Hi Team,

I am using stm32h753 controller, While receiveing data in the UART. Rx buffer index is not always Rxbuff[0]. Data is received randomly in the different index.

Here i am attaching the reference.

Can you post the code how you receive data? It is unclear from your print screen.

Can't you just paste more complete code?

How large is the buffer?

You ignore error status from the function.

You ignore the fact data reception may be of different sizes, or shift in alignment/synchronization.​
