Hi Amit,
I am assuming you are compiling a CASPER toolflow image and that you are
able to program the CASPER toolflow image on the SKARAB via the 1GbE? If
so, then your MTU sizes are fine and then it should work for the 40GbE as
well
You should have the following versions for the SKA-SA BSP as shown below
when you read back via python using casperfpga - please confirm:
In [9]: fpga2.transport.get_skarab_version_info()
Out[9]: {'emdedded_software_version': '3.4.0',
'golden_image': False,
'microblaze_hardware_version': '2.5',
'multiboot_image': True,
'spartan_firmware_version': '1.6',
'toolflow_image': False,
'virtex7_firmware_version': '2.5'}
If any of the above is different then let me know.
What version of casperfpga are you using? You should be using the latest
from devel branch https://github.com/ska-sa/casperfpga/tree/devel. I am
using this version:
In [2]: casperfpga.__version__ (this is the command to read back the
casperfpga version)
Out[2]: '0.4.4.dev508+devel.16fce79'
Please confirm if this is different then try update to the latest.
Kind regards,
Adam
