I have been trying various configurations, most of which have worked
without any issue.
So far I have had no luck getting Firefox or Epiphany web browsers
running - the issue may relate to the app trying to create file(s) on
a read only file system.
I assume I have to somehow point these apps at RAMSDISK, or create a R/
W partition on the SD cards
Ping works fine, so I am pretty sure that network connectivity is OK,
and I can see a TFTP server running from a remote machine.
Any help appreciated.
