How to start and run a baremetal aplication without the debug

Update1:

I found the file :

1.5.2. Booting from SD/MMC – Custom Partition (intel.com)

but it needs to be updated.

According to :

Building Bootloader for Cyclone V and Arria 10 | Documentation | RocketBoards.org

I still need to use bsp - editor but all the options are useless.

So if I want to start the baremetal program by sd card, what settings do I need to do in u-boot?

Do you have any updated guide or just explain the u-boot settings so that baremetal program can be loaded while booting?

Update 2:

According to 1.5.2. Booting from SD/MMC – Custom Partition (intel.com)

I need to get:

1. preloader-mkimage.bin, is it made from u-boot-spl or other files? The bootloader guide on rocketboards said that u-boot-spl.sfp is the file needed to the image.

2. the baremetal axf file to bin file and finally to -mkimage.bin file, so what is the mkimage -a need to be set ? what is that parameter decided from?

3. If I want to put them to SD card then the spl image is in A2 disk and can baremetal bin be at FAT or A2? How to set the UBoot to let the spl point to this image?(by setting the payload? And which setting can do this on menuconfig: spl.boot.SDMMC_NEXT_BOOT_IMAGE = 0x40000 )

Hi,

Please allow some time to check internally if there any guide available on this.

I will update ASAP.

Hi,

Yes, preloader-mkimage.bin is generated from u-boot-spl file.

For .axf to .bin you can use mkimage utility or

In eclipse, the post-build steps (under Build Steps tab in the C/C++ Build Settings):

fromelf --bincombined ${ProjName}.axf --output=${ProjName}.bin

Please find below link to compile the SPL and preloader for baremetal application.

https://www.rocketboards.org/foswiki/Documentation/PreloaderUbootCustomization131

We also have AN709, where it is explain for booting from SD card-Custom partition & FAT partition.

Let me know if you have any query on this.

Hi,

We have tested the baremetal application booting from QSPI with new method and this used the u-boot-splx4.sfp.

Let me test for sd card with new method and will update you ASAP.

Hi,

I am also facing issues at my end. Please allow some more time.

Will update you ASAP.

Hi,

I believe same query from your side, my another colleague is also handling.

We are checking internally, will update you ASAP.

Hi,

Please follow the below link to build the bootloader for Cyclone V.

https://www.rocketboards.org/foswiki/Documentation/BuildingBootloaderCycloneVAndArria10#Cyclone_V_SoC_45_Boot_from_SD_Card

1.Get hwlibs, install toolchain

cd $TOP_FOLDER

git clone https://github.com/altera-opensource/intel-socfpga-hwlib

cd intel-socfpga-hwlib/tools

./install_linaro.sh

./generate_doxygen.sh

export PATH=`pwd`/gcc/bin:$PATH

2.Build uboot from above shared link for Sd card.

3.Build Application

cd $TOP_FOLDER

cd intel-socfpga-hwlib/examples/CVAV/Altera-SoCFPGA-HardwareLib-Timer-CV-GNU/

# build once to bring hwlibs code

make SEMIHOSTED=0 MEMORY=ddr

# cleanmak

make clean

# change hwlibs link address to match what U-Boot wants

sed -i 's/0x00100040/0x01000040/g' hwlib/src/linkerscripts/cvav-ddr.ld

# move stack out of the way just in case

sed -i 's/0x80000/0x00200000/g' hwlib/src/linkerscripts/cvav-ddr.ld

# build again with the new address

make SEMIHOSTED=0 MEMORY=ddr

# create binary file

arm-eabi-objcopy -O binary application.elf application.bin

# create img file

$TOP_FOLDER/cv_soc_devkit_ghrd/software/bootloader/u-boot-socfpga/tools/

mkimage -A arm -T standalone -C none -a 0x01000040 -e 0x01000040 -n "bare-metal image" -d application.bin application.img

4.Build Image

cd $TOP_FOLDER

cat cv_soc_devkit_ghrd/software/bootloader/u-boot-socfpga/spl/u-boot-splx4.sfp \

intel-socfpga-hwlib/examples/CVAV/Altera-SoCFPGA-HardwareLib-Timer-CV-GNU/application.img \

> final-image.bin

5.create Sd card image

cd $TOP_FOLDER/sd_card

cp ../cv_soc_devkit_ghrd/software/bootloader/u-boot-socfpga/final-image.bin .

cd $TOP_FOLDER/sd_card

sudo python3 ./make_sdimage_p3.py -f \

-P final-image.bin,num=3,format=raw,size=10M,type=A2 -s 80M -n sdimage.img

Hi,

I believe your enquiry has been answered. With that, I now transition this thread to community support.

Thank you.

Hi,

0x01000040 is to load or run your application from the DDR.

0x00200000 is to resize your stack size for application on DDR.

This depend on your design and user config for selection the different partition like .stack, .heap, .ro, .data, .text, etc in you application linker script.

And, I believe your original query has been answered and resolved. With that, I now transition this thread to community support.

If you have any other query then I suggest you to post new case on the forum, we will assist you further.

Thank you.
