Thanks for taking the time to help me.
I went ahead and made the changes you mention. Still no reaction from the MX.
I changed the two files so this:
module leds(output wire LED0,
output wire LED1,
output wire LED2,
output wire LED3);
assign LED0 = 1'b0;
assign LED1 = 1'b0;
assign LED2 = 1'b0;
assign LED3 = 1'b0;
endmodule
And for the leds.pcf:
set_io LED3 52
set_io LED2 55
set_io LED1 56
set_io LED0 49
No reaction after rebuild and upload.
I also cannot update the firmware using the instructions here: https://lawrie.github.io/blackicemxbook/GettingStarted/GettingStarted.html
I get this DFU-util error:
