SafeTI: SL_Init_Memory() does not accept ADC_RAMs as argument

Other Parts Discussed in Thread: HALCOGEN

According to TRM there is ADC modules in RM46&RM48, why SL_Init_Memory()-function does not accept them as argument? TRM table 2-7 does not specify anything special for those RAMs...

HALCoGen generated code performs ADC init via memoryInit()-function which actual execution related content is idential to SafeTI-version...

MIBSPI RAM has clear restriction in TRM, remark 4 in table 2-7 that modules has to be out of reset but SafeTI argument checker in SL_Init_Memory() doesn't check that one and code might end into endless waiting loop (tested this :)) but then at same time it prevents ADC usage which shouldn't have any restrictions and which works by using HalCoGen-generated-function - I am confused...


Secondary question: Is there any benefit to use internal memory initializer via SL_Init_Memory() or memoryInit() for MIBSPII (HALCoGen does re-initialize those modules) if according to TRM for SPIGCR0 says that SPI RAM init is always done when module is released from internal reset?

    Hello Jarkko,

    I've forwarded your question to one of our SW leads and they or one of their team members should be able to get back to you shortly.

    Hi Jarkko

    You are right, It's a feature missing in SL_Init_Memory() API of SafeTI Diagnostics Library(SDL), I raised a ticket (SDOCM00122888) to follow up on ADC support for Init memory, so that it is addressed in next SDL release.

    MIBSPI is a Special module which has this inbuild feature, So yes, to save time you need not do the memory Init as part of SL_Init_Memory() or memoryInit(). mibspiInit() function in HALCoGen will take care of it. Again it's up to the user application, if time budget is not a concern it's no harm in doing it though.
