Appendix C Firmware Upgrade and Downgrade Procedures

Standard Upgrade and Downgrade Procedures

d.Enter the version command. This command displays the version of the boot code currently stored in Flash memory. This step downloads new firmware into the ASC.

e.Enter the switchcc command to switch to the other ASC.

f.Enter the tftp put <ASC_BT_file> AXIS_ASC_BACKUP.FW command. This step downloads the new boot code into the second ASC.

g.Enter the chkflash command. This command calculates and compares the Flash checksum to verify whether the boot code is correct.

h.Enter the version command. This command displays the version of the boot code currently stored in Flash memory. This step downloads new firmware into the ASC.

i.Enter the tftp put <ASC_FW_file> AXIS_ASC_ACTIVE.FW command.

j.Check the file size of the downloaded firmware. Use this step to check that the firmware was downloaded successfully to the ASC disk.

k.Enter the dspfwrevs command to verify the correct firmware revision.

l.Enter the tftp put <ASC_FW_file> AXIS_ASC_STANDBY.FW command.

m.Check the file size of the downloaded firmware. Use this step to check that the firmware was downloaded successfully to the ASC disk.

n.Enter the dspfwrevs command to verify the correct firmware revision.

Step 4 For all SMs, set the start and end addresses in Flash memory where the boot code file will be written.

a.Enter the flashStartAddr and flashEndAddr commands to start the Flash memory file at Oxbfc00000 and end it at 0xbfc40000

shelf.1.<slot>.<type><as>flashStartAddr = 0xbfc00000 shelf.1.<slot>.<type>.<as>flashEndAddr = 0xbfc40000

b.Enter the tftp put <SM_BT_file> AXIS_SM_1_$slot.FW command.

c.Enter the chkflash command. This command calculates and compares the Flash checksum to verify whether the boot code is correct.

d.Enter the version command. This command displays the version of the boot code currently stored in Flash memory. This step downloads new firmware into the ASC.

Step 5 For all SMs, set the start and end addresses in Flash memory where the firmware file will be written.

a.Enter the flashStartAddr and flashEndAddr commands to start the Flash memory file at Oxbfc40000 and end it at 0xbfd00000

shelf.1.<slot>.<type><as>flashStartAddr = 0xbfc40000 shelf.1.<slot>.<type>.<as>flashEndAddr = 0xbfd00000

b.Enter the tftp put <SM_FW_file> AXIS_SM_1_$slot.FW command.

c.Enter the chkflash command. This command calculates and compares the Flash checksum to verify whether the boot code is correct.

d.Enter the resetsys or clrallcnf command. These commands reset all cards on the shelf.

e.Set the BRAM revision.

f.Enter the dspadrxlat command to ensure that the number of connections is correct.

Step 6 Enter the dsptotals command for all primary and stand-alone SMs.
