i'm nagendra murthy, i'm developing code for STM32F427VITboard for blinking the led using keil. i'm facing the problem in solving this error *** error 65: access violation at 0x40023800 : no 'read' permission. i have connected the LED to port B pin no 14 and 15. program is running without errora and warning. but when i debug it. it is showing error mentioned above.. please help me..
i'm not using debugger. there is no provision given in the board to connect st link debugger. so can you suggest any other method to solve the problem.
Then get a board which does have debug access!! And use it!!
Seriously: trying to develop without the debug access is folly - you are deliberately tying your hands behind your back!

It's highly unlikely that bod even remembers making the post. If he's still working on his problem then he's got real issues.
