I'm trying to use rosserial on the STM32F7 and I've been following some tutorials online namely this, this and also this as I'm a Keil guy.

Unfortunately, I run into the

Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python with groovy Arduino

error. I've used tested with multiple UART ports and also used about 4 different timers on the board but I'm still running into the same issue.

Could anyone possibly throw some pointers my way?

Have you looked into micro-ros? I always had issues with rosserial as well....and thats why I am very excited about the progress micro-ros is making.

I ended up just streaming my data over UART and reconstructing it in ROS. Overhead was probably lower as well.
