Hello, We want to build boot image for customized cyclone V SoC board.We are following the below document, using Quartus Prime 22.1 Standard Edition on Ubuntu 20.04 system,https://www.rocketboards.org/foswiki/Documentation/BuildingBootloaderCycloneVAndArria10#Appendix_45_Building_Linux_Binaries We are getting below error while building uboot/usr/bin/ld: tools/imagetool.o: in function `imagetool_get_type':imagetool.c:(.text+0xa): undefined reference to `__stop_image_type'/usr/bin/ld: imagetool.c:(.text+0x12): undefined reference to `__start_image_type'/usr/bin/ld: tools/imagetool.o: in function `imagetool_verify_print_header':imagetool.c:(.text+0x73): undefined reference to `__stop_image_type'/usr/bin/ld: imagetool.c:(.text+0x7a): undefined reference to `__start_image_type'collect2: error: ld returned 1 exit statusmake[1]: *** [scripts/Makefile.host:104: tools/dumpimage] Error 1make: *** [Makefile:1900: tools] Error 2 Can you please share your insights.

Hi SnehalJust to update the forum case.The missing steps from the RBO page are the steps below:1.Step to convert the sof to rbf. You could use the command below to convert the sof.quartus_cpf -c -o bitstream_compression=on soc_system.sof soc_system.rbf2.Missing u-boot.scr could be gotten from the gsrd page. https://releases.rocketboards.org/2025.03/gsrd/c5_gsrd/u-boot.scr3.Place both rbf and the u-boot.scr in the sdcard partition 1 (sdfs)RegardsJingyang, Teh

Hi

Sorry for the late reply.

If you are using the latest in the repo, there might be some bugs that was recently uploaded.
In the uboot repository, could checkout the branch "git checkout -b test-bootloader -t origin/socfpga_v2024.04" .

I think there is a missing parameter, try adding this before or after step 6:
export ARCH=arm

Hi

I tried the steps and able to build uboot successfully.

Could you try setting :
export CROSS_COMPILE=arm-none-linux-gnueabihf-

Also check the path for the compiler to be set properly:
wget https://developer.arm.com/-/media/Files/downloads/gnu/11.2-2022.02/binrel/gcc-arm-11.2-2022.02-x86_64-arm-none-linux-gnueabihf.tar.xz
tar xf gcc-arm-11.2-2022.02-x86_64-arm-none-linux-gnueabihf.tar.xz
rm gcc-arm-11.2-2022.02-x86_64-arm-none-linux-gnueabihf.tar.xz

Further more the cv_bsp_generator.pt needs to run using python2 instead of python3
export PATH=`pwd`/gcc-arm-11.2-2022.02-x86_64-arm-none-linux-gnueabihf/bin:$PATH

Hi

Could you try installing some pre-requisite packages below:

sudo apt-get install gawk wget git-core diffstat unzip texinfo \
gcc-multilib build-essential chrpath socat cpio python python3 \
python3-pip python3-pexpect xz-utils debianutils iputils-ping \
python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev pylint3 xterm \
libncurses-dev gawk flex bison openssl libssl-dev

If not could you try building it in Ubuntu 22.04 with the packages above too.

Hi

The ddr in the hardware you are using is having a 512MB DDR as where the GSRD for the devkit is having 1GB.
Please change the device tree arch/arm/dts/socfpga_cyclone5_socdk.dts to

memory {
name = "memory";
device_type = "memory";
reg = <0x0 0x20000000>; /* 1GB */
};

Hi

The changes looks good in the device tree.
What is the new error message that you are getting?
Did the logs show the DDR size define in the device tree size to be 512MB?

  Hello,
  1) PFA debug log images,
  Image_1 is when baud in 115200 uboot boot log is visible but as soon as it goes to kernel config then it shows garbage data,
  if baud changed to 230400 then uboot boot log is not visible garbage data but kernel boot log can be seen after that all system runs on 230400 baud even able to run the application.
  2) PFA debug log, we have enabled emac 0 hps peripheral in fpga mode. But ethernet is not being detected. Is it because we are using dtb file generated by the steps mentioned in the below document. Do we need to generate dtb by some other steps, if yes please share the steps.

  Hello,
  Can you help with command to generate dts with sopcinfo and board xml files as input.
  The below command works in SOC EDS, which is discontinued in Quartus 22.1
  sopc2dts --input soc_system.sopcinfo\
  --output soc_system.dts\
  --type dts\
  --board soc_system_board_info.xml\
  --board hps_common_board_info.xml\

Hi

The sopc2dts tool have been discontinued.
Currently, all device tree example are created and stored in the uboot branch and linux branch (arch/arm/dts/socfpga_cyclone5_socdk.dts).
It is advisable to make changes to the devkit device tree.

Are you using 2 different UART baudrate for the linux and uboot?
Can you share me both linux and ubiit device tree to me?

  Hello,
  1) Are you using 2 different UART baudrate for the linux and uboot?
  -- during built can we select baudrate, PFA uboot and device tree
  
  2) Following the steps https://www.rocketboards.org/foswiki/Documentation/HOWTOCreateADevicetreeForCycloneVSoC, we could generate a dts file for customized board but facing issue while generating a dtb file. Below is the error message
  
  DTC arch/arm/boot/dts/my_cv_fpga_overlay.dtb
  Error: arch/arm/boot/dts/my_cv_fpga_overlay.dts:50.10-11 syntax error

  make: *** [Makefile:1403: my_cv_fpga_overlay.dtb] Error 2
  
  PFA header and dts file generated, as per our observation dts is not being updated wrt to header file generated..
  Can you please share the pointers.

Hi

In the new flow the sopc2dts generator have been discontinued and should no be used.

You will have to make the changes base on the devkit device tree located in the location :
https://github.com/altera-fpga/u-boot-socfpga/blob/c13fb267004c4c79d3573360f033f4a32e8a3c79/arch/arm/dts/socfpga_cyclone5_socdk.dts#L4
