Question Secure Digital (SD) Memory Driver Problems?


I recently bought Sharp's new developer
edition Lunux based PDA (5000D). It has a SD
slot so I bought a 64MB ScanDisk card.
Unfortunately everytime I try to copy files
over a couple of MBs the I/O operation fails
with an error.

I was just wondering whether there are known
issues with the SD device driver, or whether I
just have a duff card which I should change?

Regards

Steve

I couldn't find anything -- hardly a surprise seeing as how new it is. You do know that Sharp has its own forum for this beast?

Other than that, what do you think of it? I was considering it myself, but I opted to get the iPAQ instead (a 3835).

Thumbs up

Yes, I do know that Sharp have their own boards
for it and don't worry I lurk there a lot. I have
reported my problem with the SD card and I they
are looking into the fault but couldn't tell me
whether it's a Linux kernel bug or my card. I
have myself searched the net for reported linux
driver faults, but sd isn't a good search term
in 'linux space'.

Sharp have recently posted the linux kernel source
but interestingly have excluded the SD memory
driver for 'commercial licensing' reasons. Therefore, even if I was up to it (and my confidence probably isn't up to this challenge - it gets dented with age - 'oh the arrogence of my youth') I couldn't fix it myself.

With respect to your question on the device. I
like it. The main reason for me buying it was to experiment with Java on a PDA. However, the start-up time for Jeode on this device is probably too slow to be practical for non Java enthusiasts. Perl & python have also been made available.

The ability to edit source code with vi (or micro emacs if that's to your taste) and then compile
Java code on the device using jikes is pretty cool, but most developers will probably develop using their favorate IDE on a PC and then download packaged software. The ipk distrbution files are easy to create using tar & gzip and appear to be effective.

I'm particulraly looking forward to the Hancom office embedded product which would further improve it and make it more usable for my work.

I believe that the bulk of the general pupose applications for the Sharp will probably be written in C++ using the QT environment.

Regards

Steve
