hi all,

i made a very small design and i got some problem with the jtag uart terminal output. i compiled a simple "hello world" and everything works fine excepted that jtag uart is "dyslexic" : instead of "hello world" i get "hhello world" in the jtag uart console.

anybody can help ?

Well, I found the solution, but I don&#39;t know why it works ... http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/mad.gif

Originally my master clock was 12 MHz, including JTAG UART. Then I changed only the JTAG UART input clock to 50 MHz... and it works . Strange. Is there something hard coded into JTAG UART which need a clock faster than 12 MHz ?
