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-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…

CircuitPython

I'm trying to use the CircuitPython standard drivers for a w55rp20-evb-pico. Is this possible?Why do your CircuitPython examples use PIO rather than the built in SPI 0 bus?

how to make W55RP20-S2E-1.1.4 source code generated boot.uf2 and app_linker.uf2 files working

Hi Everyone,I am using w55RP20-EVB-PICO for S2E application. I downloaded ''W55RP20-S2E_Bin_Files_V114'' containing Boot.uf2 and App_linker.uf2 and at the same time I also downloaded source code for same i.e. ''W55RP20-S2E-1.1.4.zip'' folder from wiznet's github.When I directly copy downloaded Boot.uf2 and then App_Linker.uf2  in W55RP20, it is working. But when I tried to build/compile sourc…

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…

W55RP20-EVB-Pico / W550RP20-S2E Local host name

Hi, I am using the W55RP20-EVB-Pico (with S2E firmware) as a TCP server to provide data to a PC over networks from a serial device.Previously we used Digi Connect ME modules, where it was possible to set a host name for each serial device. The DHCP server pick up this name and it is possible to ping the serial device by its name as well as IP address.However, with the W55RP20, I find only the "RH"…

W55RP20-S2E DHCP address allocation status

Greetings, I am using a W55RP20-EVB-Pico with W55RP20-S2E firmware, controlled via separate MCU over RX, TX lines. I can enter command mode and use the commands, but I am looking for a way to detect when the device has successfully received an IP address from the DHCP server on the network (or report a failure if it doesn't get one).There is an operation status command "ST", but this only responds…

Ability to read RAW ethernet frames on W55RP20-EVB-PICO

Hi,Is there a possibility to read raw Ethernet frames on W55RP20-EVB-PICO using Micropython (or C)? Where we can find documentation with the list of available/supported methods and protocols?I was late to submit my ioNIC contest project, but still want to complete it.Kind regards,Nen
