Hi,

Using EA LPC11U35 QuickStart Board, I can't work "mbed-os-example-blinky-baremetal".

Build output error : Warning: L3912W: Option 'legacyalign' is deprecated. Warning: L6320W: Ignoring keep command. Cannot find argument 'os_cb_sections'. Error: L6218E: Undefined symbol _scanf_mbtowc (referred from BUILD/LPC11U35_401/ARMC6/mbed-os/platform/ATCmdParser.o).

I can not use mbed-os_5_bare-metal for LPC11U35?

Best regards,

Hi Shingo,

Thank you for your report!

I have reproduced this issue as well, using the ARM and ARMC6 toolchains. I have raised an issue in the repository on your behalf.

Note the the ^{Undefined symbol _scanf_mbtowc} has already been fixed (as described in the raised issue) and will be fixed once the Mbed lib will be updated in the example.

Note that using `GCC_ARM` doesn't raise a build error.

Regards,

Mbed support
