Hello, I'm new here, so I'll introduce myself, I'm an embedded software developer working with ARM based boards (A10, iMx, AM335x) from the Netherlands.
I've been working on a custom linux installation for the BBB (buildroot). There's only one nagging problem I can't seem to solve. For booting I use u-boot and an uSD card with three partitions. The first is FAT. This work fine. But then comes the problem: eMMC. It seems like the only way to let the BBB boot off the eMMC is to create a FAT partition (#1) that goes from cylinder 1 to 9 (255 heads, 63 sectors). The eMMC is big enough for sure, so that's no problem, but it bothers me that I can't seem to change the partition size, and I don't understand why. On the partition is a vfat filesystem with the MLO, u-boot.img and uEnv.txt files. I've read the AM335x technical reference thoroughly, checked all the boot flowcharts against a hexdump of the mmcblk1 device, but I can't find the reason why the device won't boot when I change the partition size. Does anyone know about any requirements I've missed? Is the size a given constraint? I would like to use a very small FAT partition of 1MB or so..
