1 year ago Quick update: I was able to fix the overlapping memory regions. The problem was in the keystone.json file from the firemarshal-keystone git. I deleted the qemu-args line, then it works. The host-init always checks out the v1.0.0 branch of keystone, I modified that to use the dev branch. This is the modified host-init.c
#!/bin/sh
set -e
if [ $(command -v cmake3) ]; then
echo "Using cmake3"
alias cmake=cmake3
fi
if [ ! -d keystone ]; then
git clone https://github.com/keystone-enclave/keystone keystone
fi
# set qemu -bios argument to bootrom.bin we will build
PWD=$(pwd)
sed -e 's#\-bios .*bootrom.bin#\-bios '$PWD'/keystone/build/bootrom.build/bootrom.bin#g' -i keystone.json
cd keystone
git checkout dev
./fast-setup.sh
. ./source.sh
mkdir -p build
cd build
cmake .. -Dfiresim=y
make patch
make bootrom
make qemu
make examples
The boot sequence in qemu still fails, however, at lest there is an error now. I am assuming that the same happens on the FPGA but without the error message.

Hi,
i am trying to run keystone on an Alveo 250 FPGA using Chipyard and Firesim. When I execute the workload, the boot hangs after
[ 0.249572] Serial: 8250/16550 driver, 4 ports, IRQ sharing disabledsimilar to #235. Firesim is in version 1.17.0 and FireMarshal is on the current master. I have tried several versions of FireMarshal, including thedevbranch as suggested in the documentation but it didn't help.I guess that the problem has to do with the memory layout. When I run the workload in qemu (
./marshal -v launch boards/chipyard/firemarshal-2/keystone.json), it fails with the following messageDo you know where it's going wrong and what I can do to fix it?
This is the entire boot log on the FPGA:
