Hello all,

I'm trying to use the CAN BAM bootloader on a MPC5644A target.

I'm able to download a simple test program to the RAM using the BAM via CAN, then I try to make this program more powerful and more complex (also bigger dimension), that I can run it correctly in RAM downloading it by the multilink interface but when I download the same code throught the BAM, the program doesn't work, the code download end correctly, it seems to me that the BAM passes the control to my code and then nothing more happens, it seems that the microcontroller is freezed. Are there some code size limitation on the code I download to RAM by the BAM?(Can I use all 192 Kbytes of RAM?)

Are there some other limitations am I missing?

I'm using CodeWarrior 10.7.

Thanks and best regards.
