The problem is that it was made for the LPC1768. When it was made BurstSPI only supported the LPC1768, this is no problem, meanwhile it also supports the KL25Z, and updating burstSPI removes that problem. Problem two is that it writes its own flash memory using the IAP library, which doesn't support the KL25Z.
Final issue is that then it will compile, but the KL25Z only supports 8-bit writes, not the 16-bit of the LPC1768 (and some others). I don't know if Frank has time/interest in fixing this right now properly, but for me it will for sure not be very soon. That said if you just want a dirty fix for yourself, you got to:
Update BurstSPI lib (click on it, click update at right side).
Delete IAP folder, and all related errors to it (they should all be between #ifndef NO_FLASH_BUFFER).
Finally, everywhere there is spi.format(16,3), remove that one, and replace the subsequent fastwrite line by two lines:
_spi.fastWrite(color>>8);
_spi.fastWrite(color&0xFF);
(Of course assuming the original was color).
Hi Bryan,
The error you get is related to the BurstSpi code and probably indicates a wrong platform selection.
Can you publish your code or give more info on your project: platform, spi pin declarations, ....
Also make sure you use the latest mbed libraries.
As a test, I re-compiled the demo code with all libraries updated : I got no errors.

edit : the mbed site seems a little slow today - Erik's reply only appeared after I sent my reply. I'll try to free up some time to fix the problem.
Thanks guys,
After following your suggestions, it's compilable now and trying to understand the program.
Best regards,
Bryan
Btw Frank,
How could I share my code to you?
Thanks,
Bryan
Hi Bryan,
Sorry I did not reply earlier but there seems to be a problem with the mbed site forwarding messages as I did not get an E-mail with your reply. As for sharing your code, you can upload a zip file using the insert images or files link above the comment window or publish your code as non-public and send me a pm with the link.
I just started reworking the ILI9320 code to allow the use with other mcu's (apologies for the delay).
