MQX & 5225x with different clock speed

[iaccy]

I am using a crystal of 7M3728MHz and letting the pll multiply it by 10. I've done this outside the BSP/PSP source, i.e. in the startup task. I know I can change it in the bsp_init.c file but where do I make the changes in MQX so that it knows it has a 73M728Hz Fsys reference and not 80MHz?

Hello,

To do that, you need to create/modify a BSP. It's explained in MQXUG.pdf in chapter 5, how to developing a new BSP.
