How to support micro SD card with file system on freeRTOS application

zohargolan1 — Thu, 29 Oct 2015 07:10:57 GMT

Hi,

I am using FreeRTOS integrated into Processor Expert and implementing it on K20 device.

How should I go about implementing a microSD interface with FAT file system.

Any comment will be highly appreciated

Hi Zohar,

I'm using FreeRTOS with FatFS in several projects, see FatFs | MCU on Eclipse . There are sources/examples available on GitHub (see the links in the articles).

I hope this helps,

Erich

Hi Erich,

As usual, thank you for the fast reply. The link you have send me is using the KSDK 1.2.0. I am using the freeROTS extention, which is not using the SDK. Is it going to be a problem or I can add the KSDK in processor expert?

Thank you,

Zohar

Hi Zohar,

you can use it either way: You can use only the SDK (there is a FatFS example in the SDK), or you can use the SDK with Processor Expert (but then it only suppports the fsl_* components), or you can use Processor Expert with the 'non-SDK' components. So you have freedom of choice :-)

Note that the FreeRTOS in the SDK is an older one (8.2.0) while the McuOnEclipse component is using the latest FreeRTOS (8.2.3).

I hope this helps,

Erich
