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.
