11.4 R30
New:
1. The boot block has been modified. Therefore a simple upgrade of the firmware does not
enable all improvements. The old bootblock did not allow to keep the CLI cable connect-
ed during boot. Therefore: Flash the full R30 firmware with the tool lpcFlash then upgrade
R30 (MCH type AM5901 only) to have R30 in both firmware banks.
2. Support of VLAN for the ethernet management port.
3. SOL support for the CLI serial interface via the ethernet management port.
4. The Master Write-Read command is now supported in a unique way by the CLI using the
'tipmi ...' command and the standard IPMI command.
Command parameter 'bus ID' is re-structured in difference to the former implementation:
[7:4] channel number (refer to eI2CIF_Interface in i2cifBoard.h:
= 0 = for bus with carrier's EEPROM etc.
= 1 = for bus with FRU/NVParams etc. EEPROM etc.
= 2 = for bus with Temperature sensors etc.
= 3 = for Inter MCH IPMB bus
= 4 = for IPMB-L
= 5 = for IPMB-A
= 6 = for IPMB-B
Note: channels 3...6 are for master write-read only accessible in test mode. Write with
this command is only supported for channels 1, 3.
For switching the test mode on please refer to the IPMI command 'Manufacturing Test
On' in ipmb.c/IpmManufacturingTestOn().
[3:1] bus ID = 1
[0] bus type = 1
5. Parameters of IPMI command "Manufacturing Test On":
Request data:
[1:4] password = 0xb4 0x90 0x91 0x8b
[5] Mode = 0x80 = Board test. The bits in [6] are valid for the MCH.
[6] Test option bits for to switch off disturbing activities:
Bit 0 = 1 = Standard access to IPMBs is off
Bit 1 = 1 = Standard access to the i2c temperature device is off
Bit 2 = 1 = Standard sensor readings are off
Bit 3 = 1 = No standard MCH device is active (temp. control, power control etc.)
All bits = 0: All kinds of hardware access by the standard firmware is allowed, i.e. the test
mode is completely disabled. Use this to disable the board test again.
