  • Connection issue: "Could not power-up debug power domain"

    Hi,

    I have a similar issue as in "Thread 2538" but I didn't find the solution there.
    When trying to connect (in IAR IDE, "Debug without downloading") I get following output:

    I try to connect to an FPGA running my own customized ARM-Cortex-M0 (means I'm not using any specific STM32 platform or whatever).
    The M0 is configured to use SWD (no JTAG), there is only one power domain for the whole chip, so for sure the debug power domain is powered up. Debug is enabled on the M0 as well.

    The M0 is running before I try to connect, it is executing some code from internal ROM (there is no flash on the FPGA).

    Could you please point me into a direction to further investigate? At the moment I'm stuck with this Jlink warning...

    Thank you very much,
    Daniel
  • HI,

    Can you please start J-Link Commander (JLink.exe) which is part of the J-Link software package and upload a screenshot of the entire output?
