Segger undefined symbol: end

[grpnr]

Hi,

I'm trying to use a static library that I developed in example blinky app in segger studio and stuck in.First of all,I compiled my source code on debian with arm-none-eabi-gcc,-specs=rdimon.specs. Then I added the static lib to segger studio, also added the libs under arm-none-eabi/newlib (libc.a,libg.a,libm.a,librdimon.a) to Project->Options->Linker->Additional Input Files.

So that some linker errors has gone out, except one:

 undefined symbol: end

After some digging in newlib, I figured out this symbol in librdimon.a and  Arm GNU Toolchain 4.9.3 says

If you used nosys.specs or rdimon.specs, it may expect symbol 'end' to be defined to denote the HEAP start. Define symbol 'end'.Refer "12. How to update linker scripts for syscalls?" for examples.

I couldn't find any resource how to handle this in ses.

Thanks in advance

Hi,

I'm not sure why the end symbol needs to be defined. But I would suggest that you try using the same compiler/linker flags that we use to build the uECC library in \nRF5_SDK_12.3.0_d7731ad\external\micro-ecc\nrf51_armgcc\armgcc 

Segger projects which include this library can be found in SDK 14.2.0 and later, but only for the nRF52 series.

It seems one of my dependencies is not compatible for nrf51 series.

Thx for response
