AM335x ICE V2 - dosfs support for SD card.

Brady Rutherford

Other Parts Discussed in Thread: SYSBIOS, AM3359

I'm working with the enetLwip_sysbios example provided in the SYSBIOS Industrial SDK 01.01.00.06. As recommend in the SDK's User's Guide I have installed:

Code Composer Studio 6.0.1.00040
SYSBIOS 6.41.00.26
XDC 3.30.05.60
NDK 2.24.0.18
TI compiler 5.1.6

I would like to integrate the dos file system support so I can access files on the SD card. The SDK provide an MMC library and a starterware example. However the starterware examples are not integrated with SYSBIOS and setup the MMU, interrupts, and DMA as though there is no OS present.

Has support for dosfs on this platform been integrated into SYSBIOS?

If not, are there any guides on how be to integrate these starterware examples into SYSBIOS?

Regards,

Brady

Hi Brady,

Unfortunately we don't have a guide on porting starterware application to SYSBIOS. You can refer to the enetlwip examples in the starterware and the ISDK to start with.

Which board are you using?

Hi Brady,

Please go through the SD Bootloader for ICEv2 to get more info on accessing files from SD card. This is a modified version(to work on ICE) of starterware bootloader and you need to port it on SYSBIOS.

Hi Prajith,

I have gone through the SD Bootloader and brought in the starterware DOS support. With the starterware code, I'm able to access the MMC controller's registers. Unfortunately the startware example sets up the interrupts differently than SYSBIOS so I never receive an interrupt indicating the operation is complete.

I'd appreciate some guidence on how best to account for these differences.

Hi Brady,

Are you using SYSBIOS APIs for setting up interrupts . If not please use SYSBIOS APIS instead of starterware APIS.
