DSP/BIOS and 16 bit SPI

Norman Wong

Other Parts Discussed in Thread: OMAP-L137, OMAP-L138, OMAPL138

My development enviroment

OMAP-L137
CCS 3.3.81.11
BIOS 5.33.01
PSP 01.30.01
EDMA3 01.11.01.04

The PSP 01.30.01 SPI driver does not work in EDMA mode with 16 bit data. It transfers only the lower 8 bits of every 16 bit word. I have ported over the char width related changes from PSP 2.10.01. It appears to work. Attached are the patched files. Are there any other changes I need to port over? Will there every be a newer version of PSP 1 or a PSP 2 thats supports the OMAP-L137? Also, I believe PSP 2.10 webpage note states support for DA830. Shouldn't that be DA850 to match OMAP-L138 and C6748?

    Hi Norman Wong ,

    The changes which you have made is perfect.

    As you have seen it has been corrected in the latest PSP 2.10.01.

    If you install the 2.10.01 PSP, it has library for C6748 and the OMAPL138 seperately. Along with these, we also support DA830 (which is not OMAPL138/C6748). So, the 2.10.01 version of the BIOS PSP supports DA830 not the DA850.

    DA830 and OMAPL137 both are same, which is why 1.30.01 has the OMAPL137 support and in 2.10.01, it is named as DA830. 

    Thanks and Regards,

    Thanks for confirming my changes. So ...PSP 2.10.01 supports DA830 and requires DSP/BIOS 6.x and CCS4. In the current naming convention, PSP 2.10.01 supports OMAP-L137 and C6747 and requires SYS/BIOS 6.x and CCS4?

    Yes, the PSP 2.10.01 supports OMAPL137 which has both ARM and DSP in it. This PSP requires SYS/BIOS 6.x and CCS4.
