Hi Harsha,
Sorry that my reply took so long. I have written some notes about
setting up casper here:
https://gitlab.utu.fi/kjwiik/casper-installation
*However* they may be outdated and please note also that eventually I
gave up installing the toolflow and we switched to using a virtual
machine where casper is preinstalled. It works very well.
If you need the VM (Virtualbox), send me a private email and I will send
the download link.
Good luck,
Kaj

Hi everyone,
While reinstalling CASPER toolflow for my project with MATLAB 2021a and
Vivado 2021.1, I encountered a known error mention by Prof Kaj Wiik that
is "Error: no such instruction: `endbr64'". for which the fix was - *mv
Xilinx/Vivado/2021.1/tps/lnx64/binutils-2.26/bin Xilinx/Vivado/2021.1/
tps/lnx64/binutils-2.26/bin.bak*.
In addition to this I encountered another error - /"gcc: fatal error:
cannot execute ‘as’: execvp: Too many levels of symbolic links
compilation terminated." /This arises due to improper installation of
build-utils and build-essentials, so to fix this the following has to be
followed:
First remove the binutils by
*sudo apt-get remove binutils*
This will remove binutils and parts of build essential libraries so
there after one need to reinstall these by
*sudo apt-get install binutils'*
*sudo apt-get install build-essentials*
*
*
Best,
Harsha
