Solved W5500 10BASE-T compliance test: how to transmit continuous test data (min IPG / random / all-ones)?

Hello,We are running IEEE 802.3 10BASE-T transmitter compliance tests (Keysight N5392A software + N5395 test fixture) on our product that uses the W5500 with an ESP32-S3 host over SPI. We could not find a way to make the W5500 transmit the continuous test signals that some tests expect. We would appreciate advice on how WIZnet did this.Our setupPHY forced to 10BASE-T (PHYCFGR, auto-negotiation dis…

WizFi360 maximum payload size

I'm developing an application which requires sending files over TCP using a WizFi360. I seem to be having some success, but when I capture packets arriving at my server I find that the maximum payload sent appears to be 1024 bytes, with anything greater than that being fragmented. Whilst this is acceptable it is a little bit inefficient. Is there any way to increase the payload up toward 1460 Byte…

W6300 crystal selection

It’s a question related to the specification of the crystal that is used for the internal system clock on the W6300. In the datasheet the crystal requirements are shown in Table 10 Quartz Crystal, section 8.1, page 136. It gives values for the crystal parameters and the following equations to calculate the required trans-conductance, gmcrit. It also directs the designer to reference  htt…

W6100-io module RX TX ESD protection

Hello, we are developing a 100Mbps PoE test board using a W6100-io module and discrete Ethernet magnetics. We have experienced damage to the W6100 RX inputs during Ethernet cable insertion/removal and would like guidance on ESD protection for the PHY-side TX+/TX− and RX+/RX− signals. With the external ESD devices removed, measurements during normal Ethernet operation showed single-ended voltages r…

W5300 / Strange ARP response during UDP communication

안녕하세요 W5300 으로 UDP 통신중 문제가 발생하여 문의를 드립니다. 기본적으로 통신연결과 데이터는 잘 동작하는데 가끔 ARP가 생기면서 응답할때 간간히 문제가 생깁니다.문제될 시 의 아래의 캡쳐를 남깁니다. PC -> 장비로 데이터를 보내며 ARP응답을 잘 하게 되면 계속 통신이 되는데 잘못된 데이터가 오면 잠깐 ( 몇초에서 수십초 가량) 통신이 끈기게 됩니다.

Unable to Flash W7500P, Write Protected

Hello,I've run into an issue with the W7500P while flashing firmware. To start off I am unable to share the entire source code or schematic, but I can share sections of the source code and the schematic itself is functionally identical to the published reference schematic on the Wiznet GitHub; with the exception of GPIO pins being fanned out to headers, but these are unpopulated while I am testing…

W5500을 사용하는 중 PHY Link에 문제가 발생하고 있습니다.

현재 W5500을 이용하여 보드를 설계하였고 일반적인 동작은 크게 문제가 없습니다.다만 간헐적으로 부팅이 필요한 네트웍 장비와 제가 설계한 보드에 전원이 동시 투여 되었을 때피지컬 링크가 활성화되지 않습니다. 정확히는 네트웍 장비의 RJ45소켓의 링크에 불이 들어오지 않습니다.보통은 네트웍 장비가 부팅이 끝나면 피지컬 링크가 활성화 되고 통신이 문제없이 이루어지는데문제가 발생하면 제 보드 상에서 주기적으로 PHYLINK를 확인해 봤을 때 PHY_LINK_ON과PHY_LINK_OFF를 왔다갔다 합니다. LINK_ON에서 LINK_OFF는 약 5초, LINK_OFF에서 LINK_ON은 약 10초 정도 걸리는 것 같습니다.  이로 봤을 때 W5500과의 SPI통신은문제가 없는 것으로 보…

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.
