Hi,
we're planning to design a custom AM335x based board running Linux. Because we need to use the GPMC, we cannot use MMC1 for connecting the eMMC containing the linux-os. So we plan to connect this eMMC to MMC0. But TRM Chapter 26.1.7.5.2 says, booting an eMMC-device from MMC1 is only supported for devices < 4GB.
That's why we plan to boot u-boot from SPI-NOR-flash and let u-boot doing the linux-boot from eMMC-devices >= 4 GB connected to MMC0.
Is this a possible way to overcome this limitation mentioned in TRM?
