Hi, Can I use the Rlink board attached to the REva motherboard on the dev. kit to debug an external prototype? I assume the 20 way header on the Rlink board (v2.02) is a JTAG port, presumably intended for this purpose- Is it just a question of altering the jumpers and connecting to my prototype's JTAG? I can't find any documentation on the function of these links- One other thing (assuming this can be done) my 'external' prototype board uses a str9 device- Is there anything 'device specific' about the actual embedded Rlink board, considering it's from an STR7 Starter kit, or is it only the daughter boards that plug into the mother board that are different between STR7 and STR9 REva kits? Many thanks David |
STR9 uses RJTCK (return JTAG clock) pin, that is not in use for STR7 devices. Check the connection of this pin on the header...
Hi,
Yes, you can use the RLink that is on the REva with other boards, if the version of REva is 2.10 or lower.
You just need to detach the RLink. Or you can remove the daughterboard and all jumpers from the eval part of the board. You must keep the 2 jumpers on the RLink itself. There should be more information on this here:
"help"->"PDF"->"STRx-Tools"->"REva"
The RLink for STR9 is the same as the one for STR7. You can use it. It does not use RTCK, as Opijozko said, but you can reduce its clock speed manually if needed. You'll find more information on this here:

Best Regards,
