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
Remote Control
| Operation | Signal A | Pin A | Signal B | Pin B | Connector needed | Comments |
| Reset | JTAG nSRST | CON6 pin 15 | GND | CON6 pin 16 | 2-pin female Mini-PV | |
| Wake-Up | PORT95 | CON15 pin 52 | GND | CON15 pin 38 | Solder 2.54mm pin header + 2x 1-pin female Mini-PV | Needs ARM: dts: armadillo800eva: Enable PORT95 for wake-up |
