Re: USB Device Overwrites SD Card (permanently)

I sent the card along with one of the pis to an old engineering co-worker that has much more experience with hardware than I. I'll update the thread once he has some additional information. I read all the relevant information on parted and fdisk and was able to confirm that block device itself is lo...

Re: USB Device Overwrites SD Card (permanently)

I tried all the n00b stuff :) It's definitely not the SD card lock. I don't even think the pi would boot with a read only root partition. I would test this now, but all my SD cards have an un-deleteable CDFs partition. I was able to reproduce this behavior 3 times (and would be willing to send the c...

USB Device Overwrites SD Card (permanently)

I have a sophisticated setup that uses two rpis that work in conjunction to provide GPS and 3G services. The 3G modem I use is a Huawei e220 which happens to have a small amount of on-board memory that contains drivers for various operating systems. Since the partition is formatted as CDFs; linux re...

Re: Mono / C# and the Framebuffer

You might want to have a look at svgalib and/or libggi if you are absolutely sure you can't get used to SDL. Neither of which have wrappers for c# that I am aware of, meaning you'll have to make all your calls through [DLLImport]. Though I think you'll find that SDL is a dream compared to other grap...

Re: Mono (C#) anyone?

I've been using Mono exclusively to write a data acquisition service that connects to a USB GPS adapter as well as a USB 3G modem (both of which are standard serial devices) and collects, sends, and receives commands remotely. Not counting USB current issues, it has worked perfectly. Connecting to a...
