Hello,

i have a problem with debugging. I’ve had it the second time in two days, the first time i could just create the project anew and dodged it. This time my project is larger...

The first message i get when i build my project and try to debug it:

No source available for “(gdb0.proc42000.threadGroupi1,gdb0.proc42000.OSthread1).thread1.frame0”

If i restart the debugging process i get:

No source available for “0x2b061a1a”

Debugging worked before and i didnt changed any settings, but what i think i did:

The debugging worked and i placed some breakpoints. I recognized i needed a DMA and added it with CubeMX. I generated the code and refreshed eclipse. The breakpoints were gone. I modified the source a little more, Tried to debug it and got the error.

- The debugging with other projects is working

- Build configuration is debug

- Tried the usual stuff like cleaning and rebuilding and restarts...

The compiling process throws this warning:
f:/ac6_systemworkbench/plugins/fr.ac6.mcu.externaltools.arm-none.win32_1.7.0.201602121829/tools/compiler/bin/../lib/gcc/arm-none-eabi/5.2.1/../../../../arm-none-eabi/bin/ld.exe: warning: cannot find entry symbol Reset_Handler; defaulting to 08000000

So i checked after the startupfile and found it under:
\Drivers\CMSIS\Device\ST\STM32F7xx\Source\Templates\gcc\startup_stm32f746xx.s

I would be thankful for any suggestions!!!

UPDATE:

I created the same Project with CubeMX at another location, replaced all source- and headerfiles with the ones from the other project, included all folders and i can debug again.
Had again to change something in CubeMX, generated the code and hitted debug.
The same Problem, this time without breakpoints!
