3. On ShM A, upgrade U-Boot, Kernel, and DTB on the inactive bank using fcu.
fcu -vuf /usr/local/sam1411-cpu.fri
fcu -vuf /usr/local/sam1411-dtb.fri
fcu -vuf /usr/local/sam1411-kernel.fri
4. On ShM A, check the currently marked boot bank.
fcu -q -d atca-sam1411-cpu
5. On ShM A, swap boot banks to allow for ramdisk upgrade. Choose A or B based on the
result of the previous step.
fcu --mark --bank=<A|B> --device=atca-sam1411-cpu
6. On ShM A, program the ramdisk:
flashcp -v /usr/local/ramdisk.image.gz /dev/mtd4
7. There may be changes to files normally stored in the persistent file area when upgrading.
Refer to the ATCA-SAM1411 Release Notes for more information. If there are no files in the
persistent file area that need to be saved across a reboot (that is, user specific files or
changes to configuration files), the persistent file area can be cleared later (before
rebooting the Shelf Manager).
8. Run fcu on ShM B to upgrade ShM As IPMI FW. Use IPMB address 0x10 for the Shelf
Manager in the left slot and 0x12 for the right slot.
fcu
-t 0x<10|12> -uvf /root/ATCA_sam1411-upgrade-<version>.hex
9. After upgrade, ShM A does not reboot. If this is the second time through the upgrade
procedure, and both ShMs are upgraded, skip to Step 12 .
10. From ShM B, switchover the Shelf Managers:
sv_deactivate
11. Repeat the above process to upgrade the other Shelf Manager and then continue to the
next step.
12. After upgrade, clean out the upgrade files from both the Shelf Managers.
rm /root/ATCA_sam1411-upgrade-<version>.hex
rm /usr/local/sam1411-cpu.fri
rm /usr/local/sam1411-dtb.fri
rm /usr/local/sam1411-kernel.fri
