problem erasing flash STATUS_FAIL_PRECOMPACT - aclo...@gmail.com - Apr 2 6:35:08 2008



Hello,
I'm working with the development kit ezdsp320f2808. I'm having problems programming flash. When
I try to program it with sdflash and xd5510usb jtag module, appears this message :
ERR: Erase target algorithm failed.
ERR: Algo return value = 0x0018
ERR: Erase flash failed.
WARNING: THE CONTENTS OF THE SECURITY PASSWORD LOCATIONS
IN THE FLASH MAY NOT BE IN THE EXPECTED STATE. FOR
FURTHER DEBUG PLEASE CHECK THE README FILE INCLUDED IN
THE LATEST PROGRAMMING ALGORITHM RELEASE (JULY 2004 AND LATER)
SPECIFIC TO YOUR DEVICE.

(Status=0x18==STATUS_FAIL_PRECOMPACT)

I have not changed the security password, they still being 0xffff. It couldn't be the problem.
A month ago, I had the same problem, but I could solve it. It was a timming problem. But this
time, I have not idea what could be wrong. I have followed all the Flash API Checklist's steps,
using the samples given, and i get the same message.
Does anybody knows what can I do to solve it?
Thanks in advance, Ana
