- Finally, I proceed with the creation of the SDcard image, and here the problems begin. I started with the paragraph “Creating SD Card Image Using Provided Script”. The guide, as I read, presents details on how to create the gsrd bootable sd card image, similar with the sd card image that is provided as part of the precompiled binaries package. The tool used is make_sdimage.py.
Of the files required, I cannot find the one indicated as “u-boot-arria5.img: U-boot image, Compiled by Yocto with bitbake virtual/bootloader” and the problem is probably related to the recompilation of the kernel.
Now the guide offers two possibilities:
1. Creating SD Card Image Using Prebuilt Binaries: this section presents how to use the script to create the Cyclone V SD Card by using the prebuilt binaries.
In this case the instructions I run are:
Download the binaries into the home folder and extract them, and cd to the binaries folder:
cd ~
mkdir linux-socfpga-gsrd-17.1-cv-bin
# 17.1
wget
https://releases.rocketboards.org/release/2017.10/gsrd/bin/linux-socfpga-gsrd-17.1std-cv.tar.gz tar -xvzf linux-socfpga-gsrd-17.1std-cv.tar.gz -C linux-socfpga-gsrd-17.1-cv-bin
Download the script and the webserver contents archive into the current folder:
cd ~
# 17.1
wget
http://releases.rocketboards.org/release/2017.10/gsrd/tools/make_sdimage.py chmod +x ~/make_sdimage.py
Create the root filesystem to be put on the SD card image:
cd ~/linux-socfpga-gsrd-17.1-cv-bin
mkdir rootfs
xz -d gsrd-console-image-cyclone5.tar.xz
sudo tar xf gsrd-console-image-cyclone5.tar -C rootfs
Copy u-boot.scr in the working folder
cd ~
cp u-boot.scr ~/linux-socfpga-gsrd-17.1-cv-bin
Call the make_sdimage.py script:
cd ~/linux-socfpga-gsrd-17.1-cv-bin
sudo ~/make_sdimage.py
-f
-P preloader-mkpimage.bin,u-boot-cyclone5.img,num=3,format=raw,size=10M,type=A2
-P rootfs/*,num=2,format=ext3,size=1500M
-P zImage,u-boot.scr,soc_system.rbf,socfpga.dtb,num=1,format=vfat,size=500M
-s 2G
-n sd_card_image_cyclone5.bin
Now, the image is created, but when I run it on the Devkit, it gets stuck with the following

And I cannot explain what happens: probably there is no correspondence from what is described in the device tree and what the kernel expects.
