DMA error when running on AWS instance

[Rahul-Kande]

Hello,

I am trying to run the AWS F1 instance setup.
I am using f1.2xlarge instance type with AWS FPGA operating system.

I am following the instructions from here: https://github.com/PrincetonUniversity/openpiton#running-openpiton-simulations-on-f1-instances-in-aws-step-guide

But, when I run ./dma_os $FILE_LOCATION , I am getting the following error:

[root@ip-10-0-9-104 src]# ./dma_os $FILE_LOCATION 2020-06-10T18:13:24.765435Z, test_dram_dma, INFO, dma_os.c +65: main(): Checking to see if the right AFI is loaded... 2020-06-10T18:13:24.778029Z, test_dram_dma, INFO, dma_os.c +159: check_slot_config(): Operating on slot 0 with id: 0000:00:1d.0 2020-06-10T18:13:24.780280Z, test_dram_dma, ERROR, dma_os.c +212: dma_os(): DMA write failed 2020-06-10T18:13:24.780371Z, test_dram_dma, ERROR, dma_os.c +77: main(): OS DMA failed! 2020-06-10T18:13:24.780377Z, test_dram_dma, INFO, dma_os.c +87: main(): Memory initialization FAILED

here are the other things I did already:

1. I ran hdk_setup.sh and sdk_setup.sh from https://github.com/aws/aws-fpga.
2. I ran steps from https://github.com/Xilinx/dma_ip_drivers/tree/master/XDMA/linux-kernel

Hi Rahul,
You can check openpiton google discussion Forum and search for similar issues .
I remember of facing similar errors and fixed . I was able to Boot OS on AWS.
