    Stable Release v1.9.2 Stable

    esden released this 2023-09-16 23:42:45 +02:00 | 3494 commits to main since this release

    We are happy to announce the v1.9.2 point release of Black Magic Debug.

    In this release

    • Fixed building BMDA due to alloca not being defined. [hydra]
    • Fixed an issue with the fake threads implementation that can hang certain IDEs [dragonmux]
    • Soft TPWR ON: Mitigates target power enable brownout issue on v2.3 hardware [dragonmux] [esden]

    Note: The brownout mitigation was also implemented for all older native hardware versions. Read below for more information.

    We had reports from some users that the V2.3 hardware was resetting/crashing when the user enabled target power using the monitor tpwr enable command. During the investigation it turned out that the BMP was browning out. The GD32 found on the V2.3 hardware has higher minumum voltage requirement than the STM32. This means it will brown out more likely if the 3.3v rail dips. The solution to this problem was to slowly turn on the target power using PWM instead of instantly turning it on.

    We also tested the solution on older hardware versions that use the STM32. Those were also experiencing a significant voltage drop. Additionally after the voltage drops the rail voltage overshoots by a significant amount. Because the overshoot we decided that it is a significant issue, as it can have adverse effects on the connected user targets. We decided to backport this fix to older firmware releases (1.8 & 1.9) as well as older hardware (all native hardware versions except for hardware version 0 as it does not have TPWR control).

    To illustrate the problem and solution here are some oscilloscope traces:
