Triple Rate SDI RX reconfiguration error on Stratix IV

935 Views

Hej there,

I am trying to set up a triple rate SDI RX core in my Stratix IV design, but when the standard is changed from 3G to HD or SD the reconfiguration controller (altgx_reconfig) indicates an error right after the very first data word (0x5000) at RECONFIG_ADDRESS_OUT 0x0 is received.

The altgx_reconfig is connected as shown below:

altgx_reconfig_inst : component altgx_reconfig

port map( RECONFIG_CLK => CLK,

RECONFIG_DATA => reconfig_data_internal,

RECONFIG_FROMGXB => RECONFIG_FROMGXB,

RECONFIG_MODE_SEL => "101",

WRITE_ALL => write_all_internal,

BUSY => busy_internal,

CHANNEL_RECONFIG_DONE => channel_reconfig_done_internal,

ERROR => error_internal,

RECONFIG_ADDRESS_OUT => reconfig_address_out_internal,

RECONFIG_TOGXB => RECONFIG_TOGXB

);
