After turning on the power switch (SW1) in NetSUME board, I only see the Power LED (LD10) on... in red and the DONE LED is off . I checked that JP1 is not shorted,and I pressed the button PROG in NetSUME board.
I think CPLD xc2c512 has been accidentally reprogrammed over JTAG although that is less likely.

After turning on the power switch (SW1) in NetSUME board, I only see the Power LED (LD10) on... in red and the DONE LED is off . I checked that JP1 is not shorted,and I pressed the button PROG in NetSUME board.
I think CPLD xc2c512 has been accidentally reprogrammed over JTAG although that is less likely.
The following command run at a terminal:
dsumecfg write -d NetSUME -f production_test.bit -s 0 -verify
Error information at a terminal is following:
Configuring FPGA...
FPGA configuration succeeded.
Erasing Flash: 0%ERROR: timed out after 25000ms while waiting for FPGA handshake
ERROR: FPGA handshake failed while erasing blocks blocks 0 - 5
In addition ,It is possible that I run the command:
djtgcfg erase -i 1 -d NetSUME
Can you help me fixing the CPLD in the board designed by your company?
A similar problem also was resolved in the forum as can be seen in the following scrren shot.
