and so I cannot get past the opening display.

display, the icons are too tiny to be usable. I have created a large
320x320 logo for the opening screen and added image scaling to expand
the images in the taskbar. The expanded images are not great. If I
ever get past the opening screen, the same problems will exist in the
application toolbar and in the start window. These icons are not yet
scaled.
Bottom line: Not ready for prime time.

8) I have a Camera, but there is still no ISI driver. I am not sure what to
do with the camera. NuttX needs something like V4L to provide the
definition for what a camera driver is supposed to do.
I will probably develop a test harness for ISI, but it is of only
minimal value with no OS infrastructure to deal with images and video.

That is because in this case macros like BOARD_MCK_FREQUENCY are not constants
but are instead function calls: The MCK clock frequency is not known in
advance but instead has to be calculated from the bootloader PLL configuration.

The NxPlayer is a audio library and command line application for playing
audio file. The NxPlayer can be found at apps/system/nxplayer. If you

3. NSH Console Access.
This configuration boots directly into a graphic, window manage
environment. There is no serial console. Some initial stdout
information will go to the USART3 serial output, but otherwise
the serial port will be silent.
Access to the NSH console is available in two ways:
a. The NxWM provides a graphics-based terminals (called NxConsoles);
The console command line is still available within NxConsole
windows once NxWM is up and running. The console input is still
via stdin (the host terminal window), but console output will go
to the NxConsole terminal.
NOTES:
i) Later I plan to integrate a USB keyboard so that the
console input will come from a keyboard attached to the
SAMA5D4-EK.
ii) It would also not be a difficult task to add a serial console
as part of the NxWM console. That is an option if a serial
console is really necessary but is not currently planned.
b. Telnet NSH sessions are still supported and this is, in general,
the convenient way to access the shell (and RAMLOG).
As with the NSH configuration, debug output will still go to the
circular RAMLOG buffer but cannot be accessed from a serial console.
Instead, you will need use the dmesg command from an NxConsole or
from a Telnet session to see the debug output

5. Media Player
This configuration has the media player application enabled. That
player is still a work in progress and is only partially integrated
with the NxPlay as of this writing.
At present, the the WM8904 driver is not included in the
configuration. Instead the "NULL" audio device in built in to
support higher level testing (there are also some unresolved I2C
communication issues the the current WM8904 driver).
This configuration depends on media files in the default mountpoint
at /mnt/sdard. If you see the message "Media volume not mounted"
in the media player text box, then you will need to mount the media
volume:
a. You will need an (full size) SD card containing the .WAV files
that you want to play (.WAV is only format supported as of this
writing). That SD card should be inserted in the HSMCI0 media
slot A (best done before powering up).
b. Then from NSH prompt, you need to mount the media volume like:
nsh> mount -t vfat /dev/mmcsd0 /mnt/sdcard
c. Then if you close the old media player window and bring up a
new one, you should see the .WAV files on the SD card in the lis
box.
Currently the list box is not scollable. So you will be limited to
the number .WAV files that will fit in the existing list box (a
scrollable list box class exists, but has not been integrated into
the media play demo).
