lost embedded ST-Link on STM32F429I-Disco

Hi guys, i accidentally mapped the SDFileSystem-lib to SPI1 (PA_7, PA_6, PA_5) and lost the ability to use the embedded ST-Link :( i got an external ST-Link USB Dongle and already erased the chip in faith to gain the embedded ST-Link back, but without luck. Even flashing the "STM32F429I-Discovery_FW_V1.0.1" didn't do the trick.

anyone got an idea how to resurrect my embedded ST-Link ?

thanks in advance, Ingo
