=== 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.

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
