A.3 M-POST Result

The status of the execution of M-POST can be understood by reading 10th bit of BROM_STATUS located at 0x0000_0002. The details regarding the test execution can be understood from return value of M-POST test function is stored at “0x0000_0008”. The values can be decoded as given in Table 5-2.

Table 5-2 M-POST Status
M-POST Status Return Value
Test not executed 0x00000000
Always fail test timeout error 0xFF00FF00
Always fail test incorrect operation 0xFF11FF00
Test timeout error 0xFF22FF00
Test timeout error 0xFF33FF00
Test fail 0xFF44FF00
Test pass 0xFFFFFFFF
