[J-core] Weird console output

[Daniel Lezcano]

Hi all,

I am very new to this project and almost everything related to CPU 
design. I am just a kernel developer.

I followed step by step the tutorial.

  - using ttp://j-core.org/downloads/binaries/mimas_v2.bin
  - checked sha1sum dcc14d4c7ed1fd36618b2704a6b73d43d82bd18b
  - not sdcard + vmlinux yet just waiting for "CPU tests passed"

Unfortunately the console output is showing:

CUtt psdGBtb oH20H RMrviio:0262c2f358
                                      i:M ug105: DT25Bon

etc ...

Different operations:
- console 115200 8N1 (flow control off sw/hw)
- tried different console speed rate in case but without success
- tried minicom, stty, screen with the same result

It looks like the console is missing some characters or something like that.

I tried an uart_output test found on the numato web site [1] and it 
seems the uart is correctly working.

Any ideas how to fix this ?

Thanks in advance.
