Post by bftiedt »

i have tried all the steps i knw i can detect but it gives me all 0' for the value. So i tried the j200 jumper method with tap c and tap, even used the tap a ffffffff, and debug still wont come on. about the only think i have dont is shocked the hell out of myself 2 times now lol. im at a loss of what to try so any suggestions would be great.

DEBUG has to come on and if not you need to think
1. Do do the J200 properly?
2. Is the CPU completely dead?

Why solder? You must use jumper since you need to remove it once DEBUG goes on.

Use
"speed 2"
"tap c"
" tap a ffffffff"

With J200 on must give you the DEBUG ON.
Unless you have used the wrong jumper.
