Posted on February 19, 2015 at 08:23hello everybody,
i am an electrical engineer working with stm32 devices these days.
i am having problems at programming stm32f030 via st link utility, i use IAR as an IDE, i have tried hardware troubleshooting, firmware update, downgrade but all in vain.
sometimes it connects and then disconnects at the very same instant, i have verified that the power lines, vcc/gnd signals are ok and intact, i have even tried to view the fluctuations if any via oscilloscope but nothing bore fruit.
for programming i m using an stm32discovery board, using its st link tool while using VDD,SWCLK,GND and SWDIO signals.
please help me track down the problem.
appreciate all the help.
thanks
