Hi. The programming interface changed from ISP to PDI on XMega controllers. The JTAG MKII can program and debug the XMegas via PDI with a software update, but only the newer hardware revisions seem to have the required hardware support. I'm not very happy to discard my current hardware and spend 300? for another one. So my question is: What are the hardware differences between the o...

Hi I'm using a 80C51F302 Cygnal device and I have based the design on what I've read on the Cygnal site that C2 is the way to go for such a pin-limited device. Well in the forum on the site some have commented that the JTAG interface is vulnerable to noise and 4k7 pull-up/down are recommended. But using a low-power device and putting load resistors on the signals seems futile to me. If...

I have a straight out of the box Olimex Arm-7 board, plugged into a just purchased Segger J-link JTAG adaptor. On powering up, the host software can't detect the target, the LED on the JTAG modules is orange. I posted this on the Segger forum, and the advice was that the Olimex board was in reset. I then posted this back on the Olimex forum and have not received any responses in a week. ...

I'm using an ST ARM Cortex part for the first time. I've been using Luminary parts until now. I notice that on the Olimex demo board for the STM32F103RBT6, they have the JTAG TRST pin connected, but on the Luminary eval board for the LM3S811 the TRST pin is left open. Does anyone know why this is? Is it just that the TRST pin is sorta optional, and the Luminary folks weren't in a m...
