[casper] Skarab programming error "Skarab has not come back after programming"
Hi! Casperities, I'm writing to you guys for question on Skarab upload and programming error. Now, we're trying to program some fpg file into the platform but it fails. The error shows "*ERROR 192.168.3.2 transport_skarab.py:755 - Skarab has not come back after programming.*" So, I have try on generate new fpg files with tutorial design without editing (in https://github.com/casper-astro/tutorials_devel.git ) and upload and program. After, when we upload and programm new fpg file from tut_intro, tut_40gbe, tut_hmc, it shows the same errors too (as shown in figure). On the other hand, it has no problem when we worked on tutorial by using the example fpg files which are provided within tutorial_devel folder. Also, it has no problem with new-generate fpg file from skarab_adc_test and tut_spec which we have to generate due to mezzanine site configuration. But there're some condition for our work that we have to generate new fpg file with our computer which has Ubuntu 20 OS due to our Ubuntu 18 OS has not enough resource to run on execution flow. So, I wonder that what is the problems. Could anyone suggest us about this please.

Hi ! Wes, Thank you for your immediate response and reminding me about this issue on 1GbE yellow block. It really helps!!

[casper] Question on Casperfpga python 3.8 version
Dear all,
Due to the upgrade of '*casperfpga*' library from python 2.7 to 3.8, I have
tried to upgrade my software to a newer version. But still got stuck on
problems that I still can't properly install and use it as I have followed
the information on
https://casper-toolflow.readthedocs.io/en/latest/src/How-to-install-casperfpga.html.
I have pulled '*casperfpga*' repository from
https://github.com/casper-astro/casperfpga.git on *py38* branch
During installation, I have found error, "*katcp==0.9.1 required tornado <5
>=4.3*". So, I have re-install it by define "*tornado<5*" in
requirements.txt and do pip install. Later, it shows another error,
"*circus==0.18.0
required tornado>5*", which circus is defined in *setup.py *
Later, when finish the installation procedure, I am able to import '
*casperfpga*' library, connect with my SKARAB hardware port. But I am
unable to upload and program firmware file (.fpg) to hardware with error
occured as UnicodeDecodeError: 'utf-8' codec can't decode byte 0x8b in
position 33033: invalid start byte as detailed belows

>From my opinion, I think the error might be occurred by the python library
installation, e.g. tornado version conflict with katcp and circus in
different direction. But I have already tried on install "tornado<5" and
"circus==0.16.0" (which the error of tornado version would not shown.) But
still got *'utf-8' codec can't decode byte 0x8b in position 33033: invalid
start byte* error with the casperfpga version shown as "casperfpga-3.4.
.*dirty*."
As an unexpert, I really don't know what is the root cause for this
problem. So, anyone please do suggest me about it.
Thanks a
