I try to add printf() in qn908xcdk_wireless_examples_bluetooth_otap_client_att_freertos.

I just copy some code from qn908xcdk_rtso_examples_freertos_hello.

But I always get compile error "undefined reference to `_printf'"


Do you know how to add printf() in qn908xcdk_wireless_examples_bluetooth_otap_client_att_freertos ?


I use MCUXpresso IDE v11.0.1, QN9080SIP development kit.
