Hi,

I used the TFTP server proposed on the “Flashing mLinux Firmware” page of Multitech Developer Resources, called tftpd32.

About the configuration of it, I followed the following tutorial : http://www.tricksguide.com/how-to-setup-a-tftp-server-tftpd32-windows.html

With this configuration, the error described in post #10754 occured : firmware files can not be copy from the tftp server because they are too heavy.
To fix this, I unchecked the checkbox called “Option negociation”

Regards,

Tom.

Alright,

Problem fixed, topic close !
My MultiConnect is re-flashed and works just as when I started with it.

I was unable to copy the files because I checked the checkbox “Option negociation” on TFTP server settings.

Thank you for all your support.

Best Regards,

Tom.

Hi Jeff,

Okay, I have another problem now, I can not get the files oe_uImage.bin and oe_rootfs.jffs2 from my PC because they are to heavy.
I obtain the following log => TFTP error: ‘Undefined error code’ (0)

I tried with a lighter file (.txt) and it works, I can copy the .txt file from my PC, but not the firmware files.

I think I am very close

Edit : And now after trying this, I can not boot it anymore even with “env defaut -a” and then “save env”, returning this error :

Loading from nand0, offset 0x200000
** Unknown image type
Wrong Image Format for bootm command
ERROR: can't get kernel image!

Jeff,

Thanks for the tips.

However, I can’t set up the U-boot environment with the minicom, with this command line :

minicom --script=uboot-setenv

The script is running from “setting U-Boot variables…” to “printenv”, then I quit the minicom

So I reboot, interrupt U-Boot, and printenv, but it is still the same environment (with no krb, tftp_kernel and tftp_rootfs)

I tried to setenv manually but errors occurs (syntax error, unknown command ‘nand erase.part bootstarp’)

I think understand that I have to run the uboot-setenv script from U-Boot> but I don’t know how, minicom is not working there.

Hi again,

I tried the debug mode (micro USB connection in the front of the conduit) and this line appears after boot :

jffs2: notice: (186) check_node_data: wrong data CRC in data node at 0x0883dec8: read 0x103ae9f2, calculated 0xb69d3c7e.

So it seems the flash went wrong

Also, I will try to do the U-Boot TFTP to flash the firmware, but I am not sure about the TFTP. All I have to do is put the oe_uImage.bin and oe_rootfs.jffs2 files in the tftpboot dir (c:\tftpboot ?) and configure the ip adresses ?

[Tom Ooten]

Hi Jeff,

Your point is interesting, I checked both files I have download with the md5sums.text file ans it match, so I suppose the files were not corrupted.
Then I tried to re-flash the conduit with the exact same process than I did last time, but when I reboot the conduit nothing happen (the LEDs do not blink in a progression pattern), even with a SD card

Hi again,

The logs on the messages i posted are output from the multitech mlinux model after auto-flashing it with the followed instructions : http://www.multitech.net/developer/software/mlinux/using-mlinux/flashing-mlinux-firmware-for-conduit/ (section “Using Auto-Flash During Reboot”)

To do this I took the following files from the library http://www.multitech.net/mlinux/images/3.1.0/mtcdt/ :

– mlinux-factory-image-mtcdt-20150527081222.rootfs.jffs2
– uImage–3.12.27-r11.2-mtcdt-20150527052826.bin

Should I try using other files for the auto-flash or are those two files okay ?

Tom.

[Tom Ooten]

It seems “/etc/init.d/sshd restart” is doing nothing, no logs on “/var/log/messages” either

sshd is not working

I am off for today, restarting tomorrow on the issue

Thanks a lot to both of you

Tom.

Jeff,

Nothing particular on the log messages, exept from errors about jffs2 :

Plus I have this log :

Also, when I ping google, the output is : Network is unreachable

Hi Jeff,

Thanks for the reply.

The output I showed on post #10429 was from “netstat -na”, there is nothing more that is displayed

I wonder if I did well while flashing the Multiconnect, it seems that the mLinux distribution is not the same as before

Indeed, it seems that the TCP is not configurated or something like that

I know about the gateway definition for connecting on my network subnet, already did it thank you 🙂

[Tom Ooten]

Thank you for the support jason, I can now access the gateway via USB.

But I am still not able to connect via ssh, and here is my /etc/network/interfaces file :

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
auto lo
iface lo inet loopback

# Wired interface
auto eth0

iface eth0 inet static
address 192.168.2.1
netmask 255.255.255.0

# Bridge interface with eth0 (comment out eth0 lines above to use with bridge)
# iface eth0 inet manual
#
# auto br0
# iface br0 inet static
# bridge_ports eth0
# address 192.168.2.1
# netmask 255.255.255.0

# Wifi client
# NOTE: udev rules will bring up wlan0 automatically if a wifi device is detected
# and the wlan0 interface is defined, therefore an "auto wlan0" line is not needed.
# If "auto wlan0" is also specified, startup conflicts may result.
#iface wlan0 inet dhcp
#wpa-conf /var/config/wpa_supplicant.conf
#wpa-driver nl80211

I still have a “ssh: connect to host 192.168.2.1 port 22: Connection refused” when I connect with my PC via ethernet
