DSP BOOTMODE

Other Parts Discussed in Thread: OMAP-L138, OMAPL138

Hi,

I am new to the DSP and DSPLINK. I am confused about the default DSP bootmode. In the component file in the DSPLINK sample application, there is not defined bootmode. So what is the default bootmode? Is it DSP_BootMode_Boot_NoPwr or DSP_BootMode_Boot_Pwr? After the ARM load the DSP executable, do I need to call EVMOMAPL138_init(), EVMOMAPL138_initRAM() and USTIMER_init()?

Thanks in advance!

Ran Pang,

I guess from your post, you are using EVMOMAPL138 board.
Please have a look at the below wiki for various boot mode,
http://processors.wiki.ti.com/index.php/GSG:_OMAP-L138_DVEVM_Additional_Procedures
The OMAP-L138 is an ARM-boot device, an ARM executable must be booted first and wake up the DSP.
For C6748, the DSP AIS binary can be booted directly. Refer the OMAPL138 bootloader guide.

You can find the more details of OMAPL138 from the product page and get the software link as mentioned the below links,

Hi Pubesh,

Thanks for your reply. Yes, I am using OMAPL138 board. But I didn't get you. I don't know where I can find the DSP BOOTMODE setting, when ARM side load and start the DSP executable using DSPLINK. And what kind of initialization have been done, psc, pll, pinmuxes, ram or others? I am new to the embedded system, could you please explain more clear?

Thanks,

Ran
