6.2. POST
The Power-On-Self-Test (POST) is performed during bootloader booting up. The POST
includes the major devices on the board. The POST result is printed out on the
monitoring port at the end of the bootloader booting. Table 6-2 summarizes the devices
and testing.
(The blade without the NAND flash skips the test;
CONFIG_SYS_POST_NAND_FPGA test
and CONFIG_SYS_POST_NAND_FLASH test.)
Table 6-2 Devices covered by the POST
