MC7354 hangs on startup after firmware change

IoT Modules MC/EM Series
1

Dear Forum,

I recently purchased two MC7354 modules programmed for use with Verizon. To make a long story short I now need them on AT&T’s network, which means updating the firmware. I downloaded the latest version “Build4544-Approved-7354-EXE” and ran the AT&T program within. The program took about a minute and a half to execute, after which it said the firmware flash was successful. At this point Skylite opened up and showed option to turn the radio on. It is now hung up on processing and I notice that the firmware version still appears to be VZW, any ideas as to how this might have happened

Hi,

Can you open a terminal program to the unit and send the below.

ati

First and foremost thank you for taking time out to help. I currently have the unit connected to my desktop and I am in ubuntu. When I try and use screen on the any of the dev/ttyUSB ports associated with the device i just end up on a black terminal screen i cannot type anything into. i have ensured i am accessing the right ports and that i am using the correct baud rate, 57600. If I am doing something silly here that is keeping me from accing the card I am sorry for my ignorance. I have libqmi on my computer and I was able to see the card using

sudo qmicli -d /dev/cdc-wdm1 --wda-get-data-format
[/dev/cdc-wdm1] Successfully got data format
                   QoS flow header: no
               Link layer protocol: 'raw-ip'
  Uplink data aggregation protocol: 'disabled'
Downlink data aggregation protocol: 'disabled'
                     NDP signature: '0'
  Uplink data aggregation max size: '0'
Downlink data aggregation max size: '0'

however past that I am still stuck. Any advice on what to do next?

Hi,

From your terminal can you send the following commands

ls /dev
lsusb
lsmod
modinfo GobiSerial
modinfo GobiNet

Hi,

From the responses the port to connect to is either going to be /dev/ttyUSB2 or /dev/ttyUSB4, the baud rate does not matter as USB should take care of it although set it to 115200 as a precaution.

Use of qmi_wwan and qcserial can cause issues but you should get further than this.

Regards

Good Afternoon,

Thanks for the information, you were right, it was on ttyUSB4. I will include the code below you requested, however, my inputs do not appear when I type them into the terminal window. Only the outputs.

Ok so the fact you cannot see the commands being typed is because local echo is off, if you want to see them then send

ate1

The reason the unit is no doing anything is because it is in low power mode because of a PRI/firmware mis match as can be seen in

GOBIIM:1

It has the AT&T PRI file on it, it is just not using it, you should be able switch to t using something like the below.
