Swiflash failure in custom board

IoT Modules WP Series
1

Hi Jyijyi,
I am trying to flash our custom WP7608 board by swiflash command from host. The board has Release 16 binaries. I am getting following errors:

raghavan@raghavan-HP-350-G2:~/wp7608$ sudo swiflash -m “WP76XX” -i custom-firmware.spk
Detecting USB of the target
DONE
Communicating with the target
DONE
Switching to firmware download mode
…ERROR: Failed to enter download mode
raghavan@raghavan-HP-350-G2:~/wp7608$

Could you please tell me the reason for failure?.

how about typing “AT!boothold” before running the swiflash command?
it should be forced to go into download mode.

3

Hi Jyijyi,
I am running below command in WP7608 Linux command line. But i am getting some error:
root@swi-mdm9x28-wp:~# microcom -E /dev/ttyAT
microcom: invalid number ‘/dev/ttyAT’
root@swi-mdm9x28-wp:~#

Thanks,
Raghavan.

How about “microcom /dev/ttyAT”

5

Hi Jyijyi,
The “microcom /dev/ttyAT” command works and “AT!BOOTHOLD” reboots the unit. But swiflash fails to detect the USB port.

raghavan@raghavan-HP-350-G2:~/WP7608 $ swiflash -f -m “WP76XX” -i custom-firmware.spk
Detecting USB of the target
No device connected

Thanks,
Raghavan.

Are you able to find /dev/ttyUSBx on your linux PC after at!boothold ?

Another method is to transfer your spk file to /tmp folder of module by scp command ,and then use “fwupdate download xxx.spk” on module console to update firmware.

7

Hi Jyijyi,
Unfortunately, i programmed a custom binary without legato.cwe. So fwupdate command is not available. How can i recover the board?

No I cannot find any /dev/ttyUSBx on Linux PC after issuing swiflash command or “at!boothold” command. These 2 commands reboot the board. So /dev/ttyUSBx disappears.

Before “at!boothold” in custom board, i can see below line in lsusb in host computer:
Bus 001 Device 033: ID 1199:68c0 Sierra Wireless, Inc.

After “at!boothold” command in custom board “Sierra Wireless” is not appearing in lsusb output in Host computer.

Did you install the GobiSerial driver in linux ?
https://source.sierrawireless.com/resources/airprime/software/usb-drivers-linux-qmi-software-s2,-d-,42n2,-d-,64/#sthash.EVthsMay.dpbs

You can also plug the USB cable to Windows and use the exe to do official FW upgrade

Hi Jyijyi,

Could you please provide link for fwupdate from windows?.

I have compiled GobiSerial driver. Should I install by insmod command?. Even before this GobiSerial driver compilation, i could ping the 192.168.2.2 IP address. My linux PC got 192.168.2.3 ip address automatically after plugging USB cable.

 What is next step after GobiSerial compilation?.

Thanks,
Raghavan.

You need to type “sudo make install” to install the driver

Windows platform is using exe file, not fwupdate

https://source.sierrawireless.com/resources/airprime/software/wp76xx/wp76xx-firmware-release-16/

11

Hi Jyijyi,
I have done following steps:

  1. Connect the board USB in Windows PC. And it is detected as Sierra Wireless
  2. Run WP76xx_Release16_SIERRA exe file
  3. Board is rebooting and stopped at same log messages in previous comments
  4. Board is not detected at this time. So exe file gives error.

Before running exe file, the Windows Device Manager output shows “Sierra Wireless USB Composite Device”

I am getting following output in Windows when I run WP76xx_Release16_SIERRA exe file.

Another way to update module FW is as follows:

  1. download a WP76 FW EXE
  2. use 7zip to extract it
  3. there should be a fdt2.exe inside
  4. there should be xxx.spk file inside
  5. use command prompt to update by “fdt2.exe xxx.spk”
13

Hi Jyijyi,

I ran below command:
fdt2.exe WP76xx_Release16_SIERRA.spk

It failed. I got same logs as previous comment in this thread.

Thanks,
Raghavan.

14

What port do you have in device manager?

15

Hi Jyijyi,

  1. Board is booted upto Linux
  2. Connect USB cable between board and Windows PC.
  3. Device Manager shows “Sierra Wireless USB Composite Device”
  4. In “Terra Term” window, I can see some ports. Only COM3 was there before inserting the USB cable. Our board has separate RS232 port. But that is not connected during this test.

Can you use winscp to transfer the spk file to module /tmp folder?

17

Hi Jyijyi,
Yes, I can do. But fwupdate and related libraries are not available in the board. So fwupdate command will not work.

Thanks,
Raghavan.

18

You can use fwupdate on linux pc

https://docs.legato.io/latest/toolsHost_fwupdate.html

19

Hi Jyijyi,
I cannot find out any fwupdate command in ubuntu 14.04. That command is not appearing in Linux PC even after “sudo apt-get install fwupdate”.

Thanks,
Raghavan.

I did it in “leaf shell”


owner@owner-ThinkPad-X220:~/LEAF/wp77$ leaf shell

Leaf Shell /bin/bash started in Leaf environment.

(lsh:wp77) owner@owner-ThinkPad-X220:~/LEAF/wp77$ fwupdate -h


NAME
    fwupdate - download or query modem firmware

SYNOPSIS
    fwupdate help

    fwupdate install [TARGET_IP]
    fwupdate checkStatus [TARGET_IP]
    fwupdate markGood [TARGET_IP]
    fwupdate download FILE [TARGET_IP]

DESCRIPTION

    fwupdate help
      - Print this help message and exit
    
    fwupdate query [TARGET_IP]
      - Query the current firmware version. This includes the modem firmware version, the
        bootloader version, and the linux kernel version.
        This can be used after a download and modem reset, to confirm the firmware version.
    
    fwupdate downloadOnly FILE [TARGET_IP]
      - Download the given CWE file.
        Waits for another command after a successful download.
    
    fwupdate checkStatus [TARGET_IP]
      - Check the status of the downloaded package (DualSys platform only).
    
    fwupdate install [TARGET_IP]
      - Install the downloaded firmware.
        Single System: Trigger reset to initiate install.
        Dual System: Swap and reset to run the downloaded firmware or go back to the old system
        if the running system is not marked good.
    
    fwupdate markGood [TARGET_IP]
      - Mark good the current system (DualSys platform only).
    
    fwupdate download FILE [TARGET_IP]
      - do download, install and markGood in one time.
        After a successful download, the modem will reset.


ENVIRONMENT

    If the TARGET_IP value is not given and the environment variable DEST_IP
    is set then DEST_IP will be used as TARGET_IP


(lsh:wp77) owner@owner-ThinkPad-X220:~/LEAF/wp77$

BTW, it seems your module really has problem as it cannot FW upgrade through Linux PC and Windows PC…
