Hello everyone,

I´m developing a project that will use a MK22FN1M0VLQ12 processor.

I found and downloaded a MQX build targeted to MK22FN512 processors.

Do I have to make changes in the PSP files of this build?

If so, what should I change?

Is there a guide to follow as there is for porting BSP?

Thank you very much.

Best Regards.

You can use the PSP contained in the TWR-K22F120M, however if you are using the cloningwizard tool I suggest to clone all the MQX libraries.

Hello Francisco,

For creating custom BSP, the most crucial step is to select correct baseline BSP to clone from. The idea is to start with a BSP for a chip that is the most similar to the custom one.

For the MK22FN1M0VLQ12 I suggest to use the FRDMK22F120M BSP as base.

You can change the PSP in order to create a new unique CPU ID.


Please check the below thread, I hope this helps!!

Have a great day,
Sol

Hello Sol, thank you for your repply.

I asked if I have to make a new PSP for my processor, not BSP.

So, do I have to make a new PSP for my processor or I can use the PSP contained in the TWR-K22F120M?

Thanks for your help.

Best regards.
