Problems with arm-usb-ocd and TWR-K60N512

[dariojimenez]

Hi,

I'm trying to program the flash of the TWR-K60N512 by the debugger arm-usb-ocd and openocd but I have the next error. Any solution for that??

C:\openocd-0.7.0\bin>openocd-0.7.0.exe -f openocd.cfg

Finally, I have solved it by myself. The problem was that the TWR-K60N512 have a jtag connector of 20 pins but actually use it like a 10 pin jtag connector. (See the pictures)

yes the "good one" is Problems with arm-usb-ocd and TWR-K60N512

This is the same thread like Problems with arm-usb-ocd and TWR-K60N512, just to keep this in order I will consider that thread as the "good one"
