Re: Interrupt GPIO DM6446

Yes, I would expect it. I don't know what the maximum is for interrupts, but one every 0.2 microseconds seems rather extreme. What are you trying to do and can it be accomplished in a friendlier fashion? Cheers, Lloyd Hi We are triggering an interrupt on GPIO0, successfully and the

Interrupt GPIO DM6446

Hi We are triggering an interrupt on GPIO0, successfully and the ISR is being run. It is empty, that is it simply returns. We are observing / proc/interrupts to see the increment. The problem is that when we hook the DVEVM up to a (4-5Mhz) source rather than a simple switch we lose all

EMIF / CS3 interfacing

When interfacing FPGA to the DM6446 EVM EMIF do I need a bus switch on CS3 for my device or is this handled already by the CPLD (Altera MaxII)? Am I right in thinking simply accessing an address in the CS3 space will automatically assert the CS3 signal? I plan on only having 8 bits

GIOV_33 / DC2

Hi I want to use the GIOV_33 pins on DC2(9 bit) at around 5Mhz. Two questions: i) How are they enabled on DC2 and how do they interact with the Ethernet devices - I need ethernet at the same time, is this possible? ii) Is there already a module within the Linux kernel for these pins. I
