 the EOMA-68 CPU card is actually a cut-down version of the EVK schematics.
 we picked the A10 not just because of the low projected price but also
because its interfaces are near-direct match for EOMA-68.

do not work, how you will search for the cause of the problem when there is
NO technical info for this processor?

know if it will work for you or not and I do not understand who will invest
thousands in development of product with not documented processor

Sooner or later the spec of A10 will be public, it's not public because
it's not carefully checked, the spec we use internally is very bad, some
part is missing, some is wrong or misleading. We are moving fast, the
documents fall behind.
