myrio auto start up logging problem

[wcchung33a]

hi all

i am working on a simple data logger for myrio。 i follow the basic structure(open write close)。 everything was fine when i use computer to rue the vi。 when i set the myRIO as auto start up , the myrio cannot create a text file and log。 then i try to power off and power on it again , still not working。

where the problem?

thanks

Hey Andy,

Can you attach your code so we can see what you're doing?
