RE: newlib vs SEGGER runtime Library cJSON library

Hello,

Nordic is not responsible for the libc implementation and what is supported. This is something you need to ask the developers of the toolchain about.

What you can try is either disable the newlib nano flag in the makefile, to compile the full newlib instead of the nano version, or you can find a workaround where you for instance print the uint64 number as two 32 bit numbers instead.

Hi,

Is there any answer to this? We are blocked by this in moving forward with our CI. I can provide some extra info on my environment:

- nrf5_sdk_17.0.2_d674dde using the embedded cJSON library

- GCC 9

RE: newlib vs SEGGER runtime Library cJSON library

I've also found this issue: https://github.com/DaveGamble/cJSON/issues/162 which seems to indicate uint64_t shouldn't even be supported under cJSON...
