[U-Boot-Users] testing hardware

[Ram]

Hi,
   I would like test my hardware (arm926ejs). One way of doing it is
having a POST
   tests which are part of u-boot code and executed everytime it is powered on.

   am thinking of something like a  client-server.

   client is located on a PC with GUI and allows the user to execute
the specific test.

   The server - which could be part of u-boot or which is downloaed by
u-boot and launched (into  RAM) waits for command from the client. It
executes the command and relays back the results    which is then
stored in the database by the client.



  Can this be in done in u-boot. if i want to use u-boot what changes
do u think i need to do?.


  Please Advice,


Regards,
sriram

Yes, this can be done. The client just has to generate commands for the
U-Boot command line. Unfortunately this means that the client also must
have access to the serial console port.

If you only want a network connection between client und target, you
either have to use netnonsole (doc/README.NetConsole) or write your own
application. Probably you would like to use U-Boot's netconsole code
as a reference implementation.

Keep in mind that U-Boot is not a multi-tasking OS so it is not possible
to let such a test server run in the backgroud. U-Boot doesn't use
interrupts (on most platforms).

With best regards

Hi,
Thanks for your response.


I understand from you that we can download an image onto some location
and execute that image.

can that image (or executable) is using the serial/ethernet? and act
as a iterative server.

and once the end of all commands is sent will the u-boot get the control?.


Please advice,

You can either boot an OS (or some other application),  where  "boot"
means  that the only way back into U-Boot is through a systemn reset;
or you can load and start a "standalone application",  which  returns
to U-Boot after execution.

Yes, it can (depending on the exported U-Boot functions). See the docs.

Define "iterative server"!

In case of  a  stndalone  application:  yes  (unless  you  crash  the
system).
