Detailed Description

ICARUS OS Error Handling Implementation.

Version

0.1.0

Provides system-wide error handling for unrecoverable faults. The Error_Handler enters an infinite loop with interrupts disabled to prevent further system corruption.

Error Recovery:

The Error_Handler does not return. System recovery requires:

• Hardware reset (NRST pin)
• Power cycle
• Watchdog timeout (if enabled)

Function Documentation

Error_Handler()

void Error_Handler

(

void

)

System error handler for unrecoverable faults.

Called when a fatal error is detected that cannot be recovered. Disables all interrupts and enters an infinite loop to prevent further system corruption.

Typical Callers:

• HAL initialization failures
• Clock configuration errors
• Peripheral initialization failures
• Stack overflow detection (if enabled)

Warning

This function never returns!

All interrupts are disabled - watchdog will not be serviced

Note

For debugging, set a breakpoint on this function to catch errors

Consider adding LED blink pattern for field diagnosis
