Read from memory

Hi,

Yes, Because I modified the design from JTAG to JTAG Bridge.

I'm trying to see if any communication can be done, and let you know.

Regards.

Hi,

When I execute tcl scripts, I get these errors:

Error: Failed to read data from FPGA memory. Result: ERROR: JTAG communication error is detected. It can be caused by the hardware failure and signal integrity in the JTAG chain. Try to restart.

while executing
"error "Error: Failed to read data from FPGA memory. Result: $result""
invoked from within
"if {$data_from_fpga == ""} {
error "Error: Failed to read data from FPGA memory. Result: $result"
} else {
puts "Debug: Data read from FPGA at..."
(file "receive_altera_FPGA.tcl" line 72)
------------------------------------------------

Error: Error executing TCL script:
------------------------------------------------
Error: Failed to read data from FPGA memory. Result: ERROR: JTAG communication error is detected. It can be caused by the hardware failure and signal integrity in the JTAG chain. Try to restart.

while executing
"error "Error: Failed to read data from FPGA memory. Result: $result""

} else {

Note that when I execute the script, I see that RX and TX LEDs inside FPGA near JTAG are flashing.

Please find attached the tcl file in text format.
