debug probe manufacturer.
