OK335xD7寸电容屏使用故障
OK335xD连接7寸电容屏,当点击触摸屏时,返回如下信息,烧录的系统光盘提供的linux,麻烦问下飞凌的工程师,这是软件问题还是硬件问题,是驱动没有加载还是硬件故障?omap_i2c omap_i2c.2: Arbitration lost
omap_i2c omap_i2c.2: timeout waiting for bus ready
msg ft5x0x_i2c_rxdata i2c read error: -5
omap_i2c omap_i2c.2: controller timed out
msg ft5x0x_i2c_rxdata i2c read error: -110
msg ft5x0x_i2c_rxdata i2c read error: -5 说明驱动加载且进行i2c读操作了,超时应该是i2c硬件问题,用示波器看看i2c硬件或屏幕软排线问题
