Davinci i2c_rdwr.out 错误



我的硬件:APPRO DM8127 IPNC CAM, RDK 3.5。想测试一下sensor,型号为MT9J003,让他输出color bar。但是出错了,如下:

root@DM8127_IPNC:/opt/ipnc/bin# ./i2c_rdwr.out -r 0x6d 0x0600 1  ERROR  (osa_i2c.c|OSA_i2cTestMain|263): OSA_i2cOpen( instId = 3 ) root@DM8127_IPNC:/opt/ipnc/bin# ./i2c_rdwr.out -r 0x36 0x0600   ERROR  (osa_i2c.c|OSA_i2cTestMain|263): OSA_i2cOpen( instId = 3 )

我看MT9J003的datasheet,slaveaddr应该是0x6D(或者右移一位为0x36),test mode 的寄存器是0x0600 ,help~~~
