Hello,

I'm trying to get my external SPI flash to work on the BCM943362WCD4 platform.

My first test was to try the new BCM943362WCD4_ext platform, the README says:

This platform is identical to the BCM943362WCD4 platform except that the

WLAN firmware and all other resource files are placed in a WicedFS filesystem

in external SPI flash. This allows more internal flash space for apps.


I just launched it (download run) and I can see that a file system is created ("Creating Filesystem") but it doesn't look like the filesystem.bin is uploaded on the device at all.

So when I run my application without the Wi-Fi firmware in the STM32 flash, I get a "wicedfs init fail".


How can I download the Wi-Fi firmware on an external SPI flash ? Is there any resource explaining how to use an external  SPI flash ? I'm getting confused with the internal DCT of the chip and the DCT stored on an external SPI flash.


Thank you very much.
