Unresolved symbols from NDK

Bernie Whalen

Other Parts Discussed in Thread: OMAPL138, SYSBIOS, TMS320C6748

I am attempting to add NDK support to an existing application using the procedure from the NDK 2.25 User's Guide however when I build the application there are a number of unresolved symbols (NDK_accept, NDK_bind, etc). I am using BSD sockets. Clearly I need to link to the library containing these routines however I don't know where that may be. I am using Version: 6.1.1.00022 of CCS and the ti-cgt-c6000_8.1.0 compiler.

Here's the error message:

Here's the configuration:

It seems you are using OMAPL138/C6748 platform.
Can you please try to use the NDK examples from NSP package ?
~\ti\nsp_1_10_00_03\packages\ti\ndk\examples

Refer to this e2e post.

The NDK examples also fail to build but for a different reason. Here's the error message:

Please try to install the required SYSBIOS and,XDCtools, and NDK version as given in warning log.

I did get the examples to build successfully by changing the project properties to use the compiler, SYSBIOS and,XDCtools, and NDK versions that I have installed rather than install the older versions referenced in the warning dialog. This, however, does not help me to get my application to build successfully.

I hope you would have included the required BSK include files.
C:\ti\ndk_2_24_03_35\packages\ti\ndk\inc\bsd
Also I would like you to use the NDK example from TI and change the code for the BSD sockets.

I have changed the demo code to use BSD sockets. It builds but does not run. The following is printed to the console:

[C674X_0] Using default MAC address
Using MAC Address: 00-08-ee-03-14-99

It appears that it is stuck at line 986 of csl_emac.c:

while (ECTL_REGS->SOFTRESET != 0x00000000); /* Wait until reset has occured */

I forgot to mention that I am testing this on a TMS320C6748 LCDK development board.

OK this gets even weirder. I was running my BSD example in the debugger and suspended execution after it appeared to be stuck at line 986 of csl_emac.c. At that point I viewed the address 0x1e22004 in the debugger memory browser and found that it was 0x00000000 so I resumed execution and then it appeared to work although it failed to create the socket using the following code:

socket_desc = socket(AF_INET, SOCK_STREAM, 0);

I've solved the latest problem by adding a delay between lines 986 and 987 in csl_emac.c.

ECTL_REGS->SOFTRESET = 0x01;
---> I've added a delay here
while (ECTL_REGS->SOFTRESET != 0x00000000); /* Wait until reset has occured */

The problem with socket() failing was simply me forgetting to include fdOpenSession() and fdCloseSession().

However even with these changes I am unable to ping or connect to the board using the static IP address.

Has anyone ever gotten networking to work with the TMS320C6748 DSP Development Kit?
