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

Question

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 source code and then copy both uf2 files generated from compilation, it is not working. Kindly guide me for how make compiled uf2 files working with device?

Please configure the build environment according to the "Development environment configuration" section in the ReadMe. pico-sdk version: 2.0.0 ARM GCC Toolchain: 13.2.Rel1 Additionally, please follow the instructions in Section 9.2 "Building on MS Windows" of the following document to set up the build environment: https://datasheets.raspberrypi.com/pico/getting-started-with-pico.pdf After building, you can run the program using the Boot/Boot.uf2 and App/App_linker.uf2 files.

Thank you Aimee0 for reply. I tried to debug as you suggested and what messages I received, given below: [INFO] main : Hello Bootloader assertion "!enabled || irq_has_handler(IO_IRQ_BANK0)" failed: file "C:/Users/abc/.pico-sdk/sdk/2.1.1/src/rp2_common/hardware_gpio/gpio.c", line 189, function: gpio_set_irq_enabled How to solve this error as I have not modified any of source code downloaded from the github zip folder.

Hi, I downloaded i.e. cloned using this command only: git clone --recurse-submodules https://github.com/WIZnet-ioNIC/W55RP20-S2E.git I again verify that my pico sdk version is 2.0.0 With all these setup its giving me errors.

Hi Aimee0, I have successfully compiled my S2E code. I bought Raspberry Pi debug probe for debugging purpose of source code. I use SWD connection between debugger and W55RP20 board. Using VSCode, i am trying to debug my S2E code which was compiled successfully. But as there are two .uf2 files viz. Boot.uf2 and App_linker.uf2, how to debug actual S2E application in vscode? My project application requirement is: S2E application (as already given) in addition with some GPIO handling (as per my project requirement) that are available on W55RP20 board. So I want to modify S2E source code and make some changes to handle some of the GPIOs as per my requirements. Could you guide me through this?
