Reg SYS/BIOS driver

Other Parts Discussed in Thread: OMAPL138

Hi,

I want to enable EDMA for SDRAM memory to memory transfer.
I could do this without SYS/BIOS by configuring all the registers.
I want to do same thing on SYS/BIOS. Is there any simple way of doing this (ie EDMA_init, EDMA_StartTx)?
I see different things like PSP drivers, EDMA3 LLD etc., And the procedure looks so complex.

Also please le me know if there is a step by step procedure to write a driver on SYS/BIOS.

Other details: Platform - OMAPL138, CCS - v4

thanks, Durga

Please visit the link http://software-dl.ti.com/dsps/dsps_public_sw/sdo_tii/psp/edma3_lld/index.html , and download latest BIOS 6 EDMA. This package has some of the example for memory to memory test.

If you refer to the EDMA examples, then you will easily come to know the EDMA API usage.

Download the sys/bios package and refer the user guide available in the package to understand the different features available in the sys/bios.

Thanks and Regards,
