[U-Boot] U-boot initialization test

[eija_flight]

Hello,

Below is my board initialization process :

U-Boot 1.3.1 (Nov 27 2008 - 08:30:43) MPC83XX

Reset Status: Software Hard, External/Internal Soft, External/Internal Hard

CPU:   e300c1, MPC8349E, Rev: 31 at 528 MHz, CSB:  264 MHz
Board: MPX8349GC
PCI1:  32 bit, 33 MHz
SRAM:   1 MB
I2C:   ready
DRAM:  512 MB (DDR2, 64-bit, ECC on)
FLASH: 16 MB
PCI:   Bus Dev VenId DevId Class Int
        00  0f  10cf  202b  0380  00
In:    serial
Out:   serial
Err:   serial
Net:   TSEC0, TSEC1

During above initialization process of u-boot, 

1. Does it conduct a test to all board hardware listed?
2. If above answer is yes, what method is used to do the test?

No. In general, there is no testing performed. Minor exceptions from
this rule exist, for example the RAM auto-sizing code also performas a
minimal non-destructive memory test, but this is not strong enough to
be called serious testing.

If you need real Power-On Self Tests (POST), then you must enable
POST in your board configuration and configure it according to your
needs.

If you need such tests, then use the code in post/, see doc/README.POST


Best regards,

I've read through the README.post, and I can see that there's many
implemented test feature built in U-boot. I find it very useful. 

Using U-boot 1.3.1 version,  It is possible (as a user) to apply all of
these test feature into a standalone applications?
because I need to log the result using standalone app. 

Regards,
Eija_flight

U-Boot 1.3.1 is very old and basicly unsupported here. Please use
current code.

POST results get logged in the log buffer (of course you need log
buffer support). You probably can extend the standalone application
interface to access the log buffer, but I'm not sure if this makes
sense. Why not just using the existing U-Boot facilities? Or pass the
log buffer to Linux (see shared log buffer feature in Linux) and
process it therer using standard syslog technology?
