[参考译文] DLPDLCR2000EVM：在 BeagleBone Black 上未检测到 I2C

我通过 Cape 覆层解决了 I2C 连接。

echo DLPDLCR2000 | sudo tee /sys/devices/platform/bone_capemgr/slots

（来自  DLP2000：带 BeagleBone Black 的 DLP LightCrafter Display 2000 EVM 无法启动） 

但是、我遇到了一个 新问题 ： 使用命令后、无法在投影仪上启动 BeagleBone Desktop。

i2cdetect -r -y 2
i2cset -y 2 0x1b 0x0b 0x00 0x00 0x00 0x00 i
i2cset -y 2 0x1b 0x0c 0x00 0x00 0x00 0x1b I

它 仅显示启动界面。 另外、我遵循了  第 11 步至第 14 步。  她没有说话,只是缓缓的低下头。
