FreeRTOS_CLIRegisterCommand not working

jren68 — Wed, 24 Oct 2018 00:22:09 GMT

I am following this tutorial and have

1. Implemented a Command

static BaseType_t prvTaskStatsCommand( int8_t *pcWriteBuffer,
size_t xWriteBufferLen,
const int8_t *pcCommandString )
{
( void ) xWriteBufferLen;
return pdFALSE;
}

2. created the mapping

static const CLI_Command_Definition_t xDelCommand =
{
"abc",
"del <filename>: Deletes <filename> from the disk\r\n",
prvTaskStatsCommand,
1
};

3. registered with FreeRTOS+CLI

void vRegisterCLICommands( void )
{
int a = FreeRTOS_CLIRegisterCommand( &xDelCommand );
printf("hello world %i\n", a);
}

I put vRegisterCLICommands() in main and the printout is "hello world 1", indicating the registration is successful.

Then I tried

help abc

in the debug console in MCUXpresso, but abc is not there. This is what I got

Undefined command: "abc". Try "help".

why FreeRTOS_CLIRegisterCommand is not working?

what should I do after register the command with FreeRTOS_CLI?

I figured out what's the problem...the console is the gdb console, not a shell or UART terminal that connects directly to the board...

Thanks for sharing your idea.

most of the board SDK will have a shell demo, that script can be used as a console and one can call the registered functions from the shell successfully.
