Find a example code of using driver / interfaces for MPC5748G?

tobiasfuelle — Fri, 01 Apr 2016 15:11:29 GMT

Hello all,

I want to start testing my MPC5748G with some reference or example projects (can be baremetal without OS as well). If possible, I like to include and integrate several drivers in the future:
- CAN bus

- LIN bus

- FlexRay bus
- Ethernet port
- SPI port

Could you help me to find projects for that MCU or for similar ones?

Thanks,
kind regards,

Tobias

You need AN4830, which contains all but FlexRay example. For FlexRay you'll have to use proprietary stack from AUTOSAR supplier or Vector (due to licensing issues).

Hello Aleksandar,

thank you very much. The examples are very helpful. But I am struggeling with the declaration of the function, since I can't find its definition:

__ghs_board_devices_init_AFTER_main(void);

Is that the actual name of it or will I substitute board_devices with its name?
Thanks,
regards,
Tobias

Hi Tobias,

__ghs_board_devices_init_AFTER_main is defined in

<zip file>\AN4830_rev1_SW\MPC5748G_rev<revision>_silicon\tgt\libboardinit\mpc5748g_rev1.ppc

Normally, compiler should find it, since demo projects contain and build

tgt\resources.gpj

which builds libboardinit.gpj, containing mentioned file.

BR,

Alex
