Guest pedro_trying_papilio Posted December 15, 2011 Report Share Posted December 15, 2011 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. Regards Pedro Link to comment Share on other sites More sharing options...
Guest pedro_trying_papilio Posted December 15, 2011 Report Share Posted December 15, 2011 Nevermind i was missing the fact that I need to use the picoblaze core!! ;D Link to comment Share on other sites More sharing options...
Jack Gassett Posted December 15, 2011 Report Share Posted December 15, 2011 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. Jack. Link to comment Share on other sites More sharing options...
