Building at91bootstrap - second level bootloader for SAMA5D3X-CM
This bootloader is based on https://github.com/linux4sam/at91bootstrap, branch at91bootstrap-3.x
Setup the cross-compiler and CPU architecture
$ export ARCH=arm $ export CROSS_COMPILE=/opt/cross/arm-ronetix-eabi-8.3.0/bin/arm-ronetix-eabi-
Clone the latest revision of the repo
$ git clone git@github.com:ronetix/at91bootstrap.git -b at91bootstrap-3.10.4_rnx $ cd at91bootstrap
Configure and build
$ make sama5d3x_cm_nf_uboot_defconfig $ make
Build Results
| File Name | Description |
|---|---|
| binaries/at91bootstrap.bin | BIN image, should be programmed at address 0x0 |

Building Buildroot - a simple Linux System for SAMA5D3X-CM
Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation.
The home page of Buildroot is: https://buildroot.org
The Buildroot user manual can help you better understand how Buildroot works: http://www.buildroot.net/downloads/manual/manual.html
The Buildroot for SAMA5D3x is maintained by Microchip: https://www.linux4sam.org/bin/view/Linux4SAM/BuildRoot
Buildroot can build:
- at91bootstrap
- u-boot-at91
- linux-at91
- A cross-compiler
- Root filesystems of different types
Prerequisites
Host build system should be a Linux system with necessary software installed: http://buildroot.uclibc.org/downloads/manual/manual.html#requirement
In addition to these required packages, you should also install libssl-dev:
$ sudo apt-get install libssl1.0-dev
or, depending on your host distribution:
$ sudo apt-get install libssl-dev
Get sources
$ git clone https://github.com/linux4sam/buildroot-at91.git $ git clone https://github.com/linux4microchip/buildroot-external-microchip.git
$ cd buildroot-external-microchip/ $ git checkout linux4microchip-2022.10 -b buildroot-external-microchip-linux4microchip-2022.10
$ cd ../buildroot-at91/ $ git checkout linux4sam-2022.10 -b buildroot-at91-linux4sam-2022.10
Build
$ make atmel_sama5d3xek_defconfig $ make
Once compilation is done, the images have been generated in: ./output/image:
- at91bootstrap.bin
- rootfs.tar
- u-boot.bin
- u-boot-spl.bin
- zImage
- sama5d31ek.dtb
- sama5d33ek.dtb
- sama5d34ek.dtb
- sama5d35ek.dtb
- sama5d36ek.dtb
- rootfs.ubi
- rootfs.ubifs
Customizing Buildroot
AT91Bootstrap
$ BR2_EXTERNAL=../buildroot-external-microchip/ at91bootstrap3-menuconfig
U-BOOT
$ BR2_EXTERNAL=../buildroot-external-microchip/ make uboot-menuconfig
Linux Kernel
$ BR2_EXTERNAL=../buildroot-external-microchip/ make linux-menuconfig
RootFs
$ BR2_EXTERNAL=../buildroot-external-microchip/ make menuconfig
NAND Boot: Programming images
SAM-BA tool or PEEDI JTAG Flash Programmer can be used for programming the images into the NAND Flash.
All images should be programmed with 4-bit ECC.

|---|---|---|
| 0x00000000 | boot.bin | at91bootstrap, programmed with header 0xc0902405 |
| 0x00040000 | u-boot.bin | U-BOOT, third level bootloader |
| 0x00180000 | sama5d35ek.dtb | Device tree for Linux Kernel |
| 0x00200000 | zImage | Linux Kernel |
| 0x00F80000 | rootfs.ubi | Root file system |
