Introduction
This is the Wiki for the Renesas R-Mobile APE6 APE6-EVM board. Refer to the R-Mobile page for information about Renesas' R-Mobile SoC family.
Serial Console
Use a micro-USB cable to connect to "Console". Serial settings are 115200 8N1.
Booting Linux
* Kernel config: shmobile_defconfig * Kernel image: arch/arm/boot/uImage * DTB: arch/arm/boot/dts/r8a73a4-ape6evm.dtb
Create a uImage:
make LOADADDR=0x40008000 uImage
U-Boot boot command:
tftp 41000000 uImage tftp 50000000 r8a73a4-ape6evm.dtb bootm 41000000 - dtb 50000000
Suspend-to-RAM
Procedure
The system can be suspended using:
echo mem > /sys/power/state
Wake-Up Sources
Suspend-to-RAM supports the following wake-up sources:
- gpio-keys: Wake-up using push button S16.
- sh-sci (Serial): Disabled by default
Remote Control
Operation | Signal A | Pin A | Signal B | Pin B | Connector needed | Comments |
Reset | JTAG nSRST | X12 pin 15 | GND | X12 pin 16 | 2-pin female Mini-PV | nSRST is an 1.8V signal! |
Wake-Up | PORT1/DU0_DR1 | X8 pin 16 | GND | X8 pin 28 | Samtec QTE-020 | Needs ARM: dts: ape6evm: Enable PORT1 for wake-up from renesas-drivers#topic/board-farm |
Run U-Boot from JTAG
Start openocd, one can use the similar and upstream Stout board file.
openocd -f interface/ftdi/flyswatter2.cfg -f board/renesas_stout.cfg -c 'adapter_khz 300'
Halt the target, load U-Boot and jump to it.
halt load_image /path/to/uboot.bin 0xe8200000 resume 0xe8200000
