Hi,

I'm having a problem building an assembly for zynq and zynq_ultra.
After the print out stating "Generating UUID, artifact xml file and metadata ROM file..." I get the following error messages:

•     On Zynq using OSP for zed with the platform project version of the fmcomms_2_3_scdcd card:
  

o  "Exiting for problem: Compressfile is too large for BRAM. Input is 727451, output is 10232."

•     On Zynq Ultrascale using custom OSP for ZCU102 with the platform project version of the fmcomms_2_3_scdcd card:
  

o  "Exiting for problem: Compressfile is too large for BRAM. Input is 726109, output is 10148."

They both start opt stage but fail complaining about a missing .edf file for the container (I assume because the bit above terminated?).
Building the same thing for xsim succeeds with a 5952 byte metadatarom.dat file.
I'm not familiar with this error message. I assume it's in ocpihdl as that's the only place I could find the word "Compressfile" in the source.
Any suggestions? I feel like I've seen the byte number that gets reported when this stage is successful at values above 10k before.
FYI, I've just ported this assembly and the components it uses from Geontech's OpenCPI 1.4 to current OpenCPI 1.7 (specifically the 1078-implement-fmcomms-support-on-zcu104-platform branch as of 2nd July).

Thanks,

Dominic Walters

Hi Dominic.

The XML for a bitstream goes to two places - one is at the end of the
file in clear text (ignored by bitstream loading),
and the other is in a compressed form into BRAMs that OpenCPI reads
out for various purposes like "ocpihdl get".
The error message is saying that the XML is large (727451 bytes) and
can only be compressed to 10232 bytes, which does not fit into the
BRAM for this purpose (which is 8192).

We have discussed a number of "smart" ways of dealing with this, but
none have been completely implemented yet.  There is not much
difficult about it, but this size has not been exceeded in a few years.

In the mean time, if you have a source release, you can simply change
the two constants for this:
One is in runtime/hdl/include/HdlDevice.h  - the constant ROM_NBYTES
The other is in projects/core/hdl/primitives/platform/metadata_rv.vhd

• the default for the romwords generic

I haven't tried this, but it is likely to work.  Try just doubling the
values.

I'll try to create an issue to track the real automatic fix for this.
