Hi,

iam planning on reading data from gpmc and store it in usb pendrive using fat 32 file system

the data from the gpmc is so high iam planning on using GPMC on Core 0 and USB host on Core 1

i have enabled Gpmc on Sysbios for A15 dual core but i cant make it to work for USB host

Ive tried using USB host 2.0 alone and i have tested using example it works

but when i enable SMP it is not working ,it does not detect pendrive

Has any one tried working with usb 2.0 HOST smp ,It will be helpfull

Ramachandran,

Unfortunately SMP bios is no longer supported in our RTOS SDK for several years so I do not know of anyone having tried it locally.

I did find the following thread that seems like it might have what you need:

Best,

The project is getting build without any error but it is not detecting the pendrive

Ramachandran,

Please use the existing thread above as collateral. Unfortunately since this is not supported any longer, we cannot validate nor test SMP Bios (TI-RTOS).

Best,

i solved my issue by changing the Usbosaldelay() function into Task_sleep() ,then my usb on smp worked
