GDB MQX K70 Segger

I am working with a K70 Target using MQX 4.1.1 and a Segger Jlink

Building using arm-none-eabi-gcc under Ubuntu 14.04

I am able to build MQX build the application, Link and debug using arm-none-eabi-gdb --tui application.elf


But I am frequently unable to step into (s) or execture through (n) functions - I can usually step into them using (si) - step by machine instruction.


But in many instances trying to (s) into or (n) over a function cause the processor to execute either until the next break point or until the program crashes


Any ideas would be appreciated


Mmostly I am debugging quite well but the need to set large numbers of break points where (s) or (n) would make life easier slows things down
