Update to S310 V2.0.1 can't debugg

[Frederic]

Hello,

i want to update the softdevice S310 V1.0.0 to version V2.0.1. My applicatio based on SDK 6.1. With S310 V1.0.0 all works fine. But i can't update to S310 V2.0.1. I use Eclipse with GCC compiler.

I have adjusted the Flash size as described in "s310_nrf51422_2.0.1_migration-document" document and copy the new header files from S310 V2.0.1 into my project. The application don't run at all. I can't set a breakpoint at the start of the main function. Did I forget something? Is the softdevice S310 V2.0.1 just compatible with SDK 7.0 or higher?

The new S310 can be used in SDK 6.1 by following the migration guide you mentioned, and from you description it sounds like you have done all the necessary steps.

I tried here on my end with the ble_ant_app_hrm from SDK 6.1 compiled with gcc for s310 v.2.0.1. It worked after replacing the API headers, adjusted flash size, and added the sd_ble_enable call().

For debugging part, did you remember to set compiler option -g3, and also remove -O3? This is something at least I've missed before as I'm used to the makefile.common used in most of the SDK 6 examples.

Without -flto -fno-builtin, same behavior as before. If i start a debugg session the main function is never reached. If i suspend the debugg session, the application is in HardFault Handler. After a power on cycle (without debugging) the program starts normal.

Very strange, perhaps something in Softdevice has changed and i have to adjust my debugging settings but i don't know which settings I must adjust.
