Microblaze interrupt to PS

[abdulparis]

Hi all,

I am running Linux on PS (CPU_0) and I have a Microblaze Soft-core in PL part.

I would like to know if there is a way to connect Microblaze interrupt to PS interrupts. I could not understand why I can't connect MB interrupts to PS in Vivado. Here are my questions:

1) What is the proper way of connecting MB interrupts to PS ? 

2) How to write the interrupt handler in Linux

3) Is it possible to send MB application from Linux (PS) to MB on the PL ? (I can configure easily the bitstream but I was wondering if this is possible)

Thank you very much for your help. Any help/remarks would be appreciated.

Best Regards,

hi,

you can refer to the following XAPP for PL to PS interrupt. However the application are run in bare-metal OS

Hi,

To answer your questions

1) What is the proper way of connecting MB interrupts to PS ? 

>> The interrupts from MB (PL) to PS can be routed via GP ports at least.

2) How to write the interrupt handler in Linux

>> Refer to attached example in the link http://zedboard.org/content/dts-syntax-and-interrupts-pl-under-linux
