CYCLONE V HPS Boot - SDRAM Size Check Failed

Question

Hi

I have an CYCLONE V FPGA design that was compiled using Quartus 20.1.1. The RBF is working since we had tested this independently using old Quartus 18.1 boot flow. Now we are trying to boot with new boot flow mentioned here. But after we generate the files, create the SD card image and power up the boot is failing with the following error. A similar error is documented by Intel for Arria 10 FPGA here. When we tired to apply the patch here to the uboot code it failed. This could be because ours is a Cyclone V design for which this patch doesn't apply. Please show a way forward.

Best Regards
Syam

Hello syam,Have you tried the following build flow?https://rocketboards.org/foswiki/Documentation/BuildingBootloaderCycloneVAndArria10#Cyclone_V_SoC_45_Boot_from_SD_CardA tag for uboot-socfpga is different as below.# git checkout -b test-bootloader -t origin/socfpga_v2021.10The tag of the sites you pointed out is below.git checkout -b test -t origin/socfpga_v2020.04Thanks
