In a latest firmware version 4.04 HW_TRIG behavior has completely changed making it backwards not compilant. I spent all day trying to find a fault in an application in which I had changed WIZ with 4.03 firmware to a new one with 4.04. The only place where the information about the modification is mentioned is in a table in download section where firmware can be found. The user manual does not state this at all.
First of all I think it is a very bad idea to introduce such modification in software making it so incompatible with previous version, without giving user a choice. I think the best way would be to upgrade config tool with a proper parameter.
Second thing is the user manual itself. Please update it.
Unfortunately whole this situation forces me (and probably others) to use older firmware with other bugs not fixed.
I apologize that our firmware update gave you the confusion.
But ‘HW_TRIG’ pin behavior has not completely changed, just function added for no-PHY link situations.
(The ‘HW_TRIG’ Pin behaves the same as before when normal PHY link situations.)
If possible, we recommands to use the new firmware because the no-PHY link detection function using ‘HW_TRIG’ pin is expected to be maintained in the future.
Thanks for your advises.
