Hi all,

Thanks to Dave I have made a big progress with this project

I can now see JTAG is working and send commands - working!!!

I just did adjustment to DE2-115 board (which altera chip is CYCLONE IV E) since the main chip and pins are totally different.

Also major changes with components on board (e.g. VGA is now only 8 bits, instead of 10 bits on older board, memory sizes are bigger, and Ethernet controller is different, and many more changes) - almost done with changes

Just wonder if I enter CYGWIN and do all process after command:

tcl> jtag_vir 0x1234

can't send the command:

tcl> jtag_vir 0x1111

like Jtag is closed and need all process from beginning ...

Also I could not implement all commands to TCL together, because when entering

$ quartus_stp -s

commands afterwards are not seen

attached example file that doesn't work

Thanks,

Roee
