Hello all.
I am a newbie and I am trying to run a linux on hps for DE1_SOC. I am using Quartus 18.1 and soc eds 18.1 on windows.
First of all I download a linux console zip file form terasic website and burned the image into sd card using win32diskimager software.
After that I had created a custom system platform designer ( picture is attached here)
and programed board using quartus programmer.
Then using bsp-editor tool I create a preloader file from hpsfpa handoff files and used the command “alt-boot-disk-util -p preloader-mkpimage.bin -a write -d D” to load the preloader file into sd card.
When I put sd card into de1 soc board run putty terminal, it is giving error of “reading uboot.scr file”.
How should I create a uboot file, what about the device tree files and how should I tell it to run linux yocto that I had download from teraisc.
I had tried follow the rocketboards workshop on the same topic but they are using some different Qsys system and pre designed files, which I couldn’t map to my custom design.
Any help would be appreciated. ( please keep in mind that I am a newbie and might not understand easily the things that might seems trivial to you).
Thanks in advance.

Actually I have followed the document from here. The document is also attached here below. ( starts at page 68 ).
Basically What I did is
=> created a preloader image file using bsp-editor
=> build u-boot from git://git.denx.de/u-boot.git (before building I changed the content of file "/u-boot/include/configs/socfpga_cyclone5_socdk.h"
changed #define CONFIG_BOOTCOMMAND value to "run callscript"
and replaced #define CONFIG_EXTRA_ENV_SETTINGS value to
"scriptfile=u-boot.scr" "\0" \
"fpgadata=0x2000000" "\0" \
"callscript=fatload mmc 0:1 $fpgadata $scriptfile;" \
"source $fpgadata" "\0"
It was written in the document ( page 71 ) that it was done to make sure that our custom boot script will run after preloader.
The u-boot.script file is also attacehd here for the reference. starting few lines are ################################################################################
echo --- Resetting Env variables ---
# reset environment variables to default
env default -a
echo --- Setting Env variables ---
# Set the kernel image
setenv bootimage zImage;
but as seen in the logs on putty snapshot below this script is not being executed and some other error occurred. Could you kindly look into it.
