5.8 Power-On Self Test
When the ATCA-F125 is booted, U-boot executes a series of Power-On Self test (POST)
routines. These routines check the functionality of different controllers and other on-board
resources. The result is stored in memory and has the following format.
Information about the POST status can also be obtained by reading the SYS FW PROGRESS IPMI
sensor. Depending on the POST status, the sensor holds the following values.
Table 5-3 POST Result Format
Offset Description
0x0 Magic word: 0xAA55FCE0
0x4 CRC32 checksum over the POST result string
0x8 POST result string. This is a zero-terminated string based on the
following XML-like
syntax:[[Error_description]*]*
tag
identifies the device that was tested. If no POST error was
detected, then the closing tag follows
immediately after the opening tag.

corresponding tag. Note that the tags can be nested, if for
