UART example 1.0

[Guest pedro_trying_papilio]

So i was trying to reuse/modify the uart example available on the file repository, so as to allow me to stream to a computer some data being computed by the fpga.

(using  XST version .12.4)

When i tried "translate" it gave the following error:

ERROR:NgdBuild:604 - logical block 'INST_UART_TX' with type 'uart_tx' could not

  be resolved. A pin name misspelling can cause this, a missing edif or ngc

  file, case mismatch between the block name and the edif or ngc file name, or

  the misspelling of a type name. Symbol 'uart_tx' is not supported in target

  'spartan3e'.

ERROR:NgdBuild:604 - logical block 'INST_UART_RX' with type 'uart_rx' could not

  be resolved. A pin name misspelling can cause this, a missing edif or ngc

  file, case mismatch between the block name and the edif or ngc file name, or

  the misspelling of a type name. Symbol 'uart_rx' is not supported in target

  'spartan3e'.

Now first thought was I messed up when feeding serial_out with bit by bit streamed 8bit message. But when I used the original unmodified example I got the same error. obviously the example is provided just as starting point template but I am not really sure how to go around this?

My only experience is in simulations with modelsim so anything past "check syntax" is uncharted waters for me.

Nevermind i was missing the fact that I need to use the picoblaze core!!

;D

Yes.

Due to the license agreement that the uart and picoblaze code is released under I was not able to provide it with the package.
