Hi,

Until yesterday I haven't got any problems to launch my code into flash memory with CooCoxIDE. STLink utility and STMStudio have worked well also.But this morning, I can't do all thius things :C:\CooCox\CoIDE>''C:/CooCox/CoIDE/bin\coflash.exe'' program STM32F407VG ''..../Desktop/test/Debug/bin/test.elf'' --adapter-name=ST-Link --port=SWD --adapter-clk=1000000 --erase=affected --driver=''C:/CooCox/CoIDE/flash/STM32F4xx_1024.elf''  

Error: Connect failed, check config and cable connection

STLink Utility says :No target connectedBut the com LED is ON when I connect my board on usb port... But when the CooCox IDE launcheds the message error, this LED is turned OFF. I don't understand what's this funky problem.I tried to plug BOOT0 with VDD but it makes nothing seemingly...Thks.

No idea ?

I tried with a new project on CooCox IDE... but it doesn't work.

Hi Dear

Try to hold the Reset button (on board) down and during this push the Erase button(on Programmer software like CoFlash) then after about 0.5 second free the reset button I solved you problem on my STM-32F407 Discovery this way :D
