Configurations

Each configuration is maintained in a sub-directory and can be selected as follow:

tools/configure.sh thingy53:<subdir>

Where <subdir> is one of the following:

composite_cpuapp

NuttShell configuration with support for CDC/ACM with RNDIS composite driver.

nsh_cpuapp

Basic NuttShell configuration for the application core (console enabled in UART0, exposed via J-Link VCOM0, at 115200 bps).

nsh_cpunet

Basic NuttShell configuration for the network core (console enabled in UART0, exposed via J-Link VCOM1, at 115200 bps).

Flash & Debug

Both flashing and debuing is possible only with an external debug probe.
