Re: [ECOS] SCC driver for 8xx PowerPC processors

["Frank Robbins" <frank dot robbins at analogue-micro dot com>]

I am confused Guy's..?

I updated the Redboot flash for Paul so he should already have the SCC1
running ???
This is already in the tree ....?

Have you tried the SCC1 with the current board updated Paul? Or am I having
a late night brain haemorrhage?
