SD card as a storage in pocket beagle

> Can I use an sd card in pocket beagle to store images coming from the camera

Yes, the PocketBeagle has an SDCard connector on the mainboard

> over a gigabit interface

The PocketBeagle does not come with a gigabit interface. I'm not sure you could wire one up, it'd require some hackery.

> or USB

Yes you could use USB for a camera

It should be able to boot from USB however there's nothing stopping you from booting from SDCard and saving images to SDCard, you'd need additional electronics to have it boot from an Ethernet network (as it'd have to support PXE)

Thanks, Christopher for your reply. What is the maximum size of sd card I can interface with pocket beagle and is it possible to interface multiple sd card?

SDCards typically communicate via SPI protocol, so to use more than one you'd have to find a way to interface another SDCard, either via a USB reader or if another SPI interface is broken out on the pins via pinmuxing (check the PocketBeagle GPIO Pinout , there is SPI0 and I2C on there)

As for the maximum size, I believe you're restricted to whatever filesystem you use on it, remembering that you're on a 32bit processor and likely linux. As far as I'm aware there's no particular limit.

But as per my knowledge it depends on sd card or eMMC version it support. Can you please again take a look on it?

I don't know what you mean.

I want to say, the size of the sd card I can interface depends on the sd card version of our processor support instead of the filesystem we're using. So can you please confirm it with your source ?

> depends on the sd card version of our processor support

I'm not sure what this means, I have not heard of such a thing.

I think it depends on what sd card reading device you use. If you want to read an SDXC card ( 64 gb or larger) the sdxc interface uses lower voltages. The sd slot on the pocket beagle may be limited to sdhc cards.  So that may limit you, I’m not sure, I haven’t tried it.  But I assume that if you have a usb-sdxc card reader inserted in a usb port, linux would recognize it.

Thanks, Allen. I think I should give try this also. But still, the question is unanswered, what capacity of microsd card can get interface directly.
