Hi professionals,

Does anybody know an easy way to activate Code Read Protection (CRP) at LPC11xx? We want to protect our IP against piracy. How can I write CRP level 2 into flash location 0x000002FC? When CRP2 is enabled is it then further possible to abuse a flash sector as an "EEPROM"?

Thanks in advance, nerd62 ;-)

There is an example for LPC13XX series that shows how to enable CRP.

With any of CRP levels, IAP calls can be still used to program the flash. Be careful with CRP3, a good idea is to insert a 'backdoor' as detailed in the following AN: http://ics.nxp.com/support/documents/microcontrollers/zip/an10851.zip
