Problem with the memory map file - zeki...@yahoo.com - May 25 8:25:45 2006



Dear Radu,

As far as I can see you are using the external memory to download the code.  I am having the
same problem whenever I would like to use Full Memory Map option from DSPTgtPkg Target
Preferences Menu :((.  Matlab and TI support could not resolve the issue yet.
 
The interesting thing is I am trying to run the demos provided by Matlab. (e.g. PWM Duty Cycle
Control via Period Change c2812pwmtest.mdl or any other with Full Memory Map option)
 
Matlab support offered me 2 options
 
1) the RAM is dead ???????
2) in CCS  go to GEL menu --> Code Security Module --> Unlock_CSM
 
The first option is not possible for my application because even though some information is
missing CCS still downloads the rest of the code which are not dependent on the missing
sections. Moreover, I can see whats on this part of the memory using View --> Memory  go to
0x100000 or the problematic area 0x108000.  
 
Second option did not change anything either. According to SPRU078 pp.2-5 XINFT Zne 0/1/6/7 are
not affected by CSM. Try these if they work for you. It did not for me. Please let me know
about the situation. I am in desperate help as well.

Regards,
 
Zeki Akcali
 
Note!..  I have checked the f2812.gel file and the memory map c2812pwmtest.map file generated
by Matlab and the command file c2812pwmtest.cmd file by CCS.  There are no conflicts or
whatsoever.
