Examples or tutorials for using SDHC in MPC5748G

Hi,

I am trying to insert a micro SD card in the corresponding SDHC port of MPC5748G and use it for saving and loading file. Since I am quite new about embedded system, could you introduce me a good examples or tutorials about how to use SDHC? (I understand the communication between the board and the SD card is done by SPI communication and the port numbers are provided in the pinmap (https://www.nxp.com/docs/en/quick-reference-guide/DEVKIT-MPC5748G-QSG.pdf), but I have no idea what to do for further progress.)

Best,

Jongwon

Hi,

SW examples can be found in S32 Design Studio IDE:

https://www.nxp.com/design/software/development-software/s32-design-studio-ide/s32-design-studio-for-power-architecture:S32DS-PA

The examples can be found in this folder:

c:\NXP\S32DS_Power_v2.1\S32DS\software\S32_SDK_S32PA_RTM_3.0.3\examples\MPC5748G\demo_apps\

Regards,

Lukas

Ah, I am a Linux user, and it seems like there is no SDHC example on the Linux version of S32DS. Could you provide me any resources also available in S32DS for Linux? (Just sharing the example file will be also welcomed!)

Hi,

I have bad news... The SDK is integrated only in Windows version:

Unfortunately we do not have other examples than this one in SDK.
