ELFloader and shell command 'exec' example for MB851 (STM32W) platform
|
||||
-----------------------------------------------------------
|
||||
|
||||
Compiles the Contiki hello-world application as a Contiki executable (.ce).
|
||||
The Contiki executable is then uploaded to the MB851 platform via serial, and
|
||||
is stored in the filesystem.
|
||||
Finally, the executable is loaded via the shell command 'exec'.
|
||||
|
||||
NOTE:
|
||||
You may have to reduce the ELF loader memory usage (/platform/sky/contiki-conf.h).
|
||||
Since hello-world uses very little memory:
|
||||
#define ELFLOADER_CONF_DATAMEMORY_SIZE 0x100
|
||||
#define ELFLOADER_CONF_TEXTMEMORY_SIZE 0x100
|
||||
|
||||
|
||||
1. Upload Sky shell with 'exec' command and symbols (requires several recompilations to generate correct symbols):
|
||||
> make
|
||||
> make CORE=shell-exec-test.mb851
|
||||
> make shell-exec-test.flash CORE=shell-exec-test.mb851 PORT=AUTO
|
||||
|
||||
|
||||
2. Verify access to the shell and the filesystem:
|
||||
> make login DEV=/dev/comX
|
||||
SHELL> echo hello shell
|
||||
SHELL> echo test | write mytest.txt
|
||||
SHELL> ls
|
||||
SHELL> read mytest.txt
|
||||
[CTRL-C] to exit the shell
|
||||
|
||||
|
||||
3. Upload Contiki executable hello-world.ce:
|
||||
> make upload-executable DEV=/dev/comX
|
||||
[CTRL-C] to exit the shell when the entire file has been uploaded (after ~30 sec)
|
||||
|
||||
|
||||
4. Verify that hello-world.ce exists in CFS:
|
||||
> make login DEV=/dev/comX
|
||||
SHELL> ls
|
||||
SHELL> read hello-world.ce | size
|
||||
The last command output should equal the size of hello-world.ce in this directory!
|
||||
|
||||
|
||||
5. Load and start hello world:
|
||||
SHELL> exec hello-world.ce
|
||||
The program should now start: the output 'Hello, World' appears.
