Other Parts Discussed in Thread: TEST2, OMAP-L138

Hello,

we try to read sd card on sys bios, but we can t achieve. i could not find necessary libraries to to start sd card. there is no commands such as "mmcsdPscInit()" mentioned in the document. However there are 3 files in "C:\ti\biospsp_03_01_01_00\drivers" "mcasp,mcbsp,psc". i couldn't see a library for sd.

i have stated my sample project on attachment.

ccs = 5.5

xdctools = 3.25.6.96

biospsp = 3.0.1.00

sys/bios = 6.37.4.32

board = lcdk 6748

Hello Sinan,

- I am not 100% sure but I think that all the SW should be included in the BIOS6_PSP 03_01_01_00
SW package.

In one of those SW package there should be the following folder:
        \packages\ti\pspiom\platforms\evmxxxx\build\evmInit.pjt
see:
     http://e2e.ti.com/support/embedded/tirtos/f/355/t/243302.aspx
     http://e2e.ti.com/support/embedded/tirtos/f/355/p/200485/713523.aspx#713523

Looking at the BIOS6_PSP 03_01_01_00 C6748_BIOSPSP_Userguide.pdf and C6748_BIOSPSP_Datasheet.pdf it could be that the PSP SW was only validated on the LogicPD C6748 EVM and not on the C6748 LCDK.
Beside the LCDK I think that today only the LogicPD OMAP-L138 EVM is still available but the C674x side SW should be able to run on it.

- You could look as well at the below older SW package to see if some LCDK specific low level SW is provided:
BIOS6_PSP 03_00_01_00

bios_c6sdk_02_00_00_00
http://software-dl.ti.com/dsps/dsps_public_sw/c6000/web/bios_c6sdk/latest/index_FDS.html

- Also the below table does give a summary of the different C674x side SW that have been provided over time:
