"no target defined" error when building NUCLEO_F042K6 with GCC_ARM

[mbains]

Unable to build basic blinky for NUCLEO_F042K6 with offline mbed-cli (v0.9.1)

Steps to reproduce:

1. mbed import mbed-os-example-blinky
2. cd mbed-os-example-blink
3. mbed compile -t GCC_ARM -m NUCLEO_F042K6 -v

(env) manny@linux-wh4c ~/c/m/mbed-os-example-blinky> mbed compile -t GCC_ARM -m NUCLEO_F042K6  -v

I'm using gcc version 5.2.1 20151202 and mbed-cli 0.9.1 installed with pip

[0xc0170]

Target NUCLEO_F042K6 is not supported by rtos.

@0xc0170 Thanks. I should have read the release notes :-)
Any unofficial estimate of when it might get put in?

[bcostm]

Hi,
mbed RTOS is not compatible with this platform (code size is too big for this device).

[adustm]

Hello
It looks like this request won't happen and the issue won't be solved (target too small for the request).
Can someone close the issue, please ?
Cheers
