The
very successful TF-320AC will be phased out at the end of
2005. TF-320BC is a pin-to-pin compatible replacement for
the TF-320AC. It is based on the TF-331 which has been in
production for over a year.
Why
do I need to modify the software to run on TF-320BC?
Although
TF-320BC is pin-to-pin compatible to TF-320AC, there are some
minor changes that need to be made. This is because TF-320BC
provides additional functionality that are not available on
the TF-320AC. Taifatech has prepared a porting guide to explain
the changes that are needed.
What
changes do I need to make on the software to run on the
TF-320BC?
The
packet filtering on TF-320BC is different than that of TF-320AC.
Set bit bit 2 of register 0x720D to continue using the TF-320AC
filtering algorithm.
Program
execution is faster on the TF-320BC, if a program such as
flash erase uses a for-loop to count the time, then the
timing needs to be adjusted.
TCP/UDP/ICMP
checksum generation is turned on separately on TF-320AC,
they are turned on simultaneously on TF-320BC.
Please
refer to the porting guide for additional details.
