Eth0 not coming up
Depending on what the Zynq RJ45 jack is connected to, the autoneg can do some strange things. Please check /fw/startup.sh to see the state of the line
root@zynq_os:~# cat /fw/startup.sh echo Startup script! ethtool -s eth0 speed 100 duplex full autoneg off
Try toggling if the ethtool line is commented out.
IPMC/Zynq BOOT handshaking.
Useful commands for debugging
- SHM is the shelf manager ip
- BLAD_IPMB_ADDR is blade IPMC address 0x9a for physical slot 1
Find blade address
ipmitool -I lanplus -H SHM -P "" fru list
or look at SM webpage
Connect to Zynq via SOL (works by default, IPMC can override destination)
ipmitool -v -I lanplus -H 192.168.20.6 -U "soluser" -P "<PWD>" -C 0 sol activate
Force reset the blade
ipmitool -I lan -H SHM -P "" -t BLADE_IPMB_ADDR mc reset cold
The ZYNQ must write a '1' to SLAVE_I2C.S1.SM.STATUS.DONE If this doesn't happen, the IPMC will shut down the blade.
CentOS upgrades to partition 2 (root) Network:
- Locally extract as root the tarball (tar -zxpf) and then rsync to host
- sudo tar --numeric-owner -p -zcf ../2020-01-29-SD_p2.tar.gz ./
- sudo rsync -P -r -l -p -o -g -W --numeric-ids ./ root@host:/
- sudo rsync -P -r -l -p -o -g -W -c --numeric-ids ./ root@host:/
- sudo rsync -e 'ssh -p tunnel_port' -P -r -l -p -o -g -W -c --numeric-ids ./ root@host:/
IPMC issues
devboard power up:
- SETHA 0x34 - set the hw address so the IPMC can power up
Restart shutdown Blade
First figure out the ipmb address of the blade. One way to do this is via the shelf manager webpage. Since you are probably in a shell, use lynx.
lynx IP
Shelf IP = 192.168.0.171 BU, 192.168.0.2 TIF
To get the info, select Boards/IPMC/AMCs->Boards->Show
Once the page refreshes, go to the bottom and select the board physical slot you want.
Once you submit you'll see a listing with the physical address and the IPMB address
ex:
Physical Slot # 1
9a: Entity: (0xa0, 0x60) Maximum FRU device ID: 0x00
PICMG Version 2.3 Hot Swap State: M4 (Active), Previous: M3 (Activation In Process), Last State Change Cause: Normal State Change (0x0)
9a: FRU # 0
Entity: (0xa0, 0x60) Hot Swap State: M4 (Active), Previous: M3 (Activation In Process), Last State Change Cause: Normal State Change (0x0) Device ID String: "APOLLO-BLADE"
Physical Slot # 1
9a: Entity: (0xa0, 0x60) Maximum FRU device ID: 0x00
PICMG Version 2.3 Hot Swap State: M4 (Active), Previous: M3 (Activation In Process), Last State Change Cause: Normal State Change (0x0)
9a: FRU # 0
Entity: (0xa0, 0x60) Hot Swap State: M4 (Active), Previous: M3 (Activation In Process), Last State Change Cause: Normal State Change (0x0) Device ID String: "APOLLO-BLADE"
Now we can see that physical slot #1 has ipmb address 0x9a and is an Apollo blade
Now we can apply a warm restart with
ipmitool -I lanplus -H SHELF_MAN_IP -P "" -t IPMB_ADDR mc reset warm
ipmitool -I lanplus -H 192.168.0.2 -P "" -t 0x9a mc reset warm

Blade time
Check that you have /dev/rtc0, if you don't, you are probably missing the rt clock battery.
Get time from ntp
ntpdate ntp.server
Set RT clock from system clock
hwclock -w
Read the RT clock
hwclock -r
Network troubles
Use SOL to connect, reset the networking and restart DHCP lease
Using BUTool's IPMISOL plugin, connect to the blade via the IPMC
