I'm a student of University of Catania and I'm using IAR Embedded Workbench for ARM, v. 6.21, 32K Kickstart Edition on WIndows 7, for an university project to program a STM32F100XB board (using SWD Interface)

It worked all but a day, trying to flash a program it gave me the following errors:- Fatal error: ST-Link Connection error Session aborted!- Failed to load flash loader: C:\Program Files (x86)\IAR Systems\Embedded Workbench 6.0 Kickstart\arm\config\flashloader\ST\FlashSTM32F10xxxRAM6K.out- Failed to load flash loader: C:\Program Files (x86)\IAR Systems\Embedded Workbench 6.0 Kickstart\arm\config\flashloader\ST\FlashSTM32F100xB.flashCan you help me undestanding why and fixing it?Thank you,Best RegardsAmedeo MerloEdit: Stm32vl discovery board #stm32f100 #stm32-st-link-swd

I had this same problem and managed to track it to a particular USB port on my PC. Changing cables and/or ports may have been the solution for OP.
