  • [SOLVED] J-Link Base troubles to connect to CYW43907

    Hi,

    I'm working on a USI module (WM-AN-BM-23) which embeds the CYW43907.
    I have troubles to connect to it. I've attached two pictures where I'm monitoring SWDCLK pin and reset pin.
    The good behavior is when the reset pulse is occuring right after there is activity on SWDCLK pin.
    The bad behavior is when the reset pulse occurs after few seconds, after the JLink commander gives up in connecting to the target.

    The issue that to have the good behavior is that I have to do the reset down manually. Normally (as it is shown in the bad behavior), the reset pin is connected to pin 15 of the Jlink.

    Are you aware of such a behavior with this kind of target?

    Thanks.
