@ -484,3 +484,27 @@ Configuration sub-directories
at apps/nshlib with the start logic at apps/examples/nsh.
NOTES:
1. This configuration assumes that we are loaded into SDRAM and
started via U-Boot.
2. The serial console is configured by default for use UART1, the
USB VCOM port (UART1), same as the serial port used by U-Boot.
You will need to reconfigure if you want to use a different UART.
3. NSH built-in applications are supported, but no built-in
applications are enabled.
Binary Formats:
CONFIG_BUILTIN=y : Enable support for built-in programs
Application Configuration:
CONFIG_NSH_BUILTIN_APPS=y : Enable starting apps from NSH command line
4. The RAMLOG is enabled. All SYSLOG (DEBUG) output will go to the
RAMLOG and will not be visible unless you use the nsh 'dmesg'
command. To disable this RAMLOG feature, disable the following:
File Systems: CONFIG_SYSLOG
Device Drivers: CONFIG_RAMLOG
