Hi guys,

 

I am trying to migrate a hardware from MPC5643L to MPC5744P following the document attached in the following link:

 

http://cache.freescale.com/files/microcontrollers/doc/app_note/AN4624.pdf

 

According to the document, the chips are pin2pin compatible except 3 pins that if you have connected to Vdd it couldnt be a problem.

 

I have created a small design with a blinking led, and i am able to erase and program the microprocessor but when i try to run the program it gets stucks and the led never blinks.

I am generating the .elf with the MPC5744P  MCTOOL BOX and the same program generated with th MPC5643L MCTOOL BOX for the MPC5643L is working without any problem.

 

Has anyone experienced this type of problem? Any idea PLEASEEEEE.

 

Thanks a lot in advance.

 

Pablo
