Hello,
After trying to reconfigure the flash memory on the Virtex7 FPGA with a new
image, I am no longer able to connect to the SKARAB through casperfpga
using the 1GigE port. When I enter the command fpga =
casperfpga.SkarabFpga('169.254.128.213'), the following is output.
DEBUG:casperfpga.casperfpga:169.254.128.213: now a CasperFpga
DEBUG:casperfpga.skarab_fpga:Retransmit attempts: 0
DEBUG:casperfpga.skarab_fpga:Waiting for response.

ERROR:casperfpga.skarab_fpga:Socket timeout. Response packet not received.
My thinking is that the firmware image loaded into the flash is corrupt and
now the 1GigE port is disabled. Are these any other possible ways to load a
firmware image into flash without using the 1GigE port, such as the USB
port or JTAG header? If so, what would be the required procedure to do so?
Thanks,
Mark Peryer
