s32k144 FTM0 interrupt

Hi,

 

Im using S32 sdk ear 0.8.1 and fsl_interrupt_manager to install a interrupt handler for FTM0. And it works.

 

But a comment in S32K1xx_DMA_Interrupt_mapping.xlsm makes me confused.

NVIC interrupt id 42, which the sdk uses, is marked as Reserved and has comment "was FTM0".

 

1) What does this mean? Will this interrupt not be available/usable in a future revision of s32k144?

2) The SDK does not expose interrupt id 104 (FTM0: Counter overflow). IRQn_Type only defines id up to 98.

3) I would like some guidens  on how to proceed. Can I ignore this issue or will a future SDK fix this?

 

BRs

Hi,

1) yes, there are differences between S32K144 revisions. FTM interrupts located in vector numbers 42, 43 and 44 were removed and placed in vectors 99 onwards in cut2 (mask 0N47T). The excel sheet shows relevant compatibility comments.

2-3) the S32 sdk ear 0.8.1 supports cut1 MCU (mask 0N77P) and this vector table should be fixed in next revision, I think.

BR, Petr
