library issue while using FRDM-K64F
Hello,
I am using RA8875 Display with the
FRDM-K64F the issue occurs when I use the menu library menu.h. If I compile my code the following error occurs.
.
Meanwhile, the error does not occur with mbed-LPC1768.It only occurs with FRDM-K64.
It should be noted that the code used is the example code provided
What should I do to void or fix the error?

From main.cpp delete:
extern "C" void NMI_Handler()
{
printf("\r\n\r\nNMI Fault!\r\n");
wait_ms(500);
NVIC_SystemReset();
}
It does not fit there (the others are error handlers, the NMI isn't an error handler), and in general it looks to me to be a leftover of some debug sessions.
On the K64F the mbed library already uses the NMI handler (to disable the NMI handler, before that quite some people had issues when it would lock up after accidentally triggering the NMI handler, which is effectively an InterruptIn which is always enabled), so since the main.cpp also uses it, there is a multiple definition.
Did you define NMI_Handler in main.cpp file? Where's your main.cpp file? A code snippet provided?
