I was trying to burn the flash of my dsk so that I could have it run a certain program at boot up. I was using the ti flashburn utility that is an update on the CCS website. I guess I did something wrong specifying the wrong file in the dialog box. Now when i boot up my DSK it is stuck on the second led being lit. Looking at the POST project it seems that it is having problems with the external memory. I tried running the post.out program and it shows the second led hang too, so it seems like the problem is with the sdram, not my attempt and burning the flash possibly corrupting it. Now when I run programs it seems to crash / get lost . Has this ever happened to anyone? I wasn't touching the board so I am wondering what could of caused the ram to get corrupted. The board has been working fine for over a year before this happened. Is there anyway to fix the board? Also is there some reference with a guide on how to convert a ccs .out file to a bootable rom image. Ron |

I did some more tests with my dsk board. I was editing the example post project and I seem to be able to get the board to pass the mem_test if I set the available external memory size as 2 MB, from the default value of 4MB. If I increase the external memory size I end up getting errors at 0x80200020-0x802000a0 (this range varies from run to run). I thought this meant that the sdram was corrupted at those values. However if I change the start location of the test to 0x80200000 I get no errors as long as I only test 2MB of ram at a time. When I increase the testing size I will always get errors. Also it seems like I can edit any location of ram fine using the edit->memory->fill command in CCS. Any ideas on wants wrong with board?

Hello Ron,
On your 'post.out' problem - Check the EMIF initialization
values as compared to the DSK GEL file values [the GEL file should be
correct]. That should solve your "LED 2" problem. If you select the
DSK GEL file in CC_setup, you should be able to load and run programs without
fixing the FLASH.
RE: converting an out file to a "bootable ROM image"
The 6711 ROM boot process is "DMA the first 1024 bytes of ROM into the
first 1024 bytes of RAM and execute add 0".
The hex utility will convert a COFF file to a simple loader format [intel
hex or Mot S-records] that is easily decipherable. see spra544 and
spru186.
