Cyclone V SoC Devkit problems compiling Angstrom kernel

2. Creating SD Card Image Using Rebuilt Binaries: in this case the guide is very laconic, as it explains that: this section presents how to build the sd card image for arria v from the rebuilt binaries. this is very similar with creating using prebuilt binaries, except using the files from where they are built. the default locations are used.

This is followed by the list of locations.

Now, I try to recover the files required by the list following the locations shown; Obviously, lacking the file u-boot-cyclone5.img, I have tried to rename the file u-boot.img that I have found in the folder created after the kernel compilation. So, I have written the following set of instructions:

cd ~

mkdir linux-socfpga-gsrd-17.1-cv-bin

cd ~/linux-socfpga-gsrd-17.1-cv-bin

mkdir rootfs

cp /home/davide/angstrom-build/deploy/glibc/images/cyclone5/gsrd-console-image-cyclone5.tar.xz /home/davide/linux-socfpga-gsrd-17.1-cv-bin

xz -d gsrd-console-image-cyclone5.tar.xz

sudo tar xf gsrd-console-image-cyclone5.tar -C rootfs

cp /home/davide/angstrom-build/deploy/glibc/images/cyclone5/zImage /home/davide/linux-socfpga-gsrd-17.1-cv-bin

cp /home/davide/SDcard/u-boot-cyclone5.img /home/davide/linux-socfpga-gsrd-17.1-cv-bin# cd /home/davide/angstrom-build/deploy/glibc/images/cyclone5# mkdir prova# cp /home/davide/angstrom-build/deploy/glibc/images/cyclone5/gsrd-console-image-cyclone5.tar.gz /home/davide/angstrom-build/deploy/glibc/images/cyclone5/prova# cd /home/davide/angstrom-build/deploy/glibc/images/cyclone5/prova# gunzip gsrd-console-image-cyclone5.tar.gz# cp /home/davide/angstrom-build/deploy/glibc/images/cyclone5/prova/gsrd-console-image-cyclone5.tar /home/davide/linux-socfpga-gsrd-17.1-cv-bin

cp /home/davide/cv_soc_devkit_ghrd/soc_system.rbf /home/davide/linux-socfpga-gsrd-17.1-cv-bin

cp /home/davide/cv_soc_devkit_ghrd/software/spl_bsp/preloader-mkpimage.bin /home/davide/linux-socfpga-gsrd-17.1-cv-bin

cp /home/davide/cv_soc_devkit_ghrd/socfpga.dtb /home/davide/linux-socfpga-gsrd-17.1-cv-bin

cp /home/davide/u-boot.scr /home/davide/linux-socfpga-gsrd-17.1-cv-bin

cp /home/davide/u-boot-socfpga/u-boot.img /home/davide/linux-socfpga-gsrd-17.1-cv-bin

cd /home/davide/linux-socfpga-gsrd-17.1-cv-bin

mv u-boot.img u-boot-cyclone5.img

Now, writing again the image created on the SD card, the DevKit again gets stuck (with no surprise). The output is:

• NOTE: since I work with Virtualbox, Ubuntu cannot see the SD card reader, so I transfer the image created to a shared folder with the host PC operating windows. Then I burn the SDcard with the Win32DiskImager program. When I use this program with the SDcard image delivered with the kit, it works fine, so I guess the problem doesn’t sits in this step.

Now, I follow for most of the procedure the guides on rocketboards.org, but I have the problems depicted. Something is surely wrong, but since I’m a newbie, I cannot discriminate where a mistake is made and/or which is the correct procedure.

My guess is that something goes wrong during compilation and something also during the SDcard image creation. Unluckily the guides are stingy od details and explanations of the steps, so it is difficult to me to understand what I am exactly doing.

Sorry for the length of the post, and also for my poor English. I hope I have given you as much detail as possible and that these details have been helpful in understanding my problem. If you need some clarifications, please ask, it is not a problem for me.

Best regards,

Davide Bombarda
