i hope u connect to pin 44 without boot pins shorted. otherwise u just make connection to the ground. well. pin44 should have 0 too bot from flash and 1 to boot from rom. normally its connected via resistor to the ground. i cant see in thus mess what is what. when u short boot pins you pretty much connecting pin 44 to 3v. donething is wrong there. blue led is just connected to 3v and should be always lit if power present. cpu cant turn it off. that means i make short cirquit somewhere.
