Mbed2 C++ SDK export 404 error

hello,
if i want to export the mbed2 sdk on this site:
https://os.mbed.com/users/mbed_official/code/mbed/export
for the nucleo f303k8 board and cmake-gcc-arm, i get an 404 error if i click on the export button.

HI,

I’m afraid mbed2 is no longer supported. You could try using the bare metal profile for Mbed 6.

Thanks
Anna
