Hi,

We recommend using same the Segger embedded studio version as listed in the SDK release notes. It's a known issue that our bootloader is not compatible with the latest versions of GCC.

Also, as you have noticed already, the SDK code is not compatible with the Segger runtime library. The legacy library which is supported in our SDK was removed in SES v.6.20.

Best regards,

Vidar

Update - I just re-compiled the files using SEGGER Embedded Studio v4.22 instead of v6.34a and the DFU Update seems to be working now. Can someone else test this and confirm please? I would obviously like to use the latest SEGGER Embedded Studio version but this is a deal breaker. Just a little note that in v6.34a I had to disable the SEGGER_RTT_Syscalls_SES.c file since it was recommended by Nordic to do so.
