DM8148 SYS/BIOS questions

acornel

For an upcoming project a customer is interested in running SYS/BIOS on the DM8148 (or similar) micro. I'm aware that the current SYS/BIOS support for the DM8148 is only on the DSP where the ARM core is expected to be running Linux. My question is regarding what might be involved in getting SYS/BIOS working on the ARM core?

I know that there is also a CortexA8 ARM port of SYS/BIOS, so as far as I can tell the SysLink functionality would need to be implemented (or ported?) on the ARM core to get SYS/BIOS working in a minimal fashion (not considering any DM8148 specific peripherals that may not be supported).

Could someone confirm if this assumption is correct?

Second, assuming that my assumption is correct, does anyone know of any materials or documentation that describes this type of effort? I've found information on creating SYS/BIOS drivers, and other various SYS components, but have not found anything solid regarding SysLink yet.

Acornel,

SysLink supports the DM8148 with SYS/BIOS running on the host processor (Cortex-A8). Have a look at the following web site for more information on SysLink. There is also a download link at the to of the page. Our latest release is currently SysLink 2.10.02.17.

http://processors.wiki.ti.com/index.php/Category:SysLink

The install guide section 1.3.3 gives details on how to build SysLink for SYS/BIOS on all processors (including the Cortex-A8) for the TI814X device. I think this is what you are looking for?

Interesting, our understanding was that SYS/BIOS (and therefore SysLink) wasn't supported on the Cortex-A8 core of the DM8148. It's great to hear that isn't the case.

For the DM8148, what sort of support is there for the USB and Ethernet peripherals? If we intend to use SYS/BIOS running on both the ARM and DSP cores, is there some level of USB and TCP/IP(/UDP) stack provided with SYS/BIOS? Or will we need to handle providing those software functions on our own?

For Ethernet, there is the NDK (Networking Development Kit) which runs on SYS/BIOS. Take a look the following link:

http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/ndk/index.html

You'll need the NSP (NDK Support package). This can be found here: http://bangsdowebsvr01.india.ti.com:8090/AV_BIOS_SDK/00_03_00_00/index_FDS.html

Regarding the USB support, we don't currently have a USB driver for SYS/BIOS for the DM8148.

Hi Todd

http://bangsdowebsvr01.india.ti.com:8090/AV_BIOS_SDK/00_03_00_00/index_FDS.html

but the link is dead. Where can I get it today?

I am working with DM8147. I want run SYS/BIOS + NDK on DSP

Thanks

Hi long rainylng,

In order to obtain this SDK, you must request this through your FAE. Please contact your FAE and put in a request for the above SDK.

Hi Steven,

I have been in search of this SDK for a long time , I have contacted Ti distributors but it seems like they do not have a clue about it . Is there any way to get this package ?

Regards
Ammar

Ammar,

Nobody on this forum has access to this NSP, which I think was the gist of Steven's response. You are posting on a very old thread, so the chances of you getting a better response is low. I suggest you start a new thread and post it to the DM8148 E2E forum to see if anyone there has access to this old package.
