## Networking Support
|
||||
To make networking support possible a few steps needs to be done on the machine
|
||||
lets assume the following interfaces using ubuntu 18.04 or Fedora 30
|
||||
(the interface names on your machine could be different)
|
||||
```
|
||||
l0: loopback in terface
|
||||
enp0s3: ethernet interface
|
||||
virbr0: virtual bridge (to be created)
|
||||
virbr0-nic: veth virtual interface (to be created)
|
||||
```
|
||||
### A few assumptions (your numbers could varry)
|
||||
```
|
||||
Local Host IP address: 192.168.1.81
|
||||
Local FreeRTOS IP address: 192.168.1.80
|
||||
Local FreeRTOS Subnet mask: 255.255.255.0
|
||||
Default Gateway IP address: 192.168.1.254
|
||||
Default DNS IP address: 192.168.1.254
|
||||
Echo Server IP address: 192.168.1.204
|
||||
Echo Server Port: 7
|
||||
Local FreeRTOS Mac address: 52:54:00:12:34:AD
|
||||
```
|
||||
|
||||
### Building and Running
|
||||
|
||||
1. Fill the defines values in FreeRTOSConfig.h with what is equivalent to the
|
||||
above values on your system
|
||||
```c
|
||||
#define configIP_ADDR0 192
|
||||
#define configIP_ADDR1 168
|
||||
#define configIP_ADDR2 1
|
||||
#define configIP_ADDR3 80
|
||||
|
||||
#define configNET_MASK0 255
|
||||
#define configNET_MASK1 255
|
||||
#define configNET_MASK2 255
|
||||
#define configNET_MASK3 0
|
||||
|
||||
#define configGATEWAY_ADDR0 192
|
||||
#define configGATEWAY_ADDR1 168
|
||||
#define configGATEWAY_ADDR2 1
|
||||
#define configGATEWAY_ADDR3 254
|
||||
|
||||
#define configDNS_SERVER_ADDR0 192
|
||||
#define configDNS_SERVER_ADDR1 168
|
||||
#define configDNS_SERVER_ADDR2 1
|
||||
#define configDNS_SERVER_ADDR3 254
|
||||
|
||||
#define configMAC_ADDR0 0x52
|
||||
#define configMAC_ADDR1 0x54
|
||||
#define configMAC_ADDR2 0x00
|
||||
#define configMAC_ADDR3 0x12
|
||||
#define configMAC_ADDR4 0x34
|
||||
#define configMAC_ADDR5 0xAD
|
||||
|
||||
#define configECHO_SERVER_ADDR0 192
|
||||
#define configECHO_SERVER_ADDR1 168
|
||||
#define configECHO_SERVER_ADDR2 1
|
||||
#define configECHO_SERVER_ADDR3 204
|
||||
```
|
||||
|
||||
2. Build your software
|
||||
```
|
||||
$ make NETWORKING=1
|
||||
```
|
||||
options: DEBUG=1 to build with **-O0** and debugging symbols
|
||||
|
||||
3. On the remote machine (ip 192.168.1.204)
|
||||
```
|
||||
$ sudo nc -l 7
|
||||
```
|
||||
4. Turn off the firewall if running
|
||||
On RedHat/Fedora system (tested Fedora 30) run:
|
||||
```
|
||||
sudo systemctl status firewalld
|
||||
sudo systemctl stop firewalld
|
||||
```
|
||||
On Ubuntu run:
|
||||
```
|
||||
$ sudo ufw disable
|
||||
$ sudo ufw status
|
||||
```
|
||||
5. Setup the local machine
|
||||
Run the fullowing commands replacing the values and interface names
|
||||
that conform to your system
|
||||
```
|
||||
sudo ip link add virbr0 type bridge
|
||||
sudo ip tuntap add dev virbr0-nic mode tap
|
||||
|
||||
sudo ip addr add 192.168.1.81/24 dev virbr0
|
||||
|
||||
sudo brctl addif virbr0 enp0s3
|
||||
sudo brctl addif virbr0 virbr0-nic
|
||||
|
||||
sudo ip link set virbr0 up
|
||||
sudo ip link set virbr0-nic up
|
||||
|
||||
sudo ip route add default via 192.168.1.254 dev virbr0
|
||||
```
|
||||
|
||||
6. Run the demo
|
||||
```
|
||||
$ sudo qemu-system-arm -machine mps2-an385 -cpu cortex-m3
|
||||
-kernel ./build/RTOSDemo.axf \
|
||||
-netdev tap,id=mynet0,ifname=virbr0-nic,script=no \
|
||||
-net nic,macaddr=52:54:00:12:34:AD,model=lan9118,netdev=mynet0 \
|
||||
-object filter-dump,id=tap_dump,netdev=mynet0,file=/tmp/qemu_tap_dump\
|
||||
-display gtk -m 16M -nographic -serial stdio \
|
||||
-monitor null -semihosting -semihosting-config enable=on,target=native
|
||||
```
|
||||
Replace the value of macaddr=52:54:00:12:34:AD with your own value from
|
||||
```
|
||||
configMAC_ADDR0 through configMAC_ADDR5
|
||||
```
|
||||
|
||||
7. Expectations
|
||||
On the remote machine you should expect to see something similar to the
|
||||
following:
|
||||
```
|
||||
$ sudo nc -l 7
|
||||
Password:
|
||||
TxRx message number
|
||||
0FGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~0123456789:;<=> ?
|
||||
@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~0123456789:;<=>?
|
||||
@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~0123456789:;<=>?
|
||||
@ABCDEFGHIJKLM
|
||||
```

||||

||||

2. tcpdump
|

To monitor packets received to quemu running the qemu command (qemu-system-arm)
|

shown above will create a network packet dump that you could inspect with
|
||||

```
|

$ sudo tcpdump -r /tmp/qemu_tap_dump | less
|

|
||||
"blinking" to be repeatedly printed on the screen.
