Sorry for my late response.
I missed your email because our forum site didn’t send me the notification of new post although I set “Notification” on this forum.
Anyway, please refer to my below answers.
When comparing he behaviour of the Wiznet WIZ107SR modle to our board, we see the module has the RJ45 LED blink as soon as the module is powerred even if no RJ45 cable is connected. On our own board on the other hand the LED does not blink after power up, and I verified with a scope the relevant signals are constantly high (LED off).
Is the W7100-S2E-100 IC that we purchaced supposed to be programmed with the same firmware as the Wiznet WIZ107SR Module?
Are we correct to expect the LED to blink when the W7100-S2E-100 is powered and no RJ45 cable is connected?[/quote]
[color=#FF0000]With only this symptom, I can’t guess what the problem is.
But with 2nd symptom, I’m sure that W7100A-S2E has a proper firmware inside and runs correctly.[/color]
On our board we had a design mistake, and the Ethernet signals were connected by mistake to an SGMII port of an Ethernet switch instead to a 1000/100/10-baseT port of the switch. I have made blue wire modifications to cut the connection to the SGMII switch port, and connect to magnetics + RJ45 using equal length blue wires (to Pulse H6062FNL transformer + Amphenol RJHSE-3081 RJ45 connector). After the modification, I wasn’t able to communicate to the WIZnet chip using the WIZnet config tool through an Ethernet RJ45 cable.[/quote]
[color=#FF0000]Could you search W7100A-S2E chip via ethernet with WIZ107SR Configuration Tool before this modification?
Anyway, I really want to look at the schematic of the part of Switch which it is connected to, from W7100A-S2E and H6062FNL including RJ45.[/color]
In an attempt to communicate to th Wiznet IC through the RS232 TX and RX, we have downloaded the “WizISP for iMCU W7100 software”, and were tryng to use a USB to serial donle to communicate to the TX and RX RS232 signals of our Wiznet IC. Un-fortunately the utility kept giving us a message " COM port synchronization timeout! The COM port will be closed! Please check your board and try again"[/quote]
[color=#FF0000]WizISP is a program for uploading the whole firmware including boot code and you need to input logic_0 to BOOTEN pin to enter ISP mode.
The reason why you got “COM port synchronization timeout!” is that you didn’t input anything to BOOTEN pin.
I strongly insist you not to make it enter ISP mode. If you do, then you may lose boot code of it and it will make your chip broken.[/color]
With your report, I guess that W7100A-S2E works properly but Ethernet part of your board still have some problem.
I want you to look at the schematic carefully again.
If you give another part of the schematic which I asked, then we may be able to investigate the reason of your problem together.
