If you use RLink standard the

debugging is limited to 32 K bytes of code in Flash or RAM.

You must buy RLink Professional (buy an unlock key from Raisonance).

I know this is an old thread, but it may be worthwhile for me to post the solution. My BOOT0 pull down resistor was insufficient, pulling the pin down to about 60mV. I strengthened the pull down and all was well.

Hello,

I guess you are executing the bootloader. Check if program counter starts with 0x1F.... instead 0x08....

Bootloader execution explains also why your crystal pins are stuck, because bootloader doesn't use external crystal.

Best regards,
