Hi guys, I've build my own SAM9260 board and now trying to get the hardware working. My problem at the moment is the JTAG interface. The PEEDI from Ronetix show me a BYPASS error, but ignores it and so it is possibe to access the registers and configure the 9260 via JTAG. My FT2232 based debugger with OpenOCD fails due to a JTAG error. I think this is because of the BYPASS error. ...

Hello friends, i recently get my AT91SAM7S-EK; for JTAG connection i got an ARM wiggler that goes from JTAG port to DB25. Since my lap has no DB25 port i have to connect the wiggler to a DB25 - DB9 - USB cable. (which means that i have a device that converts a DB25 to DB9 and that DB9 output is then connected to a DB9-to-USB cable) Now, i'm working with openOCD but i don't exactly now what i ha...

Hi all, I'm working on setting up a development environment using Kdevelop and FreeRTOS for the SAM7S64. It's taken a bit of work because the FreeRTOS port and demo app weren't finished and all of the ISRs had to be rewritten, among other things. I've also got it working (to some extent at least) with a remote J-Link JTAG pod. For troubleshoot
