I tried with a 32GB Sandisk high endurance SD and a 64GB Sandisk
Ultra SDXC UHS-I and both worked.
Can you tell me which 64GB sd cards you tried booting with? And also,
which steps you followed to get the errors (which image to download,
etc...)?
thanks
Gilles.

I flashed the image freshly, to another SD card, and it boots happily. So I can confirm your patch works. :-) I don't know what's wrong with the partition table on the original SD card. I manipulated with the partitions and their properties a bit before but parted or the other versions of U-Boot I tried don't report any problem. Maybe the U-Boot version from master that I happened to compile does something differently. Anyway, it's unlikely to be related to this patch as it boots fine on a freshly flashed SD card. Thank you for the patch, hopefully it'll get merged. Regards, Milan
