Suggestion for Documentation additions

Fri Jul 25, 2014 4:06 pm

I'm trying to help a friend get his CM working but have spotted a gap in the documentation

After he's typed:
pi@raspberrypi ~/tools/usbboot $ sudo ./rpiboot
he reports getting another prompt, I've told him:

After that you should get a message something like "looking for BCM2835"
and then when it finds the Compute module half a dozen lines ending to the effect of: .. your device is now a mass storage device you can see it with ... (The instructions don't list the messages and my memory is fallible!)

It's probably worth mentioning that anyone can contribute to the documentation. There's an edit button which does all the magic necessary to send a pull request.

With my English I wouldn't want to inflict it on you.

Another aspect worth documenting I think.
Once you have it working, if you run rpiboot again to turn it into a mass storage device won't cause anything already written to eMMC to be wiped. I know I'm not the only person to wonder that!

The thing is that the documentations is supposed to be clear and succinct. Putting in information just because people might be wondering about stuff, could just be distracting to the rest of us. For the curious, the source code is available to read ;)

To answer your question though, the program that makes it a mass storage device is only written to memory, so it doesn't touch anything on the sd card (until you do).
