Hi to all
I am porting my code from LPC1114 to LPC11U37. The code, that uses UART, compile and works well under LPC1114. On the new processor the code compile correctly and works well except when I attempt to enable UART1. In particular if I set :

LPC_IOCON->PIO0_18 = 1; // PIO0_18 is RXD
LPC_IOCON->PIO0_19 = 1; // PIO0_19 is RXD

In order to config the usart1 pins, it compiles, but when I start debugging the result is:

15: Target error from Commit Flash write
Flash verify operation failed.

And I can't debug. if I comment the two lines, it compiles and downloads well (and, of course, doesn't work usart 1....) allowing me to debug.
There are some other settings ?
Thanks

What version of LPCXpresso are you using? You should be using v5.1.2.

If you still see problems with LPCXpresso v5.1.2, please can you post the full debug log:

It would also be worth trying a mass erase before programming, to see if that cures the problem:

Can you also confirm if you see the same problem with all images, or just this particular one. For example if you create a "semihosting" project using the project wizard, do you see the same problem?
