I need to use the JTAG probe on a board with a Blackfin BF704 DSP.
However, the BF704 is locked (security enabled in the OTP of the Blackfin).
So, I need to specify the JTAG key so that I can debug this processor.
However, if know how to do it for a BF706 (it needs only to edit the ADSP-BF706-resets.xml file, located in System/ArchDef directory of CCES installation), there seems not to be such a file for the BF704 (no ADSP-BF704-resets.xml file in this directory).
So how can I specify the JTAG key (the four registers "userkey0", "userkey1", ...).
Thanks in advance for any help,
