Hello,

argh, why is everybody using F1? Most of my interest in in the newer
families.
And than without HSE. Even on my development head, this configuration failed.

Please try SVN head.

Without any clock setting, especially HSE_VALUE, settup should automatically
use PLL_CLOCK = HSI and 24(F100)/36(F101/F105/F107)/48(F102) or 64 MHz
sysclock.

Bye
