DHCP issue W5500

[xamanimran]

I am experimenting with DHCP and DNS example. I am using W5500 and Rp2040 pico board with SPI0. I want to use DHCP to get IP. When I build and drag firmware.uf2 file in pico-board. Nothing was displayed on the terminal. I have also changed the configuration to SPI1 but nothing works. I have tested it with circuit python it works fine for me. I want to use C/C++ SDK.

static wiz_NetInfo g_net_info = { .mac = {0x00, 0x08, 0xDC, 0x12, 0x34, 0x56}, // MAC address .dhcp = NETINFO_DHCP // DHCP enable/disable };

Hi @xamanimran,

Is there no output in the terminal program even if the device is reset after F/W upload?

Hi @xamanimran,

yes, there is no output on the terminal. Even the print statement at the start of main() function doesn't print. I have tried both MinGW and NMake toolchains for compilation.

Hi @xamanimran,

There seems to be a problem in the process of checking the version information of the chip.

W5100S is '0×51' but W5500 is '0×04'.

Can you try to fix below function(wizchip_check())?

• W5100S
  • function : getVER()
  • value : 0x51
• W5500
  • function : getVERSIONR()
  • value : 0x04

But if there's a problem while checking the chip version, the print should come out, but it's weird that it doesn't...

Yes, this is helpful but has not resolved the problem as I have identified an issue with wizchip_conf.h file.

when I changed the value to W5500 and hit the build button. It automatically convert to W5100S. I have deleted the build folder and tried again to build but it changed _WIZCHIP_ value to W5100S from W5500 . This mainly happens when I delete the build folder and build form start. But when I build with W5100S setting and then after that I change value W5100S to W5500 it doesn't changed back to W5100S but then several errors occurs as shown below.

I have also made some changes in w5x00_spi.c file as shown below.

Hi @xamanimran,

Did you fix CMakeLists files or other files?

'RP2040-HAT-C' is implemented based on 'W5100S', so there are some parts that need to be fixed to use 'W5500'.

Please refer to the below.

1. Fix patch file 'rp2040_hat_c-patch.cmake'

2. Fix 'CMakeLists.txt' in 'RP2040-HAT-C\libraries\' directory

3. Fix chip version check function → Done

Thanks @GiungKim. The issue is resolved after making the above changes in respective files in CMakefiles.txt, wizchip_conf.h and w5x00_spi.c. Now it works for W5500.
