Re: Which OS for SDR
Already read or badly read.....
If no DHCP offer it falls back on static ip address set into dhcpd.conf
But how to stop RP to act as dhcp client, thus surely use a satic ip ?
Unfortunately each linux distro has its own or tens of new different methods to manage network interfaces....

Re: Which OS for SDR
I think configuring eth0 similarly to lo and wlan0 should do the trick. Maybe adding gateway and DNS addresses would also be needed:What's the method (on your version) to switch to eth0 static ip address ?
Code: Select all
interface eth0
static ip_address=192.168.1.100/24
static routers=192.168.1.1
static domain_name_servers=192.168.1.1
https://www.mankier.com/5/dhcpcd.conf
However, I think a better approach would be to configure the fixed IP address of the Red Pitaya board on the DHCP server or router in your local network.

Re: Which OS for SDR
dhcpcd.conf has no direct eth0 configuration, rather a fallback to profile in case dhcp lease fails:
# Fallback to static profile on eth0.
interface eth0
fallback static_eth0
# Define static profile for eth0.
profile static_eth0
static ip_address=192.168.1.100/24
static routers=192.168.1.1
static domain_name_servers=192.168.1.1
so I think this modifications should work :
# Fallback to static profile on eth0.
#interface eth0 #######commented out
#fallback static_eth0 #######commented out
# Define eth0.
interface eth0
static ip_address=192.168.1.100/24
static routers=192.168.1.1
static domain_name_servers=192.168.1.1
the problem is once rebooted, any modification is lost (included root passwd) like a new os is unpacked from sdcard
Should I perhaps modify the /etc/dhcpcd.conf into sdcard red-pitaya.apkovl.tar.gz ??
# Fallback to static profile on eth0.
interface eth0
fallback static_eth0
# Define static profile for eth0.
profile static_eth0
static ip_address=192.168.1.100/24
static routers=192.168.1.1
static domain_name_servers=192.168.1.1

Yes, for now I'm using a dhcp reservation on my router....However, I think a better approach would be to configure the fixed IP address of the Red Pitaya board on the DHCP server or router in your local network.

Here is the command that saves the configuration changes to SD card:the problem is once rebooted, any modification is lost (included root passwd) like a new os is unpacked from sdcard

Re: Which OS for SDR
How can I enable/assign RX2 to second input of RP ?
If I enable RX2 on PowerSDR, I receive the same signal on both RX despite input2 is disconnected....

Re: Which OS for SDR
I think I have to modify start.sh isn't it ?
In particular from what I understood :
ip link add mvl0 link eth0 address $address type macvlan mode passthru
$apps_dir/sdr_receiver_hpsdr_122_88/sdr-receiver-hpsdr eth0 1 2 1 1 1 1 1 1 &
$apps_dir/sdr_receiver_hpsdr_122_88/sdr-receiver-hpsdr mvl0 1 2 1 1 1 1 1 1 &
What's the real function of those 8 bits ?
And what is mvl0 ? (P.S: edit: ah MACVLAN.....something else to learn to.... )
Thank you for your patience.

Re: Which OS for SDR
Yes, the inputs can be selected by modifying start.sh.
The eight digits are input selectors for eight receivers. 1 corresponds to IN1 and 2 corresponds to IN2.
Alternatively, it could be easier to use the SDR transceiver compatible with HPSDR where the first two receivers are by default connected to two different inputs.

Re: Which OS for SDR
The receivers are not part of OS. They are part of some of the multiple applications.
I provide two applications compatible with the HPSDR protocol:
In SDR transceiver compatible with HPSDR, 2 receivers are directly controlled by the radio operator and 3 are used for diversity reception and amplifier linearization.
I provide two applications compatible with the HPSDR protocol:
- SDR receiver compatible with HPSDR: it has 16 receivers and it is designed for use with CW Skimmer Server and Reverse Beacon Network Aggregator
- SDR transceiver compatible with HPSDR: it has 5 receivers and it is designed for use with PowerSDR mRX PS and Thetis.
