TI-OpenThread 1.07.00 to 1.08.00¶
In this guide we will take the doorlock example application from the
TI-OpenThread Stack version 1.07.00
(4.10 SDK) to work with the
TI-OpenThread Stack version 1.08.00
(4.20 SDK). The doorlock is a
MTD example, the migration will be very similar for FTD
projects. I am showing off migrating a ti-cgt toolchain example (ccs).
Warning
The door_lock example was chosen for its simple nature, and because it shows off the issues we faced porting from the previous stack to this one. This guide is by no means exhaustive, your application may use different APIs or expect different behavior.
Switch Project to New SDK¶
Follow the instructions here to make the current project use the new SDK.
We will resolve issues specific to this migration below.
Updated OpenThread Functions¶
We need to change the function otPlatDiagProcess
(in doorlock.c):
-void otPlatDiagProcess(otInstance *aInstance, int argc, char *argv[],
+otError otPlatDiagProcess(otInstance *aInstance, uint8_t argc, char *argv[],
char *aOutput, size_t aOutputMaxLen)
{
...
+ return retval;
}
Change Library Include Paths¶
Due to new build location for libraries (e.g. libmbedcrypto*, libopenthread*), we need to modify the search paths for them: Right-click project → Properties → Build → ARM Linker → File Search Path. In the library search path section, change the following:
${REF_PROJECT_1_LOC}/Debug
${REF_PROJECT_2_LOC}/Debug
${REF_PROJECT_3_LOC}/Debug
to
${REF_PROJECT_1_LOC}/OptimizeSize
${REF_PROJECT_2_LOC}/OptimizeSize
${REF_PROJECT_3_LOC}/OptimizeSize
