I modified my code like below. Is this OK? But PHY communication still not work normally. Once I disable the " watchdog enable checkbox" it's OK while after enable it, it will not be OK. I reset watchdog only once at the initial state highlighted with bold character.
DualConfig0 : process( plClk )
begin
if rising_edge( plClk ) then
slavmm_rcv_read <= '0';
sl3avmm_rcv_address <= B"000";
slavmm_rcv_write <= '0';
sl32avmm_rcv_writedata <= X"00000000";
case stDualConfigState is
when ST_DUALCONFIG_IDLE =>
if slGoReboot = '1' then
if slToBeErase = '0' then
stDualConfigState <= ST_DUALCONFIG_WRWAIT;
slavmm_rcv_write <= '1';
