STM32 jtag chaining possible

Bernd Trauzold

Hi,

do you know if it is possible to use JTAG chaining with the STM32F103xC processors? Are there any specific things a controller have to implement to support jtag chaining?

best regards

    Hi,

    I've tried the jtag daisy chain feature with some LPC1758 devices, and unfortunately it's not working!!!!!!!!!

    I can see only one device by keil uvision (lastest version) in the Cortex-M target driver setup. I'm using the ulink2 interface.

    I've tried to download a programm to the devices and both of them downloaded this programm and the programm is running. But (of course) I'm not able to debug one of these devices...

    Did I forget something important???? Any advice is really appreaciated.

    best regards
    Harald
