Just verified this happens only on the MAC and not on an Ubuntu machine!

Hi,

what does this mean?

"Unable to reproduce this using sample apps i know."

Please try to reproduce the issue using a minimal patch to an existing zephyr sample or test.

You could also try to find out what MBEDTLS_PLATFORM_STD_SNPRINTF is being defined to be, that might give a clue to what is going wrong. This could be done by building verbosely and then copy-editting the command that files with the flag "-E" (this will run the preprocessor only, allowing one to inspect the MBEDTLS_PLATFORM_STD_SNPRINTF symbol).

which gnuarmemb version are you using?

[karthikprabhu17]

@galak sorry for the delay in response. I am using gcc-arm-none-eabi-7-2018-q2-update. I was able to get rid of the error by removing MBEDTLS_PLATFORM_STD_SNPRINTF from config file. Although that is not solution i know!

[galak]

Sorry for taking a while to respond, can you let me know how to reproduce?

[karthikprabhu17]

I just tried it...the master dos not have this problem . Closing this.
