I'm using stm32H750B-DK and i'm trying to send a frame via LIN protocole every one second .
but when i run the code nothing happen .
when debugging i found that the code blocked in an endless loop in SCB_EnableDCache() function
Solved! Go to Solution.

I didn't reproduce your behavior from my side by stepping over SCB_EnableDCache(). Do you have another board to do the same test?

No i don't But like i said toggling the led and TouchGFX are working fine .
But toggling the led didn't work unless i created a task and not in the while loop

There is no data sent from the touchGFX .But when i used the stlink port to send it worked but when i use the Arduino connectors TX/RX it didn't work

This is a TouchGFX issue not related to the original question "endless loop in SCB_EnableDCache()".
