The SIMtrace v1.0 hardware is powered by the Atmel SAM7S microcontroller and the closest match for this platform is the atmel_at91sam7s-ek.cfg board configuration file. First try $ sudo openocd -f interface/jtagkey.cfg -f board/atmel_at91sam7s-ek.cfg …Error: An adapter speed…

He is working with most of the Taiwan Openmoko Team at the newly founded 0xlab and he was trying OpenOCD on the OMAP3 beagleboard. Yesterday I decided to go to their lab to hack with Matt on the Cortex-A8 support in OpenOCD. After downloading the datasheets,…
