- Building the SD Card under Quartus PRO 21.3
Introduction¶
Building the SD Card from the Quartus Project Makefile¶
Prerequisites¶
- Linux (tested on Ubuntu 18.04)
- libguestfs-tools insteall
sudo apt-get install libguestfs-tools
- vmlinux set a readable (note: this needs to be done every time the kernel is upgraded)
sudo chmod a+r /boot/vmlinuz*
Steps¶
- Copy the filesystem tarball built from yocto (mitysom-image-base-mitysom-a10s.tar.gz) to the software folder in the reference FPGA project
- Enter the following command that will allow you to use the Quartus tools from the command line. Note that the NIOS2 is not required in the design, this is just a convenience script to update your shell path.
/opt/intelFPGA_pro/21.3/nios2eds/nios2_command_shell.sh
- Run the following command to build the SD card image
make sd_image
Outputs¶
Description | Location |
SD Card Binary | <Quartus Project Folder>/sd_card.img |
ADVANCED: Updating Individual Parts¶
Updating the u-Boot SPL¶
If you make changes to the HPS pin multiplexing options to your project, you will need to rebuild and update the SPL image and the FPGA fit_spl_fpga.itb file (contains the peripheral RBF image). Critical link recommends updating the u-Boot SPL and u-Boot TPL (below) and FPGA files at the same time.
To update the FPGA RBF images, see Updating the FPGA Image
Installing From Linux On the MitySOM_A10S via ethernet¶
- scp the SPL image to the /tmp folder
scp software/bootloader/u-boot-socfpga/spl/u-boot-splx4.sfp root@your.boards.ip.addr:/tmp
- flash the image onto the SD partition
dd if=/tmp/u-boot-splx4.sfp of=/dev/mmcblk0p2 bs=512 && sync
Installing From a Linux Host using an SD-Card reader¶
Please note the X in the following example of /dev/sdX is a placeholder, you will need to find out what your machine enumerates your sd card's second partition as and replace the X with it.
- Plug in the SD Card reader
- Make sure it isn't mounted
sudo umount /dev/sdX
- Write the new u-boot environment over the old
dd if=software/bootloader/u-boot-socgpa/spl/u-boot-splx4.sfp of=/dev/sdX bs=512 && sync
Updating U-Boot TPL¶
Installing From Linux On the MitySOM_A10S via ethernet¶
- On the MitySOM-A10S, mount the FAT partition
mount /dev/mmcblk0p1 /mnt
- On the host, copy the FPGA files to the MitySOM-A10S using a windows command line or linux command line and SCP
scp software/bootloader/u-boot-socgpa/u-boot.img root@your.boards.ip.addr:/mnt
Installing From a Linux or Windows Host using an SD-Card reader¶
Simply copy the software/bootlaoder/u-boot-socgpa/u-boot.img file onto the FAT partition that appears when teh card is inserted into the reader.
Updating U-Boot Environment¶
Installing From Linux On the MitySOM_A10S via ethernet¶
- On the host, scp the SPL image to the /tmp folder
scp software/bootloader/u-boot-socfpga/ubootenv.bin root@your.boards.ip.addr:/tmp
- On the MitySOM-A10S, flash the image at 512 bytes off the base position of the card
dd if=/tmp/ubootenv.bin of=/dev/mmcblk0 bs=512 seek=1 && sync
Installing From a Linux Host using an SD-Card reader¶
Please note the X in the following example of /dev/sdX is a placeholder, you will need to find out what your machine enumerates your sd card.
- Plug in the SD Card reader
- Make sure it isn't mounted
sudo umount /dev/sdX
- Write the new u-boot environment over the old
dd if=software/bootloader/u-boot-socgpa/ubootenv.bin of=/dev/sdX bs=512 seek=1 && sync
Updating the FPGA image¶
Copy the software/bootloader/u-boot-socfpga/fit_spl_fpgfa.itb (contains the peripheral RBF) and core RBF to the 1st partition, which is formatted as FAT. Please note they need to have the same name as the originals for u-boot to find them.
Using the booted Arria10 to update the files¶
- On the MitySOM-A10S, mount the FAT partition
mount /dev/mmcblk0p1 /mnt
- scp the FPGA files to the partition using a windows command line or linux command line and SCP
scp software/bootloader/fit_spl_fpga.itb root@your.boards.ip.addr:/mnt scp software/bootloader/*.core.rbf root@your.boards.ip.addr:/mnt
Using an SD card reader on Windows or Linux¶
- install the card
- copy the files onto the FAT partition (only one available on Windows)
