eMcem_Eim_SetupInjectionChannel return fail

Hi Nxp Community,

I am thankful for having a chance to consult about something. I am stuck in EIM because api eMcem_Eim_SetupInjectionChannel that is necessary to inject faults always return fail. Access to pEim->EICHD[u16EimChannel].WORD[0] (address is 0x40258100) causes to BusFault_Handler(). Is there any solution? looking forward to your reply.

main() is as belows:

BR,

Sylvia

Hello Sylvia,

by default the clock for EIM module is disabled so when trying to access EIM registers a bus fault is generated. In order to enable clocks for EIM module, there can be used Power_Ip driver.

In the configuration it is needed to add POWER module:

Then in configuration of POWER module enable clock for EIM:

And then in main function call Power_Ip_SetMode API to enable the EIM clock:
Power_Ip_SetMode(&Power_Ip_aModeConfigPB[0]);

Best Regards,
Frantisek
