Hi, I've a keil Ulink2 vers.2 I do not know why but I've the RESET wire always at ground so it takes my board always on reset. Help me please.
Thanks.
Yes if I remove the cable my board can run. Yes is original Keil ulink2. I use the lpc1115 uP. Is not the first Time that I use the ulink2 with the lpc1115 but now I do not know why now not work.
And you're sure there isn't a short across the pins of the 20-pin connector? Everything on the EAST side, except the top one, are ground.
Is this a custom board? Does the issue impact more that one board? Do you have a second JTAG pod you can try?
It's also conceivable you're damaged the pod, this can happen when bringing up new board designs if you get the voltages in the wrong places.
Think about what you did between the times things worked properly and when they started failing.
No wrong connection, I mesuared that the pin out of the uP on ulink2 that Makes the reset for swd is always 0 Vdc.
Looks like you need to buy another one then.
