<p class="MsoNormal">Hello,<br>
<br>
if I build the pc686 BSP with --enable-rtems-debug activated I can't run any of the testsuites examples, but get the following error:<br>
<br>
$ qemu-system-i386 -append --console=/dev/com1 -no-reboot -serial stdio -monitor none -nographic -kernel ./build/i386-rtems5/c/pc686/testsuites/samples/ticker.exe

It seems to stem from rtems/bsps/i386/pc386/clock/ckinit.c:165:<br>
<br>
> bsp_interrupt_vector_enable( BSP_PERIODIC_TIMER - BSP_IRQ_VECTOR_BASE );<br>
<br>
because "BSP_PERIODIC_TIMER - BSP_IRQ_VECTOR_BASE" equates to 0xFFFFFFE0, but the subsequent assert on bsp_interrupt_is_valid_vector() only allows vectors between 0 and 16.<br>
The BSP still works with the option disabled, but it makes debugging more difficult.<br>
Does someone has some guidance on this problem. I could remove the assert in bsp_interrupt_vector_enable, but I am a bit hesitant with simply removing things from core files.<o:p></o:p></p>

<p class="MsoNormal">I suspect based on the other uses and math that this check is valid but that the calls to bsp_interrupt_vector_enable and bsp_interrupt_vector_disable in pc386/clock/ckinit.c should not be subtracting the BSP_IRQ_VECTOR_BASE. BSP_IRQ_VECTOR_BASE
is set to BSP_IRQ_VECTOR_BASE which is used in conjunction with IDT manipulation. The vector passed into bsp_interrupt_vector_*able directly corresponds to a source on the two i2859s (0-15). <o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>

<div>
<p class="MsoNormal">I would try deleting the subtraction in ckinit.c. The interrupt is likely already on so as written it is probably a NOP.<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">The similar subtraction in btimer.c is probably right because the benchmark timer is installing a raw timer and the math is subtracting from an IDT index.<o:p></o:p></p>
