on power on LPC1769, the code isn't executed

[pedromoreira]

Hi all, i'm testing LPC1769 on a LPCxpresso board, when I use debugger on IDE, the code is executed OK but when I power UP the board the code isn't executed, what is wrong?

many thanks

Hi, the original problem was produced  for a "printf()"  statement, deleting this instruction the problem don't occur. I think that the cause for this anomaly is that the debug module load  automatically the library that contain the code for the printf statement.

thanks

Hi, I´ve got the same problem. What is the cause for that?

On OM13000 it worked before.

My project is based on the uIP/ webserver sample.

This can be caused by an external reset being applied to the LPC11U35 debug probe on the board as the board starts up. The attached notes from Embedded Artists explain the problem and how to modify the board to avoid it.

I´m using the OM13085 eval. board and it seems to behave differently than the OM13000, which I used before.

Where can I find the information exactly?

Thanks

Its an attachment to my response above (the LPCXpresso1769 CD Rev D Product Note PDF file.)

What code are you running and on which board exactly (OM13085?)

Did you try this using periph_blinky from the LPCOpen package?
