Exiting Wait Mode - F28069

Normand St-Jean

Hi all,

We have a board with a dipswitch connected to GPIO34.

When the position is ON, GPIO34 = 0
TRST is pulled-down, TRST =0 .
And, GPIO37 is pulled-up, GPIO37 = 1.

These conditions leads to WaitMode() on power-up, which we want to avoid, or, be able to exit.

Is there a way to leave WaitMode, without having to connect a debugger? Or, a wait to ignore the BootPin state? Or, any other solution that would allow application to start normally?

Thank you,

Normand

Hi Normand,

I'm afraid, below are the only ways how you can exit the wait mode:

In this case, we will use an adjacent GPIO.

I wish there would have been a warning about GPIO34. Unless the designer search for BootMode, there is no other indication about it. If there is, I did not find it yet, and please, point it out to me.

It seems that this GPIO should be configured as an input ONLY when we need to trigger Boot Mode. Otherwise, user will get undesired behavior, as we are experiencing.

Thanks Gautam!
