[U-Boot] cli_simple_run_command results in an unknown reference to "do_bootd" or "parse_string_outer"
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': | /home/xxxxx/Projects/Yocto/BeagleBoneBlack/build/tmp/work/beaglebone-poky-linux-gnueabi/u-boot/v2015.07+gitAUTOINC+33711bdd4a-r0/git/common/cli.c:43: undefined reference to `parse_string_outer'
Attempting to use the cli_simple_run_command, see below.
/home/xxxxx/Projects/Yocto/BeagleBoneBlack/build/tmp/work/beaglebone-poky-linux-gnueabi/u-boot/v2015.07+gitAUTOINC+33711bdd4a-r0/git/common/command.c:537: undefined reference to `do_bootd' scripts/Makefile.spl:214: recipe for target 'spl/u-boot-spl' failed make[2]: *** [spl/u-boot-spl] Error 1 Makefile:1263: recipe for target 'spl/u-boot-spl' failed make[1]: *** [spl/u-boot-spl] Error 2 Makefile:457: recipe for target '__build_one_by_one' failed make: *** [__build_one_by_one] Error 2
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 ? - Is it possible to use the run_command like this ? - Do I need to configure any special CONFIG to enable this functionality ? - ???

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.
