uVision 5.24.2.86 drops out when trying to debug.

It seems to go through the motions, downloading etc and when it is due to reconfigure itself, it disappears.

This is a new installation on a new laptop (previous computer worked ok).

Tried un-installing and re-installing uVision and Si8051F_uVision.exe driver.

Suggestions?

  • Rene, thanks for your response.

    Debug driver SiC8051F_uVision.exe (v4.40 I think), downloaded it this morning to be sure it's latest. Removed previous versions first.

    The adaptor is the Silicon Labs USB Debug Adaptor. Hardware is our own design using C8051F361 processor.

    Target is powered from onboard PSU, 3V3. C2D is s shared IO line (P3.0) set as an output (with 1K pull up resistor). These have not changed from when it did work!!
