Description of defect

My device is LPC1768

Toolchain ARMC6 OR GCC_ARM

Mbed-os is mbed-os-6.6.0

I tried mbed-cli, mbed-studio and the online complier.

I Get the [Warning] @0,0: L3912W: Option 'legacyalign' is deprecated.

Hi Etan,

Thanks for raising this issue.

The google cloud example has been tested with K64F with Ethernet and DISCO_L475VG_IOT01A with WiFi, but any Mbed OS 6 targets with Internet access expected to work.

LPC1768 do not have the TRNG feature so it could not be possible to enable Entropy sources, either you have to try to build TLS without entropy sources refer Null entropy but it is not advisable due to the security reasons, and another problem is some of them already tried TLS in this target but end up out of memory issue. The google cloud is particularly used MQTT connectivity over TLS/wolfssl for encrypting data for security reasons. so it is less likely this example runs in LPC1768 target.

Reference: Someone already tried adding RNG for LPC1768 target: https://os.mbed.com/users/manitou/code/rng/.
