Other Parts Discussed in Thread: TPS62355, TPS65911

Hi,

I have a DM8127 board from Appro , IPNC RDK 3.0,  I can boot the board successfully .

But when I run "i2cdetect -l" , I only see three device on i2c-1 bus, the device is tps65911,tps62355 and aic3104, I know this three device is on i2c[0] bus, and mt9j003 is on i2c[1] bus , Now I want to know weather I can see mt9j003 register values in ARM side by using command i2cdump?. Is mt9j003 controled by M3 core and cannot be detected in ARM side?

Can someone help me?Thanks!

    Hi yang,

     

    Yes, I2c-1 is available on M3, why do you need to know the register settings?

    Thanks for your quick reply.

    I have a costom board , which have SN65LVDS324 on the same bus with mt9j003 , I want to config the SN65LVDS324 through a script like below on ARM side.

    i2cset -f -y  0x2d 0x09 0x34

     i2cset -f -y  0x2d 0x0A 0x60

     i2cset -f -y  0x2d 0x0B 0x07

     i2cset -f -y  0x2d 0x0C 0x80

    but now it seems cannot achrive, because i2cdetect cannot find device on i2c[2] bus . Is there any way to let ARM config LVDS324?
