Cyclone V DE10-NANO: Not able to boot to Linux kernel using u-boot.scr

Boot

Hi everyone.

I am following this guide to build the bootloader and Linux kernel.

Then I change the following files in order to load the u-boot.scr:
u-boot-socfpga/include/configs/socfpga_common.h

#ifndef CONFIG_EXTRA_ENV_SETTINGS
#define CONFIG_EXTRA_ENV_SETTINGS
“fdtfile=” CONFIG_DEFAULT_FDT_FILE “\0”
“bootm_size=0xa000000\0”
“kernel_addr_r=”__stringify(CONFIG_SYS_LOAD_ADDR)“\0”
“fdt_addr_r=0x02000000\0”
“scriptaddr=0x02100000\0”
“pxefile_addr_r=0x02200000\0”
“ramdisk_addr_r=0x02300000\0”
“socfpga_legacy_reset_compat=1\0”
“scriptfile=u-boot.scr” “\0”
“fpgadata=0x2000000” “\0”
“callscript=fatload mmc 0:1 $fpgadata $scriptfile;”
“source $fpgadata” “\0”
BOOTENV

u-boot-socfpga/include/config_distro_bootcmd.h

#define CONFIG_BOOTCOMMAND “run callscript”

And my u-boot.scr

echo – Programming FPGA –

fatload mmc 0:1 $fpgadata soc_system.rbf;
fpga load 0 $fpgadata $filesize;

#enable HPS-FPGA, FPGA-HPS bridge
bridge enable;

#set up env variable
setenv fdtimage soc_system.dtb;
setenv bootimage zImage;

setenv mmcroot /dev/mmcblk0p2;
setenv bootargs console=ttyS0,115200 root=${mmcroot} rw rootwait;

echo --1–
mmc rescan;
fatload mmc 0:1 ${loadaddr} ${bootimage};
echo --2–
fatload mmc 0:1 ${fdt_addr_r} ${fdtimage};
echo --3–
bootz ${loadaddr} - ${fdtaddr};

but it cannot boot to Linux kernel

Hey
I had same issues.
I think your FPGA config cmd is wrong.
Try this guide: https://github.com/robseb/HPS2FPGAmapping#2-part-building-of-the-primary-bootloader-with-intel-eds
That should help.

Thanks robseb

I could load the rbf file and linux with no problem using EDS 18.1, but if I do it at EDS 20.1, I get this error.

Thanks

I’m not an expert, but perhaps the version of the kernel you are using is an older one? Maybe you can try compiling a newer version of the kernel (Ex: 5.8)? The steps are explained in the appendix of the same link you shared.

EDIT: I have a kernel compiled already if you want to try with it, download it here. Tested it and it works on my DE10-Nano.
