I have the RappId Bootloader flashed to my S32K144 and successfully flashing appl. by Serial.

 

But  I,m having trouble initializing LPUART1 in my application.

 

Regardless what I try to do I cant change the baud rate from 57600bps.

 

Finally I realized that the LPUART1 gets initialized in bootloader, right?

 

I have tried to set, and then clear, the Reset in GLOBAL reg. and then reinitialize LPUART1, -but don't work.

Getting stuck with 57600 even when i try to set 9600 (LPUART1->BAUD = 0x0F000034;)

 

Waht am I doing wrong?

 

And also, are there more modules/peripherals/clocks initialized in the bootloader that I should know about?

 

Thank you!
