Need help with root password reset on FX30

IoT Gateways FX30
21

Still no. No SSH, it still asks for the root password.
I have discovered, that when I’m trying to downgrade to R11 firmware (FX30_WP77xx_full_R11.0.0.007-generic-SWI9X06Y_02.16.06.00.cwe)
the result is

AT!BCFWUPDATESTATUS
!BCFWUPDATESTATUS: FAILED, error code: 80000086
ERROR=Flash write failed: Package not compatible (0X86),STATUS=FAIL

Could you please explain why?
The R15 -
FX30_WP77xx_full_R15.1.0.004-generic-SWI9X06Y_02.36.08.09.cwe
downloaded from the same page here -
https://source.sierrawireless.com/resources/airlink/software_downloads/fx30-firmware/fx30-firmware-catm/#sthash.uuRYTp3A.dpbs
can be flashed successuflly.

it might be because your module is using new memory.
Only the new FW can be downloaded to new memory.
you can check this by:


AT!entercnd="A710"
AT!BSINFO
23

This is the output of “BSINFO” command:

AT!BSINFO

24

yes, this is using new memory

25

I have doubt that my modem was properly reflashed at all.
It has always reported same package version as following:

AT!PACKAGE?
1104770_9910239_FX30(WP7702)_02.36.06.00_00_FX30-Series_001.002_000

even after swiflash’ing it with
FX30_WP77xx_full_R15.1.0.004-generic-SWI9X06Y_02.36.08.09.cwe

So, I have used command “AT!IMAGE” to deleted all firmware images, so it reported all slots empty:

TYPE SLOT STATUS LRU FAILURES UNIQUE_ID   BUILD_ID
FW   1    EMPTY  0   0 0                  
FW   2    EMPTY  0   0 0                  
FW   3    EMPTY  0   0 0                  
Max FW images: 3
Active FW image is at slot 255

and then swiflash following firmware:
FX30_WP77xx_full_R15.1.0.004-generic-SWI9X06Y_02.36.08.09.cwe

After swiflash successfully completed, the firmware is not listed among firmware images:


AT!BCFWUPDATESTATUS
!BCFWUPDATESTATUS: SUCCESS
..

Do you have any ideas why it is not properly reflashed?

26

how about ati3 and ati8?
do they get updated?

27

what do you mean by ati3/ati8 and how to check it?

28

these are AT commands, you can enter it in modem port

OK

According to the release note, you should use fwupdate command to upgrade firmware

31

just to summarize, if I cannot reset root password then I cannot update the modem, is that correct?

32

I can see the yocto and legato are updated

You can try using fdt tool in windows
