Introduction
It's possible to access avalon-MM bus with an USB-Blaster connected to jtag. To do that a special ip-core must be instanciated in Qsys and a system console must be launched in Quartus.
Instanciate Jtag-avalon-MM
Access avalon-MM registers
- Launch Systemp console in Quartus :
tools -> System debugging tools -> system console
- Connect to USB-BLaster JTAG-avalon-MM instance :
% set masters [get_service_paths master] % set master [lindex $masters 0] % open_service master $master
- Write 32bits value
% master_write_32 $master 0x4 0xdeadbeef
- Read 32bits value
% master_read_32 $master 0x0 2
