WICED Studio Wi-Fi Combo

Anonymous
Not applicable

The ota_fr test app builds but seg faults when it tries to download. I am testing with a BCM943362WCD4_3 board. When I try and integrate the ota server code into my application it seems to work with respect to running the AP mode and managing the HTTP transactions but it only intermittently reboots correctly and even when it does the code has not been written properly. I added some debug printf's and it seems that the sflash inteface is not reading/writing properly because it reads an app_header.count = 0 and this causes wiced_apps_get_physical_address() to fail, which ultimatley causes the process_upgrade_chunk() to fail, even though it's not inidicated in the WICED console output. Any help would be appreciated!

(1) Log except from my application runing the wiced OTA server(note that this log as the augmented debug output I added) :

First you should replace your tools/Linux??/common/make with your system make to fixed the Segmentation fault under Linux!

Then build the ota_fr with download_apps to download the ota_fr into external flash include APPS_LUT !

Sorry,

The module is: BCM943362WCD4_3

The eval board is: BCM943362WCD4_EVB (Rev 1)

Hello,

Could you make sure your makefile is as follows:

snip.ota_fr-BCM943362WCD4 download download_apps run

It is important to include "download_apps" in your makefile name.

Thanks,

Arsh Buch

This is correct, but a little more detail would have been helpful.

The ota_fr demo app build fails when the 'download_apps' option is passed with Broadcom's version of make, located in this directory:

.../WICED-SDK-3.3.0/tools/common/Linux32

FIX: replace Broadcom make with the native make:

mv make make.orig && ln -s /usr/bin/make make

With the above change, the ota_fr test app can be built and downloaded correctly, even with the

download_apps option.. After ota_fr is run,, the DCT image in the external serial flash is updated with application header/location/size information which the OTA process uses. Attempts to perform OTA upgrade will now succeed from either the ota_fr test app or from a user application calling the ota server.
