Re: [casper] ROACH2 U-boot failure / USB failure

[Tony Goodson]

Thanks Alec,

That worked!  I'm used to always having a minicom terminal up at start.
When I didn't, it successfully reloaded u-boot.  We're up and running now.

Really appreciate the help!

Hi Tony, the initial u-boot is transferred using x-modem. This is done via
serial link. If you have a minicom session open there will be a com port
clash. Try again with minicom closed.

Regards
Alec

PS. I'll go take a look at the code and see what else could be wrong but I
think it's just a com port clash.
