Hello, I have bought WIZwiki-W7500 board. I have a problem with own firmware. Original binaries are working - hardware test binary works, original blinky binary works. No problem.
But my programs are not working. For example blinky program. I try to compile it with mbed online compiler and with platformio (mbed) too. The program is working about 0.5 second after reset the board. Then, it is stopped. So, I see a small flash of LEDs and then nothing. I wrote simple program for serial communication - for example write Hello World to serial port. I only get 1 or 2 characters after reset. And, then program is stopped.
Do you have any idea?
