[U-Boot] POST in u-boot for P2020 process

[U-Boot] POST in u-boot for P2020 process

[pshambhu]

Hi,

I am interested in performing POST (Power On Self Test ) operation in
u-boot. As soon as the system starts booting , it should perform some basic
functionality Testing,

- Cache test
- Memory Test
- RAM test
- I2C test
- SPI Test
- Ethernet Test
- UART test
- Watch Dog Timer Test


Please let me know the changes required in U-boot Code to perform POST
operation while System bootup.


Thanks & Regards
Pradeep S

You have to implement the required tests for your hardware (unless
these already exist) and then enable them in your board config file;
please see doc/README.POST for details.

BTW: running these tests always for each and every boot is probably a
very bad idea, as some of these testes are pretty expensive in terms
of time needed.  Also, some may have specific requirements to the
hardware configuration (like there must [or nust not] be network
cable attached, etc.).

Best regards,

Hi Denx,

          Thanks for replying, I have read the document, i have to enable
the POST as well with the macro "CONFIG_POST" and "CONFIG_CMD_DIAG", but i
am getting lot of compilation errors. Am i missing something while
configuring ??   And post.h is also getting generated, which describes the
different types POST operation ( cache test, memory test... etc). All macros
are there in post.h , is there anything which i need to include in
configuration file ??


Thanks 
Pradeep

It's difficult to tell when you do not mention what exactly you
selected / enabled, and when you do not tell us what these "lot of
compilation errors" are exactly (include a log?).

There are completely generic tests, there are SoC specific tests, and
there are board specific tests.  Depending on what you enabled, some
of these tests may ned to be implemented for your configuration.

It appears you failed to define post_word_load(), post_word_store(),
post_hotkeys_pressed(), post_bootmode_get() and post_bootmode_init()
in your board specific code.

Did you read doc/README.POST ?

These appear to be unrelated to me.

By the way: you are aware that v2009.11 is totally outdated?  It makes
not much sense to invest efforts in extending such old code.  Please
do yourself (and us) a favour and update first to recent code.

You have it all at your hands.  Check for example the lwmon / lwmon5
board configurations.
