Describe the bug

I have a new board SAMD21 M0 size as Arduino UNO, compatible with Arduino M0, native port, with ethernet shield Wiznet W5100.
I tried example code Hello World, edit all serial.print to serialUSB.print and load to cpu over Native USB port, I have selected Arduino M0 board in Arduino IDE. Then, I get this from serial monitor:

I have a company network on 192.168.0.x with DHCP. Before, this shield I used with MEGA and webduino, working.
Thank you.

This means the W5100 board is not connected correctly and is not initialized.

[EWS] Board : SAMD Zero , setCsPin: 10

Show how you connected (M0 pin <-> W5100)

[khoih-prog]

Try the simplest WebClient example from Ethernet library and be sure working before moving to more complex libraries and examples.

I'm closing the issue now, and won't reopen until you prove this is a bug of this library.

[proasnet]

Thank you for reply. I tried this with SAMD21 M0 board and with Arduino UNO. Both with the same ethernet shield Wiznet W5100, Arduino original shield and WebClient example from Ethernet Library.
In this both cases, I only remove shield from the first to the second CPU board. In HW, nothing else.
For SAMD M0, I must edit all Serial. to SerialUSB. for usb serial monitor, nothing else.
I tried an external power supply for board, without any effect.
I'm starting to wonder if the Wiznet 5100 is compatible with the SAMD21 M0, but I don't have another ethernet shield at the moment

This is monitor from UNO:

     #define BOARD_TYPE      "SAMD Zero" 
   #elif defined(ARDUINO_SAMD_MKR1000) 

If not working, you have to connect directly from ICSP connector of W5100 to M0 pins according

W5100 ICSP	<--->	M0
MOSI	<--->	23
MISO	<--->	22
SCK	<--->	24
SS	<--->	16
VCC	<--->	5V
GND	<--->	GND

If not working, you can ask on Arduino Forum for help (M0 card bad SPI pins, M0 bad ICSP connection, etc)

Good Luck,

[khoih-prog]

You can also try the new EthernetWebServer v2.2.1, which will try to auto-select the SS/CS pin according to board package

---

Releases v2.2.1

1. Auto-select SPI(s) SS/CS pins according to board package if available
2. Update Packages' Patches

The third step, I can not found this pins 16-23 on the board.
Board has pins D0-D13, AREF, SDA, SCL, A0-A5 and ICSP, where is W5100 connected currently.
Thank you.

[khoih-prog]

Hi @proasnet

It seems that your SAMD21 M0 board's ICSP is not compatible with your W5100 SPI bus. I don't have that kind of weird board to test and help.

If you have the multimeter, you can check the M0 ICSP is connecting to which pins.

The remaining way is to read the docs, ask around the Arduino Forum, to match the SPI pins 23, 23, 24 and 16 to your SAMD21 M0 to D0-D13, AREF, SDA, SCL, A0-A5

Somewhere you can find the SPI pins used for that special M0 board.

[khoih-prog]

You can compare with the schematic at

https://robotdyn.com/pub/media/0G-00005517==SAMD21-M0/DOCS/Schematic==0G-00005517==SAMD21-M0.pdf

https://robotdyn.com/pub/media/0G-00005517==SAMD21-M0/DOCS/PINOUT==0G-00005517==SAMD21-M0.pdf

[proasnet]

Its the same
arduino-M0-schematic.pdf
I only found that this board HW-819 is compatible with Arduino M0. I not found schematic from producer of my board HW-819.
I wonder if the SAMD21 G18 CPU needs to define SPI with the help of SERCOM, but I have no experience with it yet and I can't do it. Yesterday I solved SERCOM for UART on my board, because I need 4xUART for my project and so far I'm just trying to set it up. I'm not an advanced programmer, you can say that I'm still a beginner.
.

[khoih-prog]

For M0,

Pin 10 <=> PA18

Pin 16 <=> PB09 <=> A2
Pin 22 <=> PA12 <=> MISO
Pin 23 <=> PB10 <=> MOSI
Pin 24 <=> PB11 <=> SCK

With your latest test, it seems that M0 is communicating OK with W5100 (no more no chip error).

Possibly M0 is bad (SPI, etc.) It's better you buy W5500 and connect directly to M0 to try.

I suggest you use RP2040 + W5100S or W5500, such as WIZNET_5500_EVB_PICO, WIZNET_5100S_EVB_PICO. More powerful and integrated.

[proasnet]

So, my next experimet was, that I use a example Ethernet 2.0.1 library, WebClient, this working.

Good news, I'll check why we have M0 problem getting correct IP address.
Possibly recent update in Ethernet_Generic v2.4.0 is not compatible with Arduino SAMD core ???

Releases v2.4.0

1. Using raw_address() as default instead of private IPAddress data
2. Add missing LibraryPatches for ESP32
3. Update Packages' Patches

If you're willing to spend some time to help test and fix the bug (as I currently don't have the same SAMD21 M0 board), I'll reopen this issue.

---

Steps to test

1. Install Ethernet_Generic v2.3.1 to replace Ethernet_Generic v2.4.0
2. Use the same example code of this latest EthernetWebServer v2.2.1
