Atmark Techno Armadillo-800 EVA

Introduction

This is the Wiki for the Renesas R-Mobile A1-based Atmark Techno Armadillo-800 EVA board. Refer to the R-Mobile page for information about Renesas' R-Mobile SoC family.

Serial Console

Use a serial cable to connect to "CON22". Serial settings are 115200 8N1.

Booting Linux

 * Kernel config: shmobile_defconfig
 * Kernel image: arch/arm/boot/zImage.dtb
 * DTB: arch/arm/boot/dts/r8a7740-armadillo800eva.dtb

Create a zImage with appended DTB:

make zImage dtbs
cat arch/arm/boot/zImage arch/arm/boot/dts/r8a7740-armadillo800eva.dtb > arch/arm/boot/zImage.dtb
# Hermit seems to drop the last byte if size is odd
dd if=/dev/zero bs=16 count=1 >> arch/arm/boot/zImage.dtb

Hermit-At boot command:

tftpboot <armadillo-ip-addr> <server-ip-addr> --kernel=zImage.dtb
