I have a new LPC1758 board who don't work correctly with XTAL.
When i use internal oscillator is OK.
When i use XTAL is not OK. Debug probe don't connect each time, serial is not at the good speed, ...

When i use the same software on a LPC1768 board it's OK. (The design is the same on XTAL part)
I try many capacitor on xtal, same.
The XTAL is 16MHz same as on the other board ...

I don't know where is the problem and i don't know what i can look for resolve this.

If someone have some suggest ?

Thanks, Philippe.
