Hello, I was attempting to create a custom u-boot command. But I am not
able to get the
"run_command" or "cli_simple_run_command" to work.
I`m building u-boot: am335x_boneblack_defconfig
Attempting to use the "run_command" function results in:
| common/built-in.o: In function `run_command':
|

Attempting to use the cli_simple_run_command, see below.

The small test code is added as cmd_mytestcmd.c in the common/ directory
and in the common/Makefile  "obj-y += cmd_mytestcmd.o" is added at the end
of the file.
#include <common.h>
#include <command.h>
#include <cli.h>
#define MAX_CMD_LEN (255)
static int do_mytest(cmd_tbl_t *cmdtp, int flag, int argc, char * const
argv[])
{
        int ret = 0;
        char cmd[MAX_CMD_LEN] = "load mmc 0:1 ${loadaddr} my.env";
        ret = cli_simple_run_command(cmd, 0);
        if (ret == 0) {
            printf("OK\n");
        } else {
            printf("NOK\n");
        }
    return ret;

}
U_BOOT_CMD(
        mytestcmd,      1,      0,      do_mytest,
        "my test command",
        "");
What am I missing here ?
You appear to be adding your command to SPL. This is not supported.
Commands are only available (at present) in U-Boot proper.
...

Is it possible to use the run_command like this ?

...
From U-Boot proper, yes; from SPL, no.
...

Do I need to configure any special CONFIG to enable this functionality ?

Just call the function from outside SPL code.
...

???
