We would like to create a custom application and run it on QCA4004 in hostless mode (the application will use the component's WiFi of course).
We understood from the datasheet that the QCA4004 uses external SPI flash and executes the code from its RAM after reading it from the external flash (is that right?)
It leads us to couple of questions:
- What are the limitations for the custom App size? (maximal supported size for App / RAM usage for variables etc)
- How much RAM does the QCA4004 has and what part of it is available for the custom App? (The only info about RAM in the datasheet says 8kB RAM as part of the wake-up manager)
We would appreciate your help,
