Withe the I/O expansion board, the serial console can also be sued with
With the I/O expansion board, the serial console can also be used with
either a TTL-to-RS232 or a TTL-to-USB Serial adapter connected by CN1
pins 59 and 61.
The default baud setting is 115200N1.
To use the VGA display controller with stdout and stderr, you also
need to selection CONFIG_MAKERLISP_VGA=y in your configuration. This
enables a required VGA initialization sequence.

This enables a required VGA initialization sequence.
The PC terminal software should be configured as described in the
MakerLisp Putty HOWTO document: 115200N1 BAUD.
2. The eZ80 RTC, the procFS file system, and SD card support in included.
The procFS file system will be auto-mounted at /proc when the board
boots.
The RTC can be read and set from the NSH date command.

The SD card can be be mounted with the following NSH mount command:
nsh> mount -t vfat /dev/mmcsd0 /mnt/sdcard
NOTE: The is no card detect signal so the microSD card must be
placed in the card slot before the system is started.
STATUS:
2109-06-16: The basic NSH configuration appears to be fully functional
using only the CPU and I/O expansion card. Console is provided over
USB.
Added support for SPI-based SD cards, the RTC and procFS.
Added support for SPI-based SD cards, the RTC and procFS. There are
still a few issues at the end-of-the-day: (1) the SD card block driver
is not being registered, and (2) RTC does not preserve time across a
power cycle.
