Hi, my eval board is Phytec KC-161 (with 64k ext RAM, and 256k ext FLASH). Why the target doesn't initialize arrays in free running? Thank you.
I though Phytec gives you a START167.A66 file with the correct settings of the memory. But it looks like you are using a standard one and as Joost implied you most likely have a problem with this setup.
I believe you have the data set to Flash this is your problem. You need the data in RAM.
I would suggest that you look for this *.a66 file from Phytec or make sure you have the correct settings for SYSCON and only use the RAM on-chip for now. Your memory settings should look something like this:
From the *.lnp file
"START167.obj", "main.obj" TO "test" IXREF CLASSES (ICODE (0x0-0xBFFF), NCODE (0x0-0xBFFF), FCONST (0x0-0xBFFF), HCONST (0x0-0xBFFF), XCONST (0x0-0xBFFF), NCONST (0x4000-0x7FFF), NDATA (0xC000-0xD7FF, 0xF600-0xFDFF), NDATA0 (0xC000-0xD7FF, 0xF600-0xFDFF), SDATA (0xC000-0xD7FF, 0xF600-0xFDFF), SDATA0 (0xC000-0xD7FF, 0xF600-0xFDFF), IDATA (0xF600-0xFDFF), IDATA0 (0xF600-0xFDFF), FDATA (0xC000-0xD7FF, 0xF600-0xFDFF), FDATA0 (0xC000-0xD7FF, 0xF600-0xFDFF), HDATA (0xC000-0xD7FF, 0xF600-0xFDFF), HDATA0 (0xC000-0xD7FF, 0xF600-0xFDFF), XDATA (0xC000-0xD7FF, 0xF600-0xFDFF), XDATA0 (0xC000-0xD7FF, 0xF600-0xFDFF)) CINITTAB (0x0-0xBFFF)
Then you will get something like this which should work.

If you are a student then you can post your email and I will send you a project.

Thank you , Chris Wunderlich.
Yes , I'm a student and I have to do a project to take my degree. My profesor gave me an eval board and have problems at the begining of the project.
Well, if you can give a project with proper settings , my email is damian_dumitras@yahoo.com (or, if it is restricted: damian_dumitras @.. yahoo dot com)
Thank you very much.
I modified the project, except the startup file, and no changes have made... What and how can I modify in the startup file?
I'll send you an example program in a few minutes.
But again check the value of the SYSCON0 register. You need to enable the XPEN bit.
Thanks for the project, and sorry for disturbance. But no changes. I replyed to your mail the results... Is it posible chat anywhere ?
Damian.
Thanks for Chris Wunderlich. The problem was at the project settings. Also the modifications in the startup file solved this problem. Good luck to every body.
