In the older driver model that worked with S32DS for ARM, there was an API for timer delay that supported bare metal implementation. In the new Real Time Driver model, I cannot find an equivalent. Trying to do that creates an error; please see the attached screen shot.
Is there a way to do that?
Details about the project:
MCU: S32K148 in 144 pin configuration
System OS: Bare metal
RTD version: 3.0.0
Driver configuration: Low level (non-Autosar); please see the screenshot.
Hello @danielmartynek
Thank you for the update. This is in agreement with what I had found. A couple of follow ups:
1. So there is no equivalent of OSIf_TimeDelay() in the Real Time drivers? I am seeing such gaps in other parts of the driver APIs as well which makes porting existing code somewhat non-trivial.
2. Are these APIs uniform across all MCAL implementations? Put another way, if I use hardware and MCAL implementation from another vendor who claims MCAL compliance, can I expect all these APIs to be available in their driver implementation? (You can read this the other way around also; if I am migrating to NXP FROM another vendor who claims MCAL compliance, can I expect NXP drivers to provide all the APIs that the other vendors driver provides?)

Hi @durga_choudhury,
Refer to OsIf.h, there are these functions:
OsIf_Init(),
OsIf_GetCounter(),
OsIf_MicrosToTicks(),
OsIf_GetElapsed(),

Hello @durga_choudhury,
1.
No there is no such function, individual drivers use the OsIf APIs, for example:
2.
RTD includes:
- AUTOSAR MCAL drivers
- Low-level IP-level drivers
Only the highest (AUTOSAR) layer of MCAL is portable.
For example, Adc_Init().
But OsIf_GetElapsed() is not an AUTOSAR API, It is NXP-specific.

Daniel
