Greetings to all ST community. Hope some of u guys can help me a little.
It happened like that: i have broken my st25r3911b-disco board with a corrupt firmware.
And now when i`m trying to connect the disco board to the st-link v2 thru a 20-pin jtag and a cortex 9-pin adaptor i just get this error: 'unknown device id'. (st-link utility is switched to jtag mode).
What am I doing wrong? any ideas?
