Hi Simon,
But it seems irrelevant?
Yes, it's irrelevant.
Have you checked the stats if you run out of memory somewhere?
I have checked them, and there is certainly something wrong. After some
time, stats for memory seem to overflow, at least that's my impression.
At one point I have this:
MEM HEAP
avail: 60000
used: 13C40
max: 14340
err: 0
And next print (after 1 second):
MEM HEAP
avail: 60000
used: FFFC6480
max: FFFC6A80
err: 5
Sometimes, there is no error at all, just "used" and "max" seem to
overflow or something.
Also, I noticed that no matter which connection is made first, side
Zynq->PC is the dominant one. I even tried not to call tcp_output() at
all, but behavior is the same.
When only PC->Zynq side is active, memory stats don't change at all (
used: 240, max: 440), even though high throughput is achieved
(>900Mb/s). Only when Zynq->PC side is active memory consumption
increases considerably.
Actually, I'm too lazy to check out myself what the images contain.
But not too lazy to write out that many sentences. :) A picture is worth
a thousand words. I understand your point though :)
Best regards and thanks for helping me out,
Nenad
