I was wondering if someone could answer these questions for me:

- How many interrupt sources does the AM335x and/or AM437x have?

- How many software interrupt sources does sources does the AM335x and/or AM437x have?

- How many external interrupt sources does the AM335x and/or AM437x have?

- And finally how many non-maskable interrupt sources does the AM335x and/or AM437x have?

Thank you.

Thank you for the quick response Biser.

I have already checked those documents and I was unable to find what I was looking for.

Regards
Dan

AM335X Interrupt sources are listed in Table 6-1 from the AM335X TRM. AM437X Interrupt sources are listed in Table 8-1 from the AM437X TRM. All GPIO pins can trigger an interrupt, these are grouped in GPIO bank interrupts, two per bank. Both processors have one nNMI external interrupt pin.

According to the TRM, the AM437x has 211 interrupt sources and AM335x has 127 sources. But I'm still struggling to find out how many software interrupts are supported, how many external interrupts are supported, interrupts order of priority and if the interrupts are edge triggered or level triggered.
