the more cryptic the question ...
Please furnish a more detailed description of the circumstances that cause 'your' fault. With HW components it could be a simple timing issue, such as write before a necessary read is performed. Other possibilitys exist such as Buffer overflows etc.
Best way to proceed is to post your project here. That enables all to have a look at what you have so far and maybe 'see' a problem.

BTW: I think, this issue belongs into the HW section of the forum (not SW).
Gruss/regards IKT
