Hello,
I'm trying to understand what is necessary to get mainline U-Boot booting from the eMMC of an Arria10 board, which is significantly different to the Cyclone 5.
I'm playing with U-Boot v2019.10! I find some related documentation at [1]. Section "Arria 10 SoC - Boot from SD Card " seems to apply to the mainline U-Boot as well, at a first glance. Is there some similar doc for mainline U-Boot? What are the differences in mainline? Is it working or is something missing?
So I need at least three partitions on the eMMC:
1. VFAT partition with u-boot.img and fit_spl_fpga.itb 2. A2 partition with 4x u-boot-spl.sfp (or u-boot-with-spl.sfp) 3. Linux partition
Where do I specify the physical number of the partition 1.?
Is it still possible to load the secondary bootloader (u-boot.img) from offset 0x800 of the A2 partition? It seems that "SPL_FS_FAT" breaks it.
