PROCESSOR-SDK-C6748: using stdio.h function fopen with fatfs from PDK

Hi! The subject owner is currently out of the office. Please allow a couple of days for a response. Thanks.

Hello,

Sorry, but TI has stopped supporting TI-RTOS (SYSBIOS) based SW development for C6748. Please refer to this announcement and find consolidated resources there.

Regards,

that's super

let's assume i asked about FATFS on a supported processor, then, i'm sure they would have a similar setup and the answer should be the same

We've generally stopped supporting SYSBIOS (TI-RTOS) based SW development for all devices.

so if the answer isn't out there already i'm out of luck

The only other thing that I can think of is the FATFS API documentation at: <pdk_installation_folder>\packages\ti\fs\fatfs\docs\doxygen\html

i did a search in the directory for fopen and stdio and found nothing helpful. an example exists for the old sysbios directory but not in the PDK one. online it looks like you need some kind of wrapper which must have existed when it was a part of sysbios but was taken away when it went to the PDK.

i guess i can try to bring the old sysbios fatfs into the current sysbios and rebuild it and see if that works. i will be using the old fatfs and i will still need the old edma drivers and the old PSP drivers but at least i will have the latest sysbios

I agree that's something you can try.

the old PSP drivers, which try to create a semaphore, aborts when doing a semaphore create. so something must be incompatible with that system. it doesn't look like it will work
