Vivado error in build of cl_dram_dma HDK example
Hi
I am trying to build the DMA-based HDK example (cl_dram_dma) on the FPGA Developer AMI on an EC2 instance. After several hours I hit the following (as recorded in my nohup.out file):
[centos@ip-172-30-0-87 scripts]$ ./aws_build_dcp_from_cl.sh -notify
<time passes>
[centos@ip-172-30-0-87 scripts]$ cat 20_08_18-135551.nohup.out

Please check '/home/centos/src/project_data/aws-fpga/hdk/cl/examples/cl_dram_dma/build/scripts/hs_err_pid112936.log' for details
[centos@ip-172-30-0-87 scripts]$ cat hs_err_pid112936.log
[centos@ip-172-30-0-87 scripts]$
Is this a known issue and are there any thing(s) I should be doing in order to prevent it from happening?

Hi,
You may be running out of available memory on your instance.
Given the large size of the FPGA used inside the AWS FPGA instances, the implementation tools require 32GiB Memory (ex: c4.4xlarge, m4.2xlarge, r4.xlarge, t2.2xlarge). c4.4xlarge and c4.8xlarge would provide the fastest execution time with 30 and 60GiB of memory respectively.
https://github.com/aws/aws-fpga/tree/master/hdk#getting-started
Please run the builds on an instance with larger Memory. Let us know if you continue to run into issues.
Thanks!

I am running a c4.4xlarge machine. I will try once more and if fails again I will up it to a c4.8xlarge.

I rerun of the design on the same c4.4xlarge machine was successful. I guess we can close this for now though it will be interesting to see if it crops up again.
