Data acces error on MR-CANHUB344

Hey,

I have set up a couple of interrupts using the Platform and Gpt driver. I wanted to add a second PIT hardware module. After setting it up I now get a hardfault during installation of the Gpt driver:
BusFault: A precise (synchronous) data access error has occurred.
Possible BusFault location: 0x400B4000.
HardFault: A fault has been escalated to a hard fault.

I'm probably doing something wrong in the driver config.

Please let me know if you have a solution.

Hi,

it could be due to having PIT_1 clock gated off. Check if module clock is enabled.

BR, Petr
