Re: [ts-7000] Re: 2.6 kernel on ts-7300

Ian,

I imaged my 2GB and 512MB (just in case it mattered) cards with the lenny-eabi image.  Just like in your case JP-2 and JP-6 are jumpered.  I put in the card and boot up.  Once it gets to the prompt menu, I cannot type anything (like exit to proceed with the boot).  If I use the 2.4 image then login over serial works fine. 

I have exactly the same problem with the 2.6.29 that I cross compiled myself.  I can do 'echo "hello" > /dev/ttyAM0', and I will see the output in 'cu' on my laptop. (I can login via SSH into the board).  However, if I try to type anything into the terminal, nothing happens.  If I try to do 'echo "hello" > /dev/ttyUSB0' on my laptop, then the call just hangs and I have to Ctrl-C it.  The same thing happens on my Linux server when using /dev/ttyS0. 

Everything else seems to work except for the 64Megs of RAM being ignored (the board has 128MB).  NFSroot and SD card work fine, and I don't care about X.  I cross compiled load_ts7300 and loaded the ts7300_cyclone2.rbf (i have not double checked that it actually works yet).  Also the UARTs are recognized.

Can you send me your entire dmesg output?  I am curious what messages you see.  Maybe that will give me some clue...

Roman

I take a 512M SD card and ..

dd if=512mbsd-7400- linux2629- lenny-eabi. dd of=/dev/sdb
on my Linux PC.

I put this into my TS-7300 with JP2 and JP6 jumpered and boot. It goes to the "Type 'tshelp' for help" prompt.

I type "exit" and it boots from the SD card.

I have to move S12udev in rcS.d to S03udev to get the ethernet port to come up properly, and I have to "apt-get install nfs-common" for nfs.

The "load_ts7300" code isn't on this image but gcc is, so I compile all required code from an nfs mounted disk.

I imagine X support will need to be pulled from an earlier image.

regards
Ian T.

When I run 'echo "test" > /dev/ttyAM0' on the board, I see the output on the cu terminal of the host computer. (I can SSH into the board to run the commands). If I type a bunch of characters into the serial terminal and then reboot the board, I will see them appear on the fastboot prompt. It is as if the data is not pulled from the host computer and just sits there in the buffer.
