The Marvell MACCHIATObin is a family of cost-effective and high-performance networking community boards targeting ARM64bit high end networking and storage applications. With a offering that include a fully open source software that include U-Boot, Linux, ODP and DPDK, the Marvell MACCHIATObin are optimal platforms for community developers and Independent Software Vendors (ISVs) to develop networking and storage applications. The default kernel configuration provided by Marvell does not meet the container's system requirements. So need to reconfigure and compile the kernel to meet SEBA operation，and also u-boot. We provide a kernel configuration file that has been verified on the MACCHIATObin board for developers to use.
Marvell linux must apply with MUSDK provided kernel patches(see patches/linux in musdk repo
and relevant documentation).
U-boot version used: u-boot-2018.03-armada-18.09
Kernel version used: linux-4.14.22-armada-18.09
MUSDK version used: musdk-armada-18.09
Marvell provides detailed documentation on how to build bootloaders from source code. Note that checkout u-boot-2018.03-armada-18.09 branch is important. This page will walk you through the bootloader update process via network, i.e. using the TFTP server. In addition, you can use the USB Flash drive to update boot as following instructions:
Marvell>> usb reset
Marvell>> bubt flash-image.bin spi usb
Marvell>> reset
Marvell>> env default -a
Marvell>> env save
Make sure that the MACCHIATObin board does not experience power loss during the entire updating process, otherwise it will be bricked due to an unfinished bootloader update.
The U-Boot parameter for Micro SD card/USB boot can be found here,but the instructions of the page do not fully apply to 18.09.It needs to be changed a little bit.
Using Micro SD card:
Marvell>> setenv image_name boot/Image
Marvell>> setenv fdt_name boot/armada-8040-mcbin.dtb
Marvell>> setenv bootcmd 'mmc dev 1; ext4load mmc 1:1 $kernel_addr_r $image_name;ext4load \
mmc 1:1 $fdt_addr_r $fdt_name;setenv bootargs $console root=/dev/mmcblk1p1 rw rootwait \
pci=pcie_bus_safe cpuidle.off=1; booti $kernel_addr_r - $fdt_addr_r'
Marvell>> saveenv
Marvell>> run bootcmd
Using USB Stick:
Marvell>> setenv image_name boot/Image
Marvell>> setenv fdt_name boot/armada-8040-mcbin.dtb
Marvell>> setenv bootusb 'usb reset; ext4load usb 0:1 $kernel_addr_r $image_name; \
ext4load usb 0:1 $fdt_addr_r $fdt_name;setenv bootargs $console root=/dev/sda1 \
rw rootwait pci=pcie_bus_safe cpuidle.off=1;booti $kernel_addr_r - $fdt_addr_r'
Marvell>> saveenv
Marvell>> run bootusb
If U-Boot version is 17.10, you should repleace $kernel_addr_r/$fdt_addr_r by $kernel_addr/$fdt_addr.
The procedures to build kernel from source is almost the same, but there are still some points you need to pay attention to on MACCHIATObin board. Download Kernel Source:
mkdir -p ~/kernel/4.14.22
cd ~/kernel/4.14.22
git clone https://github.com/MarvellEmbeddedProcessors/linux-marvell .
git checkout linux-4.14.22-armada-18.09
Download MUSDK Package Marvell User-Space SDK(MUSDK) is a light-weight user-space I/O driver for Marvell's Embedded Networking SoC's. The MUSDK library provides a simple and direct access to Marvell's SoC blocks to networking applications and networking infrastrucutre:
mkdir -p ~/musdk
git clone https://github.com/MarvellEmbeddedProcessors/musdk-marvell .
git checkout musdk-armada-18.09
Linux Kernel needs to be patched and built in order to run MUSDK on the MACCHIATObin board:
cd ~/kernel/4.14.22/
git am ~/musdk/patches/linux-4.14/*.patch
Replace the default kernel configuration file with defconfig-mcbin-edge which enable necessary kernel modules needed by running kubernetes, also calico:
cp defconfig-mcbin-edge ~/kernel/4.14.22/arch/arm64/configs/mvebu_v8_lsp_defconfig
and then compile the kernel:
export ARCH=arm64
make mvebu_v8_lsp_defconfig
make -j$(($(nproc)+1))
Script is provided to facilitate build of the kernel image, the developer needs to run with root privileges:
./setup-macbin-kernel.sh
If kernel is compiled on the MACCHIATObin board, you can easily update kernel using the following instructions:
cd ~/kernel/4.14.22
make modules_install
cp ./arch/arm64/boot/Image /boot/
cp ./arch/arm64/boot/dts/marvell/armada-8040-mcbin.dtb /boot/
sync
reboot
and also refer to the wiki for MACCHIATObin to boot from removable storage.
SEBA as one of the IEC use cases, you can refer to README to manually install SEBA on Arm servers.
