CW8.1 for MPC565 - problem in running code in external RAM..

[huzach]

hi!

am using code warrior 8.1 for mpc565 board.

I have two problems.

1. i have been successfully able to download the demo code hello_Fl in the internal flash and it works fine but not being able to download it in the external RAM, it gives an error that 'address(0x10000000) specified for for FPU buffer can not be accessed' and after that the program is run from internal flash.

how to solve this problem?

2. recently i have started to have an exception 'machine check exception 0x0200'.

please help me with this problem.

would appreciate a prompt reply.

thanks

Hi Huzach,

could you may be try with the latest version v8.7 which has been released last year.

In order to switch from internal to external flash, you will have to check the corresponding jumpers, the corresponding registers in the configuration file and the ROM origin in your linker configuration file. All those points are described in the documentation, it is also available in the project when you create it from the stationery wizard for a given target.

Hope this helps...

Best Regards
