Cannot connect via network or usb - hardware trouble?
Posted: Mon Oct 13, 2014 9:00 pm
After three months of inactivity, I am trying to start using my red pitaya again, but no success
- When I enter my redpitaya's mac address on the redpitaya website, the ip address reported is 192.168.0.95, but when I point my browser there, it reports "Unable to connect"
- My router's client list does not include the ip or mac address
- "ping 192.168.0.95" reports "Destination Host Unreachable"
- The trouble is not with the network cable: when I connect a laptop to the same cable, it works correctly.
- On the red pitaya's ethernet plug, a yellow led on the right is blinking, but the led on the left remains off.
My conclusion: the ethernet connection is not working properly.
I downloaded the latest version of the software from the red pitaya website and copied it to my SD card, but no change.
To debug, I tried to connect over USB. (My host computer is a linux desktop)
- "lsusb" lists my redpitaya:
Bus 001 Device 024: ID 0403:6015 Future Technology Devices International, Ltd Bridge(I2C/SPI/UART/FIFO)
- The device /dev:ttyUSB0 appears
- "sudo minicom -D /dev/ttyUSB0" starts normally, but I get no prompt from the red pitaya, and no reaction to whatever I type. From time to time, weird characters appear in the minicom terminal.
Should I somehow tell minicom what communication parameters (baud rate, parity, ...) it should use?
When I power the red pitaya, a blue and green led to the side of the ethernet connector are on, and a yellow led is blinking; this all seems normal to me.
Is there anything else I can try, or should I conclude that there is a hardware problem with my red pitaya?
