STWIN.box Wi-Fi Module FW Upgrade - EMW3080

[josejohn]

Hello 

I tried to upgrade the STWIN.box Wi-Fi Module with the instructions provided in the  STM32CubeFunctionPack_DATALOG2_V3.1.0. 

i tried dragging the HEX file to tera term with the following settings attached in the images below. i was not able to successfully upgrade the wifi module.
i am using the stlink-v3minie with the board
i really appreciate the help of community members

kind regards

Hello @josejohn 

From the screenshots you shared, it seems you're not selecting the right COM port.

Once you link STWIN.box + STLINK to the PC, you should select the STLINK COM port named STMicroelectronics STLink Virtual COM Port, as in the above figure: 

Can you double check, use the proper port, and confirm me that the Wi-Fi firmware update procedure goes properly?

Best regards,

Simone

Thank you so much @SimonePradolini for looking into this matter. i still wasn't able to solve the problem. i have uploaded pictures of the same, the settings which are in my PC. i tried dragging the hex file to TeraTerm.  It can be seen that file is being transferred at a very low speed. i tried doing it multiple times. but the transfer was never ending.

 

 

 

could you please look into this.

Apart from the above images attached these are the other images of the settings, as only 3 images are allowed to upload in a post.

Hello @josejohn 

The hex file is a binary you must flash onto the STWIN.box core system. To do so, you can:

• flash the board by using STM32CubeProgrammer
  
• drag-and-drop the hex file to the STLINK via file explorer
  

Once the new firmware is uploaded, then you'll see the expected output on the terminal console and then you can upgrade the Wi-Fi module.

The procedure related to Tera Term isn’t related to the flashing of the hex file. I'm sorry if the README file wasn’t clear. I'll upgrade it soon with some more specific guidelines.

Best regards,

Simone

Thank you @SimonePradolini  for your detailed reply. i tried flashing the HEX file with STM32 programmer and it says download was successful. but after that the device was not be able to connect to my phone app. the GREEN LED was was not blinking but it was in a on state..
In the second image you shared i can't find the device STLNIK_V3M under My PC to drag and drop. I'm using STLINK_V3minie.
should i try in a different PC?
Is there any way to troubleshoot this

kind regards

Hello,

The STM32CubeProgrammer procedure is the same as doing drag and drop. From your screenshots, I got that you flashed properly the Wi-Fi utility firmware. You should have already opened Tera Term with the already-cited parameters. So, you must simply follow the instructions on the terminal. Once you flashed the board through STM32CubeProgrammer, did you get the expected output from the terminal? No phone app is mentioned nor here neither in the README, I'm not understanding what you are referring for. 

STLINK_V3M or STLINK-V3MINIE are similar products. Yours is more recent than mine, but the functionalities are the same. It works in the same way; no need to search for a different PC.

Best regards,

Simone

Hi Simone, Based on what we see here you run the bootloader for MX3080 and load firmware through SPI interface with command script i guess. I found that there is fota upload from cli interface and it could be easier way for users. You can see fota command in cli and soft could be installed from http server. Please explore and consider this option
