Inserting Card causes reset

[tz1]

It might just be a power surge when the card first comes on, but every time I insert a card, it resets the OpenLog (it also happens with others - jpeg trigger, for example). I don't think it happened with my arduino to breakout setup.

This is probably not a problem, however I was thinking about dual drives (save to B when A is full, and allowing swapping A).

This is sort of a known issue but falls outside the realm of normal use. We won't be supporting hot swapping at this time.

It's actually convenient when the DTR wiggle isn't working.

Oh hey TZ - I was reading your blog. Please note that the default avrdude doesn't toggle DTR at all. To get the reset trick to work, Arduino had to compile their own version of avrdude. So if you're trying to serial bootload (using DTR to reset a device and kick off the bootloader), make sure you're using the avrdude that ships with Arduino.

Thanks for the tip - Acutally the environment (-0017) still doesn't work for me.

I think it is a linux thing. I'm using a patched version of avrdude that has the arduino as a discrete selection (and a fix for the AVR Dragon), but the FTDI driver also has some recent changes, though libusb will work to toggle the line. So it might take a few more versions before arduino, linux, and ftdi all work together.
