Bertl: are there any tricks to debugging hdmi?

is there anything that needs to be done to enable the level shifter on the plugin modules?

morning folks!

we were trying to test the hdmi on the micro but somehow we werent able to measure the clock or data signal past that chip

before, there was signal present

we tried to short hpd to 5v in the cable

then HPD (sink side) which needs to be 5V

(not 100% sure about that though)

the hdmi clock?

is there a lower frequency bound to that clock?

k

hm...

I'm not sure about checks on the output, but as it is CML it wouldn't hurt to have a 50R termination on it as well

I used an HDMI passthrough with taps

ah nice, i see

I did design a break-out for HDMI, which might be simple enough to extend to a passthrough with SMA

thanks :)

so if you need something like that, I can easily adjust it, you just have to order and populate it

we will see

okay

The dev board has arrived!!

Right? I'm excited.

Something like C's "Don't free non-allocated variables or die" but for FPGA's?

off to bed, good night

jhlink: i would say try avoiding the xilinx / vivado block diagram stuff

I just really want to learn the basics that isn't bad advice ( e.g. always type cast the return of malloc ), and then start contributing. :)

jhlink: what? you cant compare rtl to sequential code

When learning something new, I don't know what I don't know. In the context of C, for the sake of example, I'd follow whatever is given to me because I don't know any better.
