Posted on May 17, 2011 at 12:25Hello all,
I downloaded arm-none-eabi-gcc (Sourcery G++ Lite 2009q1-161) 4.3.3 and tried the sample application from Lanchon's RC2 zip file in this thread - only LED is moved to RB1. But it does not work.
I even tried simple LED blink application (listing is below).
I am downloading the app by stm32 flash loader - so the chip works. I can read the data back. Does anybody have a clue what am I doing wrong ?
