Hi Simon,
I did find the RTOS SDK, but I'm an old bare-metal die-hard. I need to
keep the AT commands too, and that seems to be supported on the non-OS
SDK (but I didn't dive too deep).
I also found some guys that have run some diffs and created some
patches, and then provide a newer stack. That is a "cheaper" alternative.
This beast has little RAM and no ROM, it pulls code out of an SPI flash
to RAM or to an execution cache. Those fancy attributes are to put
functions on the execution cache, freeing valuable RAM for heavy use
stuff. What worries me are those os_ prefixed functions, the chip has
been crafted to work as a wifi machine and basically other use is
robbing processor to its main function, so fooling around with something
not provided by the manufacturer can easily turn to a nightmare. Not
that what they provide can't... but seems to be somewhat more "tested".
I think I'll stay with the stock stack until there is a real need for
production-quality code (and someone to be charged for its generation).
Thanks for your comments!!!
