omap5432 boot from sd ,but the display have nothing

dear my friend 

 I see the  /var/log/dmesg  ,but  it  has nothing , I see the sd ,it has  kernel file,and the  four switch1010 ,is there some  request  about   the  point  time of the power 

I view the sd/rootfs/var/log/dmesg，but it  has nothing  ,then I view  the  sd/rootfs/boot,  I  find  nothing  ,is  I  do something  wrong   when I  prepare  the sd  

thank you  very much 

Hi Michael,

As far as i understood your board doesn't  boot at all. If it doesn't boot how do you manage to try and read dmesg content.

If that is not the case please provide me with the content of your console after you powered your device.

 Hi  Boyk

Is still need other orders  on the host  after you powered your device, my board doesn't  boot at all, I want  to know how  to boot  the board  then I can write command  on the target, then I run a small program on board

thank you in advance
