Hello all, Im having some issues regarding the usb-rs232 converter (there are some speed incompatibilities because Im giving weird symbols) so I can not get into my mini2440, not even the console. Thats's why I wonder if I can get to ir through ethernet connection, is that possible? how can I achieve that? Thanks!
How are you trying "to get into your mini2440". Via, minicom? Have you set the correct baudrate etc? telnet is a method of talking to your mini2440 via ethernet
Thanks for your reply davef ! The baudrate Im using is the 115200... but it's not working either. I bought my mini2440 since some months ago and I couldn't even test some program coz I can't communicate with it. telnet?? But is the telnet server on from the setup? H ow can I do that??
> But is the telnet server on from the setup? Good question, I don't know. Let's try to get the normal RS232 comms going. Haven't ever done this myself but I think if you connect the RXD and TXD pins together on the RS232 side of your adapter you can perform a "loopback test". I assume you haven't got access to a PC with a RS232 output running either Linux or Windows. (You can try Hyperterm to see if you can talk to the mini2440). Have you got any other USB to RS232 adapters? I know people have had issues with some models of adapters. A search here might turn them up for you. Can you test the adapter on another PC? Good luck!
I had the above shown problems with all PL2303 based adapters i used. This problem persists on any computer i used. After using adapters with the FTDI / FT232RL chipset i got no more noise or garbage when connecting over the serial port. Currently i am using the the Digitus DA-70156 adapter.
Hi Davef, Ive tested it with another cable but the same happened... I bought today a BAFI rs232 USB adapter on the internet so I will need to wait for it. Anyway, the converter that I firstly used is the one which came with the kit, should have worked anyway... Its not a problem on my computer, I know that. I bought it on Industrial ARMWorks, Im a kind of mad at them because of the bad converter they gave to me. Thanks for your reply!
have you considered using ssh via ethernet?
Sean_h, could you please tell me how?? I connected an ethernet cable but there was no light nesr the port, so I guess the ethernet driver is not on yet. How can I achieve that? Thanks
Hi Javier - during the boot process you would see messages relating to the ethernet port. - watch out for a direct connection between PC and Minixxx and crossover cables. Use an ethernet switch (hub) it resolves this problem - ssh x.x.x.x ( from host where x.x.x.x is ip address of target ) - use ifconfig, netstat and nmap for resolving network issues - check your host firewall for opening appropriate port rgds
Hi sean_h... if we are gonna ssh the mini2440, is not a password required?
Hi Javier Yes, you require the root password for the mini2440. On mini2440: ifconfig eth0 If no IP address present: ifconfig eth0 10.0.0.20 (for example) From computer on network: ssh 10.0.0.20 ( and you will get something as follows ) The authenticity of host '10.0.0.20 (10.0.0.20)' can't be established. RSA key fingerprint is 80:c3:f0:48:dd:32:96:0b:84:7b:7a:09:e4:b8:08:e1. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '10.0.0.20' (RSA) to the list of known hosts. root@10.0.0.20's password: Enter the min2440 root password.
