Help! I have loaded the STM322xG_EVAL/Applications/FreeRTOS/FreeRTOS_LowPower demo project into my STM3220G-EVAL board. Every 500 msec the red LED flashes to show me that the CPU is waking from sleep but I am having trouble reflashing the board since the CPU keeps going to sleep. I am using IAR embedded workbench with an I-jet debugger. Any hints how to accomplish this?

Try strapping BOOT0 High. It will boot the System Loader ROM, not broken code you have downloaded.

See if there are connection options with the I-Jet, like ''connect under reset'', ''Enable debug in low power mode'' or similar.
