Analysis:
There is no separate document for the GD4 loading procedure.
Follow the below DHCP procedure to flashing new binaryGD4:
Prerequisites :
– CS with patch that supports GD4 (or else, manually create downbin/mg4 folder with the binaries with root permissions – “other” option and manual path selection needed in DHCP Config File option)
– GD4 to be connected on same lan as CS
1. On CS enable DHCP config
- mgr->DHCP Config->R/M
Configuration + DHCP Server
- mgr->DHCP Config->D/H->CPU Main->R/M
Update below fields
Default router address : <router/gw address. e.g. 172.19.11.254>
TFTP Server address : <CS IP e.g. 172.19.11.15>
- mgr->DHCP Config->D/H->CPU Main->Static IP->Create
Update following fields
IP address : 172.19.11.44 ==>GD4 IP@
MAC Address : 00:80:9f:9c:f3:54 ==>GD4 MAC
TFTP Server address : 172.19.11.15 ==> CS IP@
Configuration file + MG4:-/downbin/mg4/binmg4start
2. On GD4 :
Use Ctrl+b Crtl+i to enter uboot menu when prompted with the countdown
Make only one time
U-Boot>> setenv ipaddr 172.19.11.44 ==> GD4 IP
U-Boot>> setenv serverip 172.19.11.15 ==> CS IP
U-Boot>> setenv gatewayip 172.19.11.254 ==> router gateway IP
U-Boot>> setenv netmask 255.255.255.0
U-Boot>> saveenv
U-Boot>> reset
In second time
U-Boot>> ping 172.19.11.1
Redo the above ping test with multiple IPs -router/gateway, CS etc. It will take some seconds till it is alive and the ping succeeds.
U-Boot>> tftpboot /DHS3bin/downbin/mg4/binmg4start
(if tftp NOK redo last command)
U-Boot>> source $loadaddr
Now the download of the binaries will start
Pay attention to the logs –
If you notice a TFTP timeout like this :
<RD_check_sd> assuming boot from ramdisk, so need to fill empty file system
<RD_check_sd> call tftp to get rootfs archive…..
tftp: timeout
then there is a problem on the CS.
We were able to resolve this in our lab as follows :
2 consoles on the CS open – from one we continuously pinged the GD4 IP address; and the other we ran a tcpdump from root
With this the download was successful.
Once completed, the GD4 will reboot and the mcgonfig menu will open up where all parameters need to be initialized fresh.
