Qt Creator: Disassembler failed

[Cedric Jehasse]

Hi,

I've configured a Bare Metal device with OpenOCD in Qt Creator.
If I right-click in the stack view and select "Open Disassembler at 0x..." i get a message "Disassembler failed:" in the Debugger log.
The addresses shown are 64-bit with the first 32 bits set to 0xffffffff. But the target is a 32 bit mips.
If i choose "Open Dissassembler at Address", and enter a 32-bit address it works.

I think the error is because 64-bit addresses are passed to the disassemble command, but the addresses in the dump are 32-bit and Qt Creator can't match them.

Is there some configuration that needs to be done to avoid this?

thanks,
Cedric

Below is the Debugger log output:
