I have a question about base addresses that I find in the tilegrid files
<
reces>
To my understunding those are frame addresses that should have the format shown in table 5-24 of Xilinx UG470
<
reces>
And I do can find them when I am looking at the frame organisation produced by the x-ray tools
<
reces>
What I dont understand is how I can see them in the raw bitstream or maybe how they are derived from it.
<
reces>
I think it has to do something with self incrementation but I am not sure how, Could someone give some aid towards that ?

reces: You should see the frame address writes if you enable PERFRAMECRC
<
daveshah>
tcl set_property bitstream.general.perframecrc yes
<
reces>
daveshah Thanks I will try that. But how can I see that without it ?
<
daveshah>
You can't because of the auto-incrementation you noticed
<
reces>
The needed information should be there since the tool is calculating it
<
daveshah>
Oh, you want to calculate it from prjxray?
<
reces>
oh so it starts counting frames after it sees the type2 package starting ?
<
daveshah>
I think that is what the yaml file is for
<
daveshah>
Yes it autoincrements after every 93 data words or however long a frame is
<
reces>
Project xray has it calculated in both bitstream to frames and fasm to frames
<
reces>
what I am not sure of is how it changes block type
<
reces>
In the type 2 packet is both `CLB, I/O, CLK (000), block RAM content

The block type is encoded in the upper bits of the address, per 5-24
