ADV7441 HDMI输入源分辨率 转换问题

农民工程师

现在遇到以下问题：1. IO Map R0x6F[0]是否为1 (是否检测到cable接入)2. IO Map R0x6A[4]是否为1 (是否检测到HDMI Clock)3. HDMI Map R0x04[1]是否为1 (是否HDMI PLL lock)4. HDMI Map R0x05[6]是否为1 (HDMI 内容是否加密)5. HDMI Map R0x07[5]是否为1 (De generation是否锁定) 问题：1HDMI Map R0x05[6]是否为1 (HDMI 内容是否加密) 我们测试的结果为0，会不会影响Hi3520D数据的接受？2HDMI Map R0x04[1]是否为1 (是否HDMI PLL lock)# ./i2c_read 0x980x6aGPIO_I2C_READ_BYTE, dev_addr=0x98 reg_addr=0x6a value=0x53# ./i2c_read 0x980x6aGPIO_I2C_READ_BYTE, dev_addr=0x98 reg_addr=0x6a value=0x53# ./i2c_read 0x980x6aGPIO_I2C_READ_BYTE, dev_addr=0x98 reg_addr=0x6a value=0x53# ./i2c_read 0x980x6aGPIO_I2C_READ_BYTE, dev_addr=0x98 reg_addr=0x6a value=0x53# ./i2c_read 0x980x6aGPIO_I2C_READ_BYTE, dev_addr=0x98 reg_addr=0x6a value=0x53# ./i2c_read 0x980x6aGPIO_I2C_READ_BYTE, dev_addr=0x98 reg_addr=0x6a value=0x53# # # ./i2c_read 0x980x6aGPIO_I2C_READ_BYTE, dev_addr=0x98 reg_addr=0x6a value=0x11# ./i2c_read 0x980x6aGPIO_I2C_READ_BYTE, dev_addr=0x98 reg_addr=0x6a value=0x51# ./i2c_read 0x980x6aGPIO_I2C_READ_BYTE, dev_addr=0x98 reg_addr=0x6a value=0x11# ./i2c_read 0x980x6aGPIO_I2C_READ_BYTE, dev_addr=0x98 reg_addr=0x6a value=0x11# ./i2c_read 0x980x6aGPIO_I2C_READ_BYTE, dev_addr=0x98 reg_addr=0x6a value=0x11# ./i2c_read 0x980x6aGPIO_I2C_READ_BYTE, dev_addr=0x98 reg_addr=0x6a value=0x11我们测试的结果非常不稳定？这是什么原因造成的？3：我们测试对输入源分辨率和帧率有什么要求？
