Basic Requirements

Linux Kernel

This script will build the kernel, modules, device tree binaries and copy them to the deploy directory.
Download:

#user@localhost:~$
git clone https://github.com/RobertCNelson/sft-riscv-linux
cd sft-riscv-linux/

For v5.10.x (Prepatch):

#user@localhost:~/sft-riscv-linux$
git checkout origin/v5.10.x -b tmp

Build:

#user@localhost:~/sft-riscv-linux$
./build_kernel.sh

Root File System

Debian 10

User Password
debian temppwd
root root

Download:

#user@localhost:~$
wget -c https://rcn-ee.net/rootfs/debian-riscv64/2021-04-29/debian-sid-console-riscv64-2021-04-29.tar.xz

Verify:

#user@localhost:~$
sha256sum debian-sid-console-riscv64-2021-04-29.tar.xz
#sha256sum output:
56fbfd69119ed57495d04a14a7834ad20448fe5bb4a8611f40a57ff993d15f89  debian-sid-console-riscv64-2021-04-29.tar.xz

Extract:

#user@localhost:~$
tar xf debian-sid-console-riscv64-2021-04-29.tar.xz

Setup microSD card

We need to access the External Drive to be utilized by the target device. Run lsblk to help figure out what linux device has been reserved for your External Drive.

#Example: for DISK=/dev/sdX
lsblk
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 465.8G  0 disk
├─sda1   8:1    0   512M  0 part /boot/efi
└─sda2   8:2    0 465.3G  0 part /                <- Development Machine Root Partition
sdb      8:16   1   962M  0 disk                  <- microSD/USB Storage Device
└─sdb1   8:17   1   961M  0 part                  <- microSD/USB Storage Partition
#Thus you would use:
export DISK=/dev/sdb
#Example: for DISK=/dev/mmcblkX
lsblk
NAME      MAJ:MIN   RM   SIZE RO TYPE MOUNTPOINT
sda         8:0      0 465.8G  0 disk
├─sda1      8:1      0   512M  0 part /boot/efi
└─sda2      8:2      0 465.3G  0 part /                <- Development Machine Root Partition
mmcblk0     179:0    0   962M  0 disk                  <- microSD/USB Storage Device
└─mmcblk0p1 179:1    0   961M  0 part                  <- microSD/USB Storage Partition
#Thus you would use:
export DISK=/dev/mmcblk0

Erase partition table/labels on microSD card:

sudo dd if=/dev/zero of=${DISK} bs=1M count=10

Create Partition Layout:
With util-linux v2.26, sfdisk was rewritten and is now based on libfdisk.

#Check the version of sfdisk installed on your pc
sudo sfdisk --version
#Example Output
sfdisk from util-linux 2.27.1
#sfdisk >= 2.26.x
sudo sfdisk ${DISK} <<-__EOF__
4M,,L,*
__EOF__
#sfdisk <= 2.25.x
sudo sfdisk --unit M ${DISK} <<-__EOF__
4,,L,*
__EOF__

Format Partition:

for: DISK=/dev/mmcblkX
sudo mkfs.ext4 -L rootfs ${DISK}p1
 
for: DISK=/dev/sdX
sudo mkfs.ext4 -L rootfs ${DISK}1

Mount Partition:
On most systems these partitions may be auto-mounted…

sudo mkdir -p /media/rootfs/
 
for: DISK=/dev/mmcblkX
sudo mount ${DISK}p1 /media/rootfs/
 
for: DISK=/dev/sdX
sudo mount ${DISK}1 /media/rootfs/

Install Kernel and Root File System

To help new users, since the kernel version can change on a daily basis. The kernel building scripts listed on this page will now give you a hint of what kernel version was built.

-----------------------------
Script Complete
eewiki.net: [user@localhost:~$ export kernel_version=5.X.Y-Z]
-----------------------------

Copy and paste that “export kernel_version=5.X.Y-Z” exactly as shown in your own build/desktop environment and hit enter to create an environment variable to be used later.

export kernel_version=5.X.Y-Z

Copy Root File System

#user@localhost:~$
sudo tar xfvp ./ddebian-*-*-riscv64-*/riscv64-rootfs-*.tar -C /media/rootfs/
sync
sudo chown root:root /media/rootfs/
sudo chmod 755 /media/rootfs/

Setup extlinux.conf

#user@localhost:~$
sudo mkdir -p /media/rootfs/boot/extlinux/
sudo sh -c "echo 'label Linux ${kernel_version}' > /media/rootfs/boot/extlinux/extlinux.conf"
sudo sh -c "echo '    kernel /boot/vmlinuz-${kernel_version}' >> /media/rootfs/boot/extlinux/extlinux.conf"
sudo sh -c "echo '    append console=ttyS0,115200 root=/dev/mmcblk0p1 ro rootfstype=ext4 rootwait' >> /media/rootfs/boot/extlinux/extlinux.conf"
sudo sh -c "echo '    fdtdir /boot/dtbs/${kernel_version}/' >> /media/rootfs/boot/extlinux/extlinux.conf"
sudo sh -c "echo '    devicetree /boot/dtbs/${kernel_version}/starfive/starfive_vic7100_evb.dtb' >> /media/rootfs/boot/extlinux/extlinux.conf"

Copy Kernel Image

Kernel Image:

#user@localhost:~$
sudo cp -v ./sft-riscv-linux/deploy/${kernel_version}.Image /media/rootfs/boot/vmlinuz-${kernel_version}

Copy Kernel Device Tree Binaries

#user@localhost:~$
sudo mkdir -p /media/rootfs/boot/dtbs/${kernel_version}/
sudo tar xfv ./sft-riscv-linux/deploy/${kernel_version}-dtbs.tar.gz -C /media/rootfs/boot/dtbs/${kernel_version}/

Copy Kernel Modules

#user@localhost:~$
sudo tar xfv ./sft-riscv-linux/deploy/${kernel_version}-modules.tar.gz -C /media/rootfs/

File Systems Table (/etc/fstab)

#user@localhost:~/$
sudo sh -c "echo '/dev/mmcblk0p1  /  auto  errors=remount-ro  0  1' >> /media/rootfs/etc/fstab"

Remove microSD/SD card

sync
sudo umount /media/rootfs

Could these build output files be used if someone does not want to compile themselves?

Hey @drewfustini not yet… still trying to get a to a login without kernel opp’s… :wink:
