Updating the Monitor via Tftp | Emerson PMPPC7448 specification

Monitor: Monitor Recovery and Updates

1Issue the following command, where serial_number is the board’s serial number, at the monitor prompt:

PM/PPC-7448 (1.8) => moninit serial_number

If the monitor recovers, skip to step 5. If moninit() fails, continue on to the next step.

2Perform the following tasks: Unprotect the Flash:

PM/PPC-7448 (1.8) => protect off all

Erase the monitor region of soldered Flash:

PM/PPC-7448 (1.8) => erase e8000000 e807ffff

Program the monitor into soldered Flash:

PM/PPC-7448 (1.8) => cp.b fff00000 e8000000 80000

Corrupt the environment variables checksum to force defaults:

PM/PPC-7448 (1.8) => imw 53 1800.2 0 1

3Cycle power to the board.

4Reset the environment parameters. serial_number is the board’s serial number:

PM/PPC-7448 (1.8) => moninit serial_number noburn

If moninit( ) fails, execute the following instruction:

Corrupt the environment variables checksum to force defaults:

PM/PPC-7448 (1.8) => imw 53 1800.2 0 1

5Power down the board and remove the jumper from JP2, pins 1 and 2.

Updating the Monitor via TFTP

To update the monitor, execute the following commands and insert the appropriate data in the italicized fields:

If necessary, edit your network settings:

PM/PPC-7448 (1.8) => setenv ipaddr 192.168.1.100

PM/PPC-7448 (1.8) => setenv gatewayip 192.168.1.1

PM/PPC-7448 (1.8) => setenv netmask 255.255.255.0

PM/PPC-7448 (1.8) => setenv serverip 10.64.16.168

Optionally, save your settings:

PM/PPC-7448 (1.8) => saveenv

TFTP the new monitor (binary) image to memory location 0x100000:

PM/PPC-7448 (1.8) => tftpboot 100000 path_to_file_on_tftp_server

Update the monitor:
