This bit of code seems to do the trick:
```
function getClockSource() {
  return ["NONE","LSE","LSI","HSE"][((peek32(0x40021020)&768)>>8)];
}
getClockSource();
```
It'll report what the clock source for the oscillator is currently set to.

Is it one of the older boards you have then?

function getClockSource() {

return ["NONE","LSE","LSI","HSE"][((peek32(0x40021020)&768)>>8)];
}
getClockSource();

Yes, I have a version 1.3b. One of the first boards I guess?

Your code reports "LSI" so I guess that means the Low-speed internal (LSI) RC oscillator is active?

I will solder the crystal now and see what happens.

Thanks!
