wiznet 6100 (WZ610MJ Rev1.0) with arduino ethernet libraries
-
-
@andycadams2011 I've narrowed the problem down to the softReset() function call. it appears to return 0 when chip = 61.
console print:
update: I've further narrowed the problem down to this "ReadSYSR_W6100()" function call which evaluated to 255. It would need to be a value between 0-127 in order to break this do-while loop.
-
@andycadams2011 Please try this: https://github.com/Bearham/EthernetLibrary/pull/1. Remember that SPI CS should be connected to pin 9.
Best Regards,

@kamiltomaszewski That change did not solve the issue, I still get an error that the ethernet shield was not found. I've been calling Ethernet.init(9) in my program, which sets should set "uint8_t W5100Class::ss_pin" variable to 9 if im understanding the library correctly? (which is entirely possible that i'm not)
what else would be useful for me to provide?
-
@andycadams2011 What operating voltage of the GPIO pin sockets are you using: https://developer.sony.com/develop/spresense/docs/hw_docs_en.html#_setting_operating_voltage?
-
@kamiltomaszewski operating voltage is 3v3
after restarting it 3 times, it seems to have started working. The library recognizes the board, however It says that an ethernet cable is not connected?
-
@andycadams2011 it seems like the issue is with the Ethernet.linkStatus() call. should i be expecting these calls to work with the 6100?
I've tracked the issue down to this section of code, which evaluated to 6, which then returns LINK_OFF:
-
@andycadams2011 According to chapter 4.1.18 this is the correct link status checking: http://wizwiki.net/wiki/lib/exe/fetch.php/products:w6100:w6100_ds_v104e.pdf
Could you please try unplugging the cable and see what the return value will be? Also 6?
-
@kamiltomaszewski 6 was the value for 1 test. However after unplugging/plugging in power to the setup and reloading the code, it no longer recognizing the board anymore? it seems to be having intermittent issues so i'm going to go over my wiring and see if that's maybe an issue? would lowering the SPI speed help here? is it possible that the SPI speed of 14mhz is too fast for a setup wired up on a breadboard?
edit: 6 is consistently the value of the PHYSR register with and without a cable connected. which concerns me because according to the data sheet, bit 7 should be asserted with the cable unplugged?
-
@KamilTomaszewski it seems despite the issues with the misreported hardware status, i'm able to run the arduino chat server sketch successfully. do you foresee the misreported hardware status leading to any issues in the future with the ethernet library? if not, then this is probably working well enough for my project! Thank you so much for all of your help, i really appreciate it!
-
@andycadams2011 Could you please try to check the status link at the end of the application? After the connection is established.
-
@kamiltomaszewski it appears that after a client connects to the device that the linkstatus stops reporting that the ethernet cable is disconnected
