Linux not Booting on custom Intel Cyclone V board

Hi. Thanks for the reply. I am implementing the solution and will update the progress and result within 2 days.

Hi.

I followed the solution step by step with Quartus 20.1.

I got an error while executing "arm-eabi-objcopy -O binary application.elf application.bin". So I executed "arm-eabi-objcopy -O binary application.axf application.bin" instead as there was an axf file present. Finally, I was able to generate application.bin and application.img.

QSPI part did not work and threw "cat: qspi-image.bin: No such file or directory".

Now I have u-boot.img, application.img and soc_system.rbf. Should I put these files on the sdcard as (Embedded Linux Beginners Guide | Documentation | RocketBoards.org) had suggested? Then, u-boot.scr still needs to generated.

Your earlier solution suggested using "gcc-arm-11.2-2022.02-x86_64-aarch64-none-linux-gnu" with bitbake which is a different way. In case, you are following any approach, please elaborate.

Hi,

I burned your image on the sd card and tried booting up but it also resulted the blank screen as before.

I have 2 boards and tried the image on both boards so hardware fault is less likely. Since the guide we are following does not dictate the precise pin and jumper configuration for SoCkit, I request you to check for the pin configuration.

Thanks,

Akash.

Hi, Thanks. I am happy that you replied early. Please help and determine the method for custom boards as per currently available gits and toolchains.

Hi,

I downloaded the "gcc-arm-11.2-2022.02-x86_64-aarch64-none-linux-gnu" and declared "export ARCH=arm64" as you suggested but EmbeddedLinuxBeginnerSGuide failed at step 4 (Generating the Preloader) when I entered the make command. It asked to set ARCH=arm, after which it compiled successfully.

Then I cloned "u-boot-socfpga" and checked out rel_socfpga_v2023.01_23.09.02_pr branch. I followed the guide further till step 5 (Configure and Compile U-Boot) and it failed at "make" command. The output is as follows:

Hi, I opened "https://supporttickets.intel.com" for this ticket and posted my reply there. Do I need to do something else to reopen this post?

Hi Aliff.

Thanks for the reply, I was able to generate qspi-image.bin.

Your suggested method seems to be inspired from Building Bootloader Cyclone V.

If it is the case, setting "ARCH=arm64" and "CROSS_COMPILE=aarch64-none-linux-gnu-" does not result positively. Were you able to implement the method suggest in this guide successfully? What device did you use to implement the method?

Thanks,

Akash.

Hi,

I followed Building Bootloader CycloneV line by line and was able to generate the sdcard_cv.img without any error but it gives a blank screen on SoCkit i.e. u-boot doesn't boots up. I got a reference from cyclonev-programming-fpga-from-u-boot here and downloaded a prepared sdcard image which jackfrye11 has posted on google drive.

Replacing his u-boot-with-spl.sfp with mine made my sdcard work. This determines that I have a problem in generating the u-boot-with-spl.sfp for sure. Since the guide used a GHRD zip to generate everything using nios_embedded_shell.sh and generate_from_tcl for their dev board, I don't get to see the complete project. What I generated using their commands was targeting to their dev board. How to approach this step (where make generate_from_tcl and make sof were executed) when using a custom board and design? Particularly this part below:

==============================================

cd $TOP_FOLDER
rm -rf ghrd-socfpga-QPDS22.1STD_REL_GSRD_PR QPDS22.1STD_REL_GSRD_PR.zip cv_soc_devkit_ghrd
wget https://github.com/altera-opensource/ghrd-socfpga/archive/refs/tags/QPDS22.1STD_REL_GSRD_PR.zip
unzip QPDS22.1STD_REL_GSRD_PR.zip
mv ghrd-socfpga-QPDS22.1STD_REL_GSRD_PR/cv_soc_devkit_ghrd .
rm -rf ghrd-socfpga-QPDS22.1STD_REL_GSRD_PR QPDS22.1STD_REL_GSRD_PR.zip
cd cv_soc_devkit_ghrd
rm -rf software
~/intelFPGA/22.1std/nios2eds/nios2_command_shell.sh \
make generate_from_tcl
~/intelFPGA/22.1std/nios2eds/nios2_command_shell.sh \
make sof

=================================================

Also, for EmbeddedLinuxBeginnerSGuide , there is a preloader-mkpimage file as a preloader in a2 partition. Its u-boot.img was generated using "intelFPGA/18.1/embedded/host_tools/altera/preloader/uboot-socfpga.tar.gz" which is a 2013 version. This u-boot causes fatload command issue for me and I could see other people struggling with same issue for months. Otherwise this method seemed to have a better control over things.

Overall both the methods fail for me due to u-boot.

Thanks for your responses and support.

Akash.
