Hi expert,
I failed to use 16550 Compatible Uart to send data. Serial signal never change.
I have write the configure to the register:
0x4 to 0x0;
0xC to 0x80;
0x0 to 0x36;
0x4 to 0x0;
0xC to 0x03;
0x8 to 0xC7;
And then read 0x14, it returns 0x60:
And then write data to 0x0:
But sout and sout_oe never change. And then polling 0x14 always returns 0x0.
BTW, I have test this core with same configuration in simulation, it worked well.
Can you help that?

Based on what I can see in first picture, the address configuration are all 000h. Could that be the reason.
