Hi,
Thanks for your reply.

Scope is not showing any sine wave on both main oscillator and RTC oscillator. So i disabled main oscillator and enabled the internal oscillator in startup file and checked the firmware. But no difference it made.

Is there any other way for checking it?

I have verified the hardware schematic and PCB designs. No clue so far.

Hi All,
I have a custom board with LPC2388 with reference of MCB2300 board. After some struggle now i am able to download the code into board and verify it using Flashmagic.

My problem is that board is not coming up with the buzzer which i had enabled in software. I have another problem with the same board is that not deducting Ulink-ME j-tag with internal or external clock.

My first question is that if there is any problem with the on board external crystal, will the falshmagic programming possible?

Second question is that how to verify a crystal is working or not?
