In high voltage mode, for nRF5340 DK, which software should I use for log printing?

[Carl Sun]

Hello.

1. For nRF5340 DK, in normal voltage mode, I use putty(windows) and minicom(Ubuntu) to view the printk logs, it works fine.

In high voltage mode, which software should I use to view the printk logs? besides RTT Viewer?

2, is there some other C command to print logs for nRF5340? besides printk?

Thanks.

Carl.

Hello!

1. Serial logging should work fine with any terminal, even in high voltage mode. To get log output from the nRF5340 you must use either a serial interface or RTT. Any serial terminal should work.

2. In Zephyr you have the Logging API, which enables you to print logs of varying priority with the possibility of disabling logs when desired. Other than that you can also use classic C printf functionality as described in the Formatted Output documentation.
