11.1.4 Remote Processor Messaging
11.1.4.1 Test Name
- mxc_mcc_tty_test.out
11.1.4.1.1 Location
/unit_tests/Remote_Processor_Messaging
11.1.4.1.2 Functionality
Cortex-A와 Cortex-M 코어 사이의 통신을 테스트한다.
11.1.4.1.3 Configuration
i.MX RPMsg 테스트 프로그램을 실행하려면, 아래 작업을 수행한다. 적절한 Cortex-M4 프로세서 RTOS와 Linux 이미지가 사용되는지 확인한다. 아래는 i.MX7Dual 보드의 예이다:
- rpmsg_pingpong_sdk_7dsdb.bin → i.MX7Dual SDB 보드에서 사용되는 핑퐁 테스트
- rpmsg_str_echo_sdk_7dsdb.bin → i.MX7Dual SDB 보드에서 사용되는 tty 문자열 에코 테스트
- rpmsg_pingpong_sdk_7dval.bin → i.MX7Dual 12x12 LPDDR3 ARM2 보드에서 사용되는 핑퐁 테스트
- rpmsg_str_echo_sdk_7dval.bin → i.MX7Dual 12x12 LPDDR3 ARM2 보드에서 사용되는 tty 문자열 에코 테스트
Cortex-M4 프로세서 RTOS 이미지를 로드하고, U-Boot에서 시작한다. TFTP 서버나 U-Boot에서 부팅 가능한 SD 카드에서 Cortex-M4 프로세서 RTOS 이미지를 로드한다.
- TFTP 서버에서 Cortex-M4 프로세서 RTOS 이미지를 로드한다:
- U-Boot로 부팅하고 중지한다.
- 아래 커맨드를 사용하여 응답하는 Cortex-M4 프로세서 RTOS 이미지를 TFTP에서 부팅한다.
=> dhcp 0x7f8000 10.192.242.53:rpmsg_pingpong_sdk_7dval.bin;
bootaux 0x7f8000- SD 카드에서 Cortex-M4 프로세서 RTOS 이미지를 로드한다:
- MFGtools를 사용하여 부팅 가능한 SD 카드를 생성한다.
- VFAT 파일 시스템으로 포맷된 첫 번째 파티션에 Cortex-M4 프로세서 RTOS 파일을 복사한다.
- U-Boot의 기본 Cortex-M4 프로세서 RTOS 이름을 변경한다.
=> setenv m4image '<The name of the M4/RTOS image>';saveCortex-M4 프로세서에서 사용하는 bootargs를 설정한다.
=> setenv run_m4_tcm 'if run loadm4image; then cp.b ${loadaddr}
0x7f8000 0x8000;
=> bootaux 0x7f8000; fi'; save"run run_m4_tcm"을 추가하여 원래의 bootcmd를 수정한다.
=> setenv bootcmd "run run_m4_tcm; <original contents of the
bootcmd>"; save참고
참고로 “uart_from_osc”는 Cortex-M4 프로세서 RTOS 이미지가 실행 중일 때, i.MX 6SoloX에서 필요로 한다. 따라서, i.MX 6SoloX에서 U-Boot의 mmcargs를 수정해야 한다.
=> setenv mmcargs 'setenv bootargs console=${console},
${baudrate} root=${mmcroot}, uart_from_osc';saveRPMsg 테스트 프로그램을 실행한다. imx_rpmsg_pingpong.ko와 imx_rpmsg_tty.ko가 빌드되어 있는지 확인한다. "insmod imx_rpmsg_pingpong.ko"와 "insmod imx_rpmsg_tty.ko"를 사용하여 테스트 프로그램을 실행한다.
참고
참고로 동시에 서로 다른 테스트 프로그램을 실행하지 않는다.
11.1.4.1.4 Use Case and Expected Output
아래 커맨드를 실행하고 RPMsg TTY 테스트를 시작할 때 RPMsg TTY 수신 프로그램이 백엔드에서 실행 중인지 확인한다.
# ./mxc_mcc_tty_test.out /dev/ttyRPMSG30 115200 R 100 1000 &
Expected output:
mxc_mcc_tty_test.out:
$ insmod imx_rpmsg_tty.ko
$ imx_rpmsg_tty rpmsg0: new channel: 0x400 -> 0x1!
$ Install rpmsg tty driver!
$ echo deadbeaf > /dev/ttyRPMSG30
$ imx_rpmsg_tty rpmsg0: msg(<- src 0x1) deadbeaf len 8
11.1.5 Watchdog (WDOG)
11.1.5.1 Test Name
- autorun-wdog.sh
- wdt_driver_test.out
11.1.5.1.1 Location
/unit_tests/Watchdog/
11.1.5.1.2 Functionality
예기치 않은 중단, 무한 루프 상황이나 프로그램 오류로부터 벗어나는 수단을 제공하여, 시스템 오류로부터 보호하는 Watchdog Timer 모듈을 테스트한다.
11.1.5.1.3 Configuration
None
11.1.5.1.4 Use Case and Expected Output
Use case
./autorun-wdog.sh
or
./wdt_driver_test.out 1 2 0 &
Expected output
This should generate a reset after 3 seconds (a 1 second timeout
and a 2 second sleep).
or
./wdt_driver_test.out 2 1 0
The system should keep running without being reset. This test
requires the kernel to be executed
with the "jtag=on" on some platforms. Press "Ctrl+C" to
terminate this test program.
