Subject: ST6 Programming Issues - Any one else.

We are observing a problem in recent times where we program ST62T30BM6 with
starter kit. The software we program into the unit returns a checksum for
the EPROM contents.
Product has been stable for months but now the checksum returned on about
90% of several batches of processor is incorrect when warmed up and the
product exhibits eradic behaviour when warmed. Part verifies in programmer
when hot though - it seems that internal reads are less reliable than
programmer verifies .
If the micro is programmed twice with same code all of the above problems
Two questions for the group.
Has any one else observed similar porblem ?
Has any one got the programming specification for ST6 micro's (ST do not
seem to provide on WEB) ?
