Original author: acorn (source: https://github.com/chcbaram/wiznet-w7500-surf5) ## Components - **WIZnet Surf5** x 1 ([docs](https://wiznetshop.io/product/detail.html?product_no=1087&cate_no=1&display_group=3)) - Software: **microsoft VS Code** ([docs](https://code.visualstudio.com/)) ## Documents and links - [Blog](https://blog.naver.com/chcbaram/223280848156) (schematics) ## Article [WIZnet W7500 SURF5] - Create LED project Based on the existing STM32 project, we created a basic project as follows. ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701608181%2Epng) The HAL driver and CMSIS code provided by WIZnet have been added to the library. ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701608497%2Epng) The linker script and startup code were modified from those used in STM32. ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701608518%2Epng) The default memory configuration is as follows. The SRAM is not large at 16KB. ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701608402%2Epng) The STM32's startup code calls the SYstemInit() function, and in the code provided by WIZnet, this function includes system clock settings. ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701608563%2Epng) ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701608586%2Epng) I changed the external crystal frequency and PLL_VALUE value in the w7500x.h header so that the MCU default clock is 48Mhz. ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701608627%2Epng) In the bspInit() function, set the system tick timer to run every 1ms to be used as a reference for the operation of the delay() and millis() functions later. ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701608652%2Epng) Variables used in systematic interrupts are used in the delay() and millis() functions. ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701608663%2Epng) Add basic information for LED driving in led.c and initialize using HAL functions provided by WIZnet. ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701608670%2Epng) ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701608694%2Epng) These are HAL functions for GPIO control. We added code to control GPIO using these functions. ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701608722%2Epng) I added test code to make the LED blink every 500ms. ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701608726%2Epng) In the build options, change the MCU core used to cortex-m0 and modify the options because there is no hardware FPU. Also, -Wno-comment was added to WIZnet's HAL driver code to eliminate warnings. ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701608742%2Epng) The build proceeds normally. ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701608750%2Epng) The W7500 chip used in the SURF5 board is a SoC developed by WIZnet and includes a Cortex-M0 core. In order to debug with a debugger such as STLINK, it must be supported by a tool such as OpenOCD, but it is not yet supported. ​ And WIZnet provides FLASH downloadable firmware for the KEIL compiler. If you download the file with the FLM extension from the link below, you can use it with the KEIL compiler. Create a WIZnet.W7500_DFP.1.0.0 folder under the tools folder and copy the Flash folder and the firmware file for downloading W7500_128.FLM provided by WIZnet into it. The WIZnet.W7500_DFP.pdsc file is the CMSIS-Pack configuration file, and related content must be added here. ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701609381%2Epng) The full contents of the XML file are as follows. ```plaintext Nuvoton https://github.com/OpenNuvoton/cmsis-packs/raw/master/Nuvoton_DFP/ NuMicro_DFP Nuvoton ARM Cortex-M NuMicro Family Device Support First Released WIZnet Device Support Device Family Package W7500 W7500 The WIZnet W7500 Series 32-bit microcontroller ``` Now, let’s check with pyocd list using pyocd and the CMSIS-Pack folder created above. ```plaintext pyocd list --targets --pack=tools/WIZnet.W7500_DFP.1.0.0 ``` You can see that the W7500 chip is supported. ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701609459%2Epng) If you only want to download firmware to FLASH, proceed with the command below. ```plaintext pyocd load -t w7500 build/wiznet-surf5-fw.elf --pack=tools/WIZnet.W7500_DFP.1.0.0 ``` ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701609467%2Epng) I tested the board by connecting the SWD pins to a STLINK compatible product. ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701609484%2Epng) For debugging in VSCode, I added pyOCD to the launch.json file. To use the added CMSIS-Pack, specify the location in the --pack option. ```plaintext "configurations": [ { "cwd": "${workspaceFolder}", "executable": "./build/wiznet-surf5-fw.elf", "name": "Debug with PyOCD", "request": "launch", "type": "cortex-debug", "runToEntryPoint": "main", "showDevDebugOutput": "none", "servertype": "pyocd", "serverArgs": [ "--target", "w7500", "--pack", "tools/WIZnet.W7500_DFP.1.0.0" ], "windows": { "gdbPath": "${env:ARM_TOOLCHAIN_DIR}/arm-none-eabi-gdb.exe", }, }, ] ``` When you start debugging, FLASH is downloaded and debugging mode begins. ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701609516%2Epng) You can see that debugging starts normally. You can now debug your board while adding breakpoints. ![](https://maker.wiznet.io/upload/ckeditor5/462689943%5F1701609523%2Epng) --- Source: https://maker.wiznet.io/Acorn_/projects/wiznet-w7500-surf5-led-project-production/
