Previous build of fesvr-zynq wouldn't recognize block devices with linux built from firesim-software@023ef56. New build works with firesim-software and the prebuilt linux included in uramdisk.image.gz. Below are outputs from booting a rocket chip built with fpga-zynq@726eb97:

we successfully build the RISC-V based linux with the files you updated, however ,we cannot log in cuz we do not know the username as well as passwd, do you know why?

@greenhandbob try

user: root

sorry to bother you again,but that username and password is not correct

Are you able to login to linux with the uramdisk.image.gz from ucb-bar:master? The creds should not have changed on my branch. I only updated /home/root/fesvr-zynq and /usr/local/lib/libfesvr.so in the uramdisk.image.gz filesystem. You can perform the following to verify those were the only files I changed:

Download uramdisk.image.gz from ucb-bar:master branch and rename to ucb-bar-uramdisk.image.gz. Download the same file from heidecjj:master branch and rename to heidecjj-uramdisk.image.gz

mkdir ucb-bar
mkdir heidecjj

cd ucb-bar
dd if=../ucb-bar-uramdisk.image.gz bs=64 skip=1 | gunzip -c | cpio -i
cd ../heidecjj
dd if=../heidecjj-uramdisk.image.gz bs=64 skip=1 | gunzip -c | cpio -i
cd ..
diff -r --no-dereference heidecjj/ ucb-bar/

Maybe nobody knows the original passwd actually, however, there is one post has toturial to help us to change passwd in the armdisk.gz

thanks, anyway
