WP8548 Boot issue mbim

mangOH Red
1

Hello,

I have a brand new Mangoh red platform with WP8548 module. I have flashed the generic firmware SWI9X15Y_07.12.09.00 using the swiflash tool.
I cannot connect to the board with ssh with IP 196.168.2.2
If I connect a serial terminal to the board it looks like the boot sequence is stuck.
Here is the message:

The boot is looping with this sequence indefinitely.
Does anybody has a solution to this ?

Thanks for your help.
Olivier.

Yes,
On mine with the latest software for AT&T, (Release 14 page, but software is 13.1)
Just wait a few minutes and you will eventually get a login prompt. It appears that Sierra changed the functionality for security reasons. I’ve had to alternate a chip between a Mangoh Green and the Red about 5 times to get something that works. Mine eventually comes up with a login on the port. I also use a WP7504 not a WP8548. I will try that. I am very new to the RED, but have built quite a bit on the GREEN.

Hi Olivier,

Can you update to the latest firmware and check:

regards,

Hi Ashish,

I have already updated the firmware to the latest version (Release 14) without success.
I have dumped the complete boot log to help analysis.
But I cannot upload the complete log, is there any logs or other information I can send you to help analyzing the issue ?

Thanks,
Olivier.

5

Do you have the USB cable plugged into the CF3 USB port?

6

Mangoh red has two USB connections one for the power and one for serial communication, you can select the one for communication and the one for powering the board. I have tested both configurations and I get the same result each time.

7

Can you try by having both cables connected? Also, can you try do firmware upgrade using swiflash as shown in the video tutorials on a linux machine?

8

Both USB cables are connected, one is used to power up the board and the other one to communicate with the board.
Sorry if it was not clear but I have already flashed the module with swiflash to update to the last firmware.
Here is the Linux version reported during the boot sequence:
Linux version 3.14.29ltsi-961ca71325_ab5094eade

Thanks.

9

can you post the console output during bootup?
also, can you look at this page

Sorry I cannot upload files !
