Handling interrupt under eCos

hi,

i am evaluating ecos 2.0 on nios ii 5.0 (on windows 2000). for it i am using the port 'nios2ecos50.exe', obtained from download section of this forum.

i wanted to measure the interrupt latency, but not able to handle the interrupt. i have tried it with clock and pio buttons. but, the similar program is running on nios without ecos, there i am able to handle the corresponding interrupts generated by clock and buttons.

can anyone please clarify what may be the problem, and how can i rectify it?

with regards,

sanjay

Your program will need re-writing to run under eCos I am surprised that your program compiled and linked! The API&#39;s for registerring an ISR are different i.e. alt_irq_register is replaced by HAL_INTERRUPT_ATTACH. For more information you need to read the eCos documentation which is found in altera\kits\nios2\components\ecos\doc\html\index.html
