Front Uart Control, Crisis Recovery | Emerson MVME2500 manual

Functional Description

The MVME2500 supports automatic switch over. If booting one device is not successful, the watchdog will trigger the board reset and it will automatically boot on the other device.

4.6.4Crisis Recovery

The MVME2500 provides an independent boot firmware recovery mechanism for the operating system. The firmware recovery can be performed without leaving the firmware environment.

During crisis recovery, the healthy boot image contained in SPI Device B is copied to SPI Device A, replacing the corrupt boot image contained in SPI Device A.

Crisis recovery is performed as follows:

1.Power off the board.

2.Set Switch S2-2 to "ON" to point to SPI Device B (crisis image).

3.Power on the board.

4.Press "h" on the keyboard to go to the U-Boot prompt.

5.Type "moninit fru" to copy the crisis image to SPI Device A.

6.Once the U-Boot prompt is visible, power off the board.

7.Set the S2-3 back to "OFF" to point to the SPI Device A.

8.Power on the board to boot from the newly recovered image on the SPI Device A.

The board will automatically switch over if one of the devices is corrupted.

4.7Front UART Control

The MVME2500 utilizes one of the two UART functions provided in the male micro-mini DB-9 front panel. A male-to-male micro-mini DB-9 to DB9 adapter cable is available under Emerson Part Number SERIAL-MINI-D (30-W2400E01A) and is approximately 12 inches in length.
