TMS320F28388D: tcpEchoF2838X example and TI-RTOS

Other Parts Discussed in Thread: C2000WARE, SYSBIOS

Hello there,

I want to explore the tcpEchoF2838X example project to get familiar with TI-RTOS (afaik there are no other RTOS examples for the F2838x). I imported the project into my workspace, and followed the Readme to install the NDK and NS packages, and set the environment variables.

The project builds OK, with 2 warnings though:
#10247-D creating output section ".binit" without a SECTIONS specification
Invalid project path: Include path not found (\packages\ti\posix\ccs).

Bur this project is only for the ARM core. I would expect also a project that needs to run on CPU1 for system configuration at startup. At the end of the Readme it says "When building in Code Composer Studio, the kernel configuration project will be imported along with the example. The kernel configuration project is referenced by the example, so it will be built first.". I suppose that's the CPU1 project I need?

But in my case nothing was imported except the tcpEchoF2838X project itself. Where is this kernel configuration project, and why wouldn't it be imported automatically?

I use CCS 10.1.1.00004,
C2000Ware_3_03_00_00
bios_6_83_00_18
xdctools_3_61_02_27_core
ndk_f2838x_3_61_01_01
ns_2_60_01_06

Thanks and kind regards

I noticed SYS/BIOS was missing from the project's Products (even though SYS/BIOS is present in the CCS products list), so I added it:

At least now the 'Invalid project path' warning is gone.

When I start the debugger CPU1 is suspended and CM4 is running, but doesn't seem to get an IP address from the DHCP server.

Kind regards,
Arjan

So I added the cm_common_config_c82x project, enabled the ETHERNET define, and loaded it into CPU1 when debugging tcpEchoF2838X. Now it appears to be working OK, an IP address was assigned by the DHCP server:

Still wondering about the 'kernel configuration project' that was mentioned in the Readme though. Can you please clarify?

Kind regards,
Arjan

Hi Arjan,

The cm_common_config_c28x project is required to be run on c28x and is not imported automatically. This enables the peripheral clocks and the GPIO ports that are shared by the C28x and CM.

Thanks,

Hi Yashwant,

That's clear to me now, thanks. But then what is the 'kernel configuration project' that was mentioned in the Readme? Is that the tcpecho.cfg file for SYS/BIOS configuration?

Also, the /src folder (containing sysbios makefiles and libs) in Project Explorer is excluded from build, is that correct?

I'm new to TI C2000 and still learning about SYS/BIOS and CCS, so forgive me if I'm asking silly questions!

Kind regards,
Arjan

Arjan,

Yes, I would agree that it is referring to the BIOS tcpecho.cfg file.

From my understanding of the project, that src folder looks to be intentionally excluded.

Best regards

Chris
