Problems with OTA2: flashing device and firmware_reset (con't)

[JoSt_3481606]

Per this closed thread Problems with OTA2: flashing device and firmware_reset​

I have followed the same tutorial and got to the same point with the exception of being able to load new firmware via the web upload.

I am able to load the boot loader and default firmware and can restore from the factory download area holding sw1 for 10sec on boot.

I can get it into firmware upload mode sw1 for 5 seconds and load the webpage.  I then start a transfer and the progress bar goes past 100 and the device never reboots and updates.

I have tried manually rebooting with no success.  It just goes back to whatever firmware was currently active.

I am generating the firmware using ota2_image for the one I am using to update from the webpage.

Hello:

snip.ota2_extract-CYW954907AEVAL1F

snip.ota2_example-CYW954907AEVAL1F ota2_factory_download

snip.ota2_example-CYW954907AEVAL1F ota2_image download_apps download run

snip.apsta-CYW954907AEVAL1F ota2_image

// This is the image which will be updated.

//  after reset key pressed,  press button 1 for 5 seconds

do the update process by using web server provided in ota_extract .

and I did the same process twice, It was finished successfully .

I stilll cant get get this to work.  I am on 6.2.1.  I wasn't able to get the snip.apsta to build unless I add these lines to the make file

#OTA SoftAp application

OTA_APPLICATION := snip.ota2_extract-$(PLATFORM)

OTA_APP    := build/$(OTA_APPLICATION)/binary/$(OTA_APPLICATION).stripped.elf

This is the error on the initial build

Then when I uploaed the stripped elf using the webpage, the progress bar goes beyond 100%.  It never reboots and a manual reboot doesn't cause the firmware to load.

Hi：

#OTA SoftAp application

OTA_APPLICATION := snip.ota2_extract-$(PLATFORM)

OTA_APP    := build/$(OTA_APPLICATION)/binary/$(OTA_APPLICATION).stripped.elf

This  is  a necessary step:

and like what I have posted,  extract application should be compiled firstly also.

snip.ota2_extract-CYW954907AEVAL1F

Can you clean all the compile and do it according the steps I posted  ?  thanks.

[JoSt_3481606]

as I stated previously, I have done a clean compile and was following your steps.  Can you tell me what browser you are using to do the upload?  I was using safari to upload the snip.apsta-CYW943907AEVAL1F.stripped.elf. 

Is that the correct file?  Is it a problem with safari?

I built all the files on windows, but used my mac to upload as that is the only machine I have with wifi to connect to the soft AP.

[Zhengbao_Zhang]

Hello:

   Yes,  I think the difference is I am using windows firefox to visit wiced_ota_server/upgrade.html .

and I verified my steps , it worked well.

[JoSt_3481606]

I tried windows Firefox and got the same result.  Progress bar keeps going past 100% and device never loads new firmware.

I tried windows chrome, Firefox, Mac safari, Mac chrome, Mac Firefox all with the same results.

Any other thoughts?

[Zhengbao_Zhang]

hello：

   it is better you can show me your steps , I have no idea about the failed status since I am working well all the time in my side.  and what is the application will be updated into staging area ?  Can you send the bin file to me for a try ?

6)boot into soft ap mode holding sw1

7)browse to webpage and upload snip.apsta-CYW943907AEVAL1F.stripped.elf

Here is the output of the terminal.  It just stops after getting all the bytes

I have included the entire build directory.  If I reset the board it also doesn't load.

[Zhengbao_Zhang]

Hello：

last step, you need to upload the .bin file .

   The OTA2 Image Packager Application will combine all of the assets into a linear file which has a length and CRC for easy retrieval via the HTTP protocol. This will include Executable Application, DCT, and File system (resources, WiFi Firmware, etc.).

[JoSt_3481606]

I just tried the .bin file and got the same results as before.  Progress bar goes past 100 and it never reloads and updates the firmware.

[Zhengbao_Zhang · Accepted solution]

Hello:

this directory, this  file:

build/snip.apsta-CYW954907AEVAL1F/OTA2_image_file.bin

not the binary directory .

[JoSt_3481606]

Wow, that was a lot of effort for something so simple.  Yes that is the correct file and it works.  I think the confusion is in the documentation.  There is no reference to the soft ap upload tool or the correct file in WICED-OTA2.pdf  IN WICED-OTA.pdf on page 8 and 9 it tells you to use the stripped.elf file that is in the bin directory.

The WICED-OTA2.pdf never explicitly specifies the path for the update ota2 image.  Maybe that should be make more clear.

Thanks for your help.

Should I interpret your marked correct response as the following:

After the kit is programmed then reset into OTA boot mode and you've accessed your device from your PC and navigated to 192.168.10.1, load the .bin file named "OTA2_image_file.bin found in the build/snip.apsta-CYW954907AEVAL1F directory. Do NOT use any .bin file from the lower build/snip.apsta-CYW954907AEVAL1F/binary directory.

[JoSt_3481606]

That was the issue. There should be explicit directions about where to get the bin file in the pdf that described the process.
