ti-processor-sdk是怎样识别板子的

我用i-processor-sdk-linux-am335x-evm-05.03.00.07的create-sdcard.sh脚本制作了一张SD卡,将该卡插入beagleboneblack中,查看LED设备,显示如下:

root@am335x-evm:~# ls /sys/class/leds/

beaglebone:green:heartbeat  beaglebone:green:mmc0       beaglebone:green:usr2       beaglebone:green:usr3

但是当我将SD卡插入入门套件时显示

root@am335x-evm:~# ls /sys/class/leds/

evmsk:green:heartbeat  evmsk:green:usr0

evmsk:green:mmc0       evmsk:green:usr1

两者不一样,程序在哪个地方通过什么方法来识别板子的?
