Hi to everyone,
Could everyone who has a similar message in syslog, like the one below
please test the attached patch and see if it helps.
Problem is, that the firmware is downloaded and it seems that the last
packet (at least a packet at the end of the firmware) is not accepted
anymore. The download is failing then, without restarting the cypress CPU.
There is another problem with newer devices which can possibly be fixed
with a new firmware. Stay tuned.
