SPI on LPC1768 (mbed)

I tried running a test chunk setting an SPI port on the mbed platform.

This yielded:

eLua# lua /rom/test_W5200.lc 1 1000000
Press CTRL+Z to exit Lua
lua: ?:1646294131: attempt to index global 'spi' (a nil value)
stack traceback:
        ?:1646294131: in main chunk
        [C]: ?

I am running elua version 0.9

The eLua site indicates that SPI on the LPC1768 is implemented, but not fully tested. Has SPI been implemented for the LPC1768 ?

Hi Tom
  This error means that the "spi" module was not enabled in your firmware.
What firmware are you running?

Re: SPI on LPC1768 (mbed)

The chunk was constructed with build_elua.lua using the MBED option for the platform. 

It used the codesourcery toolchain.

That 1646294131 looks quite weird. Are you sure you are cross-compiling correctly? Can you run the source instead of running the precompiled bytecode?
To check if you have "spi" compiled in the image:

elua# lua
> print(spi)

Best,
Bogdan
