I need to try and narrow down if this is a board problem or some other setup problem.

On boot I get a continuous error;
mmc0: Error 110 whilst initialising SD card and Problem reading SD status register.

After a period of time, up to 5 minutes it boots.

HDPARM -t shows 1.16MB/sec which is ridiculously slow (10.43MB/sec) on my HP laptop.

A Sandisk Extreme Class 10 will not boot at all continuously giving error;
mmc0: timeout waiting for hardware interrupt.

Using a 1AMP PSU.

Sounds like an SD card issue to me. Are you using the debian wheezy beta? It works with a wider selection of SD cards than the Squeeze version.

Read the wiki first, all your topics are discussed there, and in other forumtopics, like this one:

Thanks Mahjongg, that sorted my unbranded (Supposedly Toshiba) SD card but strangely not my Sandisk Extreme.

Tried Wheezy on the Sandisk but I get nothing after the Raspberry image comes up on the screen.

Perhaps the "SanDisk extreme" is a cheap chinese copy, a "fake". Its especially the SanDisk Extreme brand that is copied, and a large part of SanDisk Extremes you buy on ebay are fakes!

Just google for "SanDisk fake" and you will see what I mean.

The biggest problem (except very low quality and speed) is that "2 GB" fake cards often actually are only capable of storing 1 GB.

.

I think I am OK with the sandisk, bought from a reputable outlet (Not ebay) and it shows as 16GB.

There is a recent discovered issue with pullups not enabled on some of the SD-card control and data lines, which can be solved in software, but might not yet have been in the software you have been using.

Yes download bootcode.bin from here:
https://github.com/raspberrypi/firmware ... aster/boot
and replace the one on your sdcard.

OK, done that, will check it out tomorrow.

Thanks,
