Booting from SD

2 weeks before I didn't had any problems with the boot of an Petalinux image. I formatted the SD card and copied the image back, but now it's not working. Fat32 is sufficient? Are there any known problems with the size of an SD Card?
Is it possible to see if the board is booting?
Thanks for your help!

I'm personally using a 4GB micro SDHC grade 4 from Kingston formatted with 2 partition, Fat32 and 3Gb ext4, and it's working fine.
It will be useful to know what you can see on the serial output?

Thank you for your reply Emilie!
There is nothing in Putty, only a black screen, because it's not possible to connect the board before it's booting.
The LEDs change in the booting process?
Maybe I should try JTAG.

Solved!
I don't know why, but when I changed the Jumpers JP7/JP8 to 1.8 Volt everything worked fine.
Thank you.
