Function Documentation

__neorv32_crt0_after_main()

void __neorv32_crt0_after_main

(

int32_t

return_code

)

"after-main" handler that is executed after the application's main function returns (called by crt0.S start-up code): Output minimal test report to physical UART

global_trap_handler()

void global_trap_handler

(

void

)

Trap handler for ALL exceptions/interrupts.

main()

int main

(

void

)

High-level CPU/processor test program.

Note

Applications has to be compiler with <USER_FLAGS+=-DRUN_CPUTEST>

Warning

This test is intended for simulation only.

This test requires all optional extensions/modules to be enabled.

Returns

0 if execution was successful

sim_irq_trigger()

void sim_irq_trigger

(

uint32_t

sel

)

Simulation-based function to set/clear CPU interrupts (MSI, MEI).

Parameters

[in]

sel

IRQ select mask (bit positions according to NEORV32_CSR_MIE_enum).

test_fail()

void test_fail

(

void

)

Test results helper function: Shows "[FAIL]" and increments global cnt_fail

test_ok()

void test_ok

(

void

)

Test results helper function: Shows "[ok]" and increments global cnt_ok

xirq_trap_handler0()

void xirq_trap_handler0

(

void

)

XIRQ handler channel 0.

xirq_trap_handler1()

void xirq_trap_handler1

(

void

)

XIRQ handler channel 1.
