The Amanero is connected with an external 3.3V psu, but there is no sound. I am sure that the connections are ok.

I guess that this is due to the fact that the display is not connected. It must be necessary to use the input selector of the display. Can anyone confirm please?


There are two output 5V pins in J9. Are they there for a specific reason?

So, you are connecting an Amanero to the second i2s port in order to compare it to the onboard xmos, right?

What firmware version is your board? The early firmware release did not enable the i2s port and you will need to update. The display has likely nothing to do with it as the default setting of the board is for automatic scanning of the inputs. Unless you have changed this the active input should be automatically selected.

Yes.

I bought this board may be 6 weeks ago. I understant that the active input should be automatically selected. How can I update it, if it is what I should do?

Check the firmware version and update if not the latest. The procedure of updating via a terminal program and a serial port is described in the manual.

Ok, I will read it carefully and try to it myself. If I can't do it, I have a friend who can. Thanks!

hello, is there a 1941 board owner willingly to make some tests and post them on forum?


dam1121 fpga changes the frequency of si5xx to keep fifo functional once per 1ms.

I'm curious to know if dam1941 will make the same when useing the xmos input. Theroretically if fpga and xmos run sync, those changes in frequency would't be necessary, but who knows?


So, anybody having 1941, a cheap logic analizer to log the i2c and some time? I will give the beer!

For DAM boards with on-board USB, no clock adjustments Sören says.
