yes, sorry, my local mirror. I will fix that.

Of course, one would need a seperate configuration file. I'm using "zynq_fsbl_defconfig" for the small one and "zynq_defconfig" for the bigger one for my own tests.
I'm currently booting from SDcard and i have not realised any problems with the FAT support so far. But with the arasan-sdhci driver when writing, see my patch below which fixes it for me but I haven't dived into the drivers very deeply yet.

best regards
