Other Parts Discussed in Thread: OMAPL138

I have this

http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/ndk/nsp_1_10_00_03/exports/nsp_1_10_00_03/nsp_1_10_00_03_release_notes.html

And,The example in  nsp_1_10_01_06 .

I want to run the example

(nsp_1_10_01_06\packages\ti\ndk\examples\ndk_evm6748_elf_helloWorld )

on my platform EVMOMAPL137 and CCS 5.2.1 .The example is running on the EVMOMAPL138.

AND,I know I should rebuilt the driver for my C6747

But how to use the driver for C6747,(and I don’t know the meaning of that,it’s some function in c files)

ndk_2_0_0\packages\ti\ndk\src\hal\evmomapl137\eth_omapl137

and the driver for omap138 in

nsp_1_10_01_06\packages\ti\drv\omapl138

to build  driver for EVMOMAPL137 device 

 

THANKS.

    Which version of BIOS are you using? Is it DSP/BIOS 5.x? Or are you using SYS/BIOS 6.x?

    If you are using some DSP/BIOS 5.x version, then you can just link directly against the driver library for the OMAPL137 that's shipped in ndk_2_0_0.

    If you are using SYS/BIOS 6.x, then you can't do this. You must rebuild the driver against SYS/BIOS 6.x.

    What you would need to do is update the OMAPL138 driver with any differences that you see in the OMAPL137 driver (i.e. diff ndk_2_0_0\packages\ti\ndk\src\hal\evmomapl137\eth_omapl137, remove any DSP/BIOS specific API calls (convert them to SYS/BIOS equivalents), update the package name (change all instances of OMAPL138 to OMAPL137) and rebuild it.

    The following thread contains a solution from another community member that has already done this work. Nikolay has attached his port to the thread.
