W55RP20-EVB-Pico Ethernet - GPIO 관련 질문.

안녕하세요,현재 W55RP20-EVB-PICO 를 사용해서 프로젝트를 진행중입니다. 현재 프로젝트 성격상 가용 가능한 GPIO 핀들을 거의 다 사용해야 하는 상황인데 Ethernet 을 사용하면 (Ethernet 관련 코드를 사용하지 않았을 때는 문제 발생 안 함) GPIO 0, 1, 4 의 세팅을 Ethernet 라이브러리가 가져가 버리는 듯 합니다. 물론, 이는 GPIO세팅을 다시 하면 되찾을 수 있기는 한데, Ethernet 도 계속 사용해야 하므로 지속적으로 GPIO핀의 상황을 체크해야 해서 조금 거추장스럽습니다. 이게 과연 의도한 현상인지 아니면 Ethernet 드라이버 관련 버그인지 알고 싶습니다.

W55RP20 SPI INT NOT GETTING TRIGGERED IN S2E

I am using W55PR20 EVB BOARD CONNECTED TO MCU AND USING SPI INTERFACE TO CONNECT TO W55PRO. USING STANDARD S2E RELEASE 1.23 FROM WEBSITE. i am able to see DEBUG MESSAGE COMING PROPERLY TO W55PR20 and the same is not coming to SPI. All options are explored , seeing SPI INT not getting triggered at all.  Need hlep.

W55RP20 - What is RP2040 GPIO 17 internally tied to

I am writing NON-Sdk code for this device.The documentation states: "However, GPIO17, GPIO20, GPIO21, GPIO22, GPIO23, GPIO24, and GPIO25 are not accessible due to the connections inside the board."I have found connections for GPIO20-25, but not 17.GPIO20-25 interface with the W5500 SPI.Nowhere does documentation or drawings identify the GPIO17 internal connection.Since the RP2040 code must initial…

W55RP20-S2E Long connection to MQTT

Hi everyone, I'm having a problem with the W55RP20-S2E module. The connection time to the broker is about 20 seconds, sometimes less, but usually 20 seconds.I'm wondering if this is normal?I've tested the device on versions 1.1.9 and 1.2.0, and they work similarly.I use three certificates to authenticate with the broker.I've analyzed the logs, and what puzzles me most is this fragment, which…

W55RP20-EVB-PICO + WIZPoE-S1 = Magic Smoke

Hi!I naively assumed that WIZPoE-S1 is a perfect non-isolated match for W55RP20-EVB-PICO.After programming, I unplugged USB, put WIZPoE-S1 in female headers (VC1/VC2 on RJ45 jack). I connected this combo to TP-Link TL-SG2008P (802.3at/af) and after 2 seconds and successfully power and Ethernet negotiation W5500 chiplet released magic smoke trough small hole in chip package (2 mm left from "W" in W…

How to resolve IP conflict when using multiple Wiznet devices with ConfigTool?

HelloI am working on a project that uses several Wiznet modules on the same local network & I noticed that when I scan them with ConfigTool; sometimes two devices show up with the same IP address. This creates problems because I can not reliably connect to the right device and occasionally one device becomes unreachable.I tried manually reassigning IP addresses through ConfigTool but after a r…

W55RP20-EVB-Pico high packet loss

I have recently bought a W55RP20-EVB-Pico board with the intention of adding support for it to the Zephyr RTOS.After some struggling (do I really have to use the PIO for SPI? What is the maximum SPI frequency in that case? I had to slow it down to 10 MHz.), I got it working, but I'm experiencing extremely high packet loss (>60%). It also takes minutes to get an IP address from DHCP as a result…
