Hello,

I'm using Reva Evaluation Board v2.10 with STR912F. After a long "try and find out" period i want to use the embedded rlink debugger on my own pcb for some tests with an ARM STR912FAW44X6.

On Rlink JTAG Interface there are 2 more pins in view of standard JTAG...these are DBGRQ and DBGACK. Do i need this pins for debugging on my own pcb? (in my opinion the two pins are not connected anywhere on STR912F Daughterboard)

I have installed the actual version of ride (BN 747).

My PCB works fine, but i don't understand why sometimes i can flash and debug without problems, and sometimes i want to flash in ram mode for debugging i've got error messages like "timeout" or "error expected from device".

[EDIT]
Sometimes i start debug i get the message that flash is protected and only a full chip erase can solve the problem, but i never had set any security bits in rlink options...

Maybe i have to break away rlink from reva MB?

best regards
Torsten
