Why does u-boot hang on Intel® Arria® 10 SoC devices when I use External FPGA Configuration with no external memory? - Why does u-boot hang on Intel® Arria® 10 SoC devices when I use External FPGA Configuration with no external memory? Description Due to a problem in the SoC EDS software version 16.0 and later, u-boot-socfpga might fail to boot for Intel® Arria® 10 SoC designs when: External FPGA Configuration is selected in BSP-Editor / u-boot-socfpga There is no External Memory Interface (EMIF) connected to the HPS Resolution To work around this problem, in u-boot-socfpga boot loaders generated from the SoC EDS software version 16.0, download and apply the u-boot-socfpga_arria10_sdram.patch . The patch makes changes to uboot-socfpga/arch/arm/cpu/armv7/socfpga_arria10/sdram.c , adding a #define for the non-existence of an external memory interface. To apply the patch, follow these steps: Copy the .patch file to the uboot-socfpga directory created when make was run from your bsp-editor generated BSP (software/<bsp name>/uboot-socfpga) git apply <filename>.patch Move to the bsp directory: cd .. Rebuild u-boot: make clean; make. Write the updated uboot_w_dtb-mkpimage.bin to your sdcard / QSPI. This problem is scheduled to be fixed in a future release of the SoC EDS software.
