hi,
i have been struggling with Olimex board cs-e9302 and its JTAG device arm-jtag-tiny (using openocd). i can’t get it to work.i have used this same JTAG before with Olimex board SAM7-p256 so i think the JTAG itself is ok. howeve when i try it with the cs-e9302 i can’t get it to work, i can’t halt the processor, i can’t reset. every thing returns and error. here is the outputs:

i have tried all jtag_speed starting from 0 to 20
all reset_config trst_and_srst , reset_config trst_alone
any body have any ideas. i’m desperate here.
Thanks for help
