problem when using dm6437

We use dm6437 in two programs , both with  image sensor  , one is sensor LUPA-300( Cypress) , the other  sensor is MT9T001 (Micron) , 

The first one now can work properly , the second hasn't worked yet .

here i have two questions : 

1) To the first one , we use CCS3.3 and the power chip is  LTZK1767 ,  when the external power supply is 12V , it works properly ; but when the external power supply is 7V ,   once the program runs , either signed power faliure immediately or several minutes later , I am so confused.

2)To the second one , it hasn't work yet , and i download a program from the TI website named " evmd6437" , I am using the  psp_1_00_02_00 , I can only see the function definition in the file "psp_i2cApi.h" but no function body  , now  I want to see  PSP_i2cTransfer() function body , can anyone help me ?

    Erick,

    To your questions:

    1) I am not familiar with the power chip, but I would suggest you to make sure the I/O, core, and DDR voltage are correct. Please double check the voltage and compare against the range in the datasheet

    2) Most it is already in the generated library file (.lib). I am not sure if they include the source in the PSP, but you should always be able to do a global search inside PSP root directory.
