RCC_WaitForHSEStartUp() fails

Hello,

I am currently debugging my own Hardware that uses an STM32F103T8 and an 8MHz ceramic resonator for clock generation.

I copied the RCC_Configuration routine from one of the Examples (FWLib v2 / Smartcard) and the problem is that sometimes the routine does not correctly initialize the HSE because the RCC_WaitForHSEStartUp(); fails (timeout).

The oscilloscope shows a clean and stable 8MHz at the ceramicl so I am a bit helpless.

I am using Rowley's CrossWorks with the latest libraries and the latest STM32 FWLib.

Any ideas?
