I'm just building a kernel with PRINTF_BUFR_SIZE=128 is this the recommended
value? I'll see if that fixes it but what I've seen is a mixture of what
looks like jumbled chars and total Greek i.e. none a-zA-Z0-9... chars.
I'll look to get a screen shot of the console if I can reproduce reliably.
Thanks for the quick answers :)
Regards
Steve
