I have a program that runs from SRAM (mapped to address 0x100000)
It worked fine on ccstudio 3.1 with serial connection to ezdspf2812.

I installed version 3.3. of code composer studio.
I setup program to continue bh-usb510-c28xx.. I connected the blackhawk JTAG (and disconected
the serial port) from ezdsp.

The problem now is that I cannot run a program from the SRAM.
We have a 64K SRAM on the ezdsp and I cant use them.

1. when linking the program into SRAM I get data verification fail. and I get message:
"Trouble writing memory to block ... at .... on page 0 of length ...
Error 0x00000002 / -2140
Error during: Memory, cannot access memory address at 0x....
sequence id: 66
error code: -2140
error class: 0x00000002"
Of course everything worked fine with version 3.1 , without JTAG
 
2. If I first view memory addr 0x100000 It takes about a minute till I can see the data!
3. After viewing memory link somehow succeeds but then I get stuck in run time and cannot even
reach my main program
 
Please help!!!!

Hi,
   I have not F2812 kit, but I think you have not external RAM correctly 
initialized. Is XZCS6AND7 pin set correctly? Try to start program in 
internal ram, then initialize external RAM, then try to use external RAM.
