Hello All.

I have recently started to upgrade an old board that uses DP256B's with
DP512. I managed to program the board a couple of days ago with no issues.

Today, I ran into a problem with my application code - it couldn't write
to paged flash when downloading data from my PC app. This was quickly
identified as a problem with the bank select in my flash loading routine.

However no matter how hard I try today, I cannot get a P&E Multilink to
load my original binary back into the chip. Most of the time I get "ELF
Loader Error - Unable to program 00C000-00C200". Sometimes this is
different - its all a bit flaky. I have tried two different pods, two
different boards with the same results. An original board with a DP256
works fine.

I have tried using DP512 as the drivative in ICD12 as well as DP256 -
neither makes any differences.

Finally, I find that communications is frequently lost with the board
after the programming failure. Thinking it could be a hardware problem I
have changed crystals and reset chips to no avail.

I think I have had all these problems before and they just seem to go
away. Naturally they come back when under most pressure ;). My previous
questions to the group on similar topic related to Quad Core machines.

Has anyone got any suggestions where I can start looking?

Hi, Jonathan,

Is it DP512 or XDP512=A0?
XDP512 vs DP256 has=20
- a different scheme for quartz than DP256. Maybe it's why you have speed
problem with your BDM, as the CPU run with it security clock, not quartz.
It's the first problem I had when moving from DP256 to XDP512.
- different page addresses (for me, with DP256, my pages begin at 0x30,
XDP512 at 0xE0), so I had to rewrite some code.
- some register addresses are different, so I had to rebuild my projects
with the "good" include file.

I use ICC12 V7 and NoIce debugger.
ICC12V7 options are to generate "Linear S2 file", and NoIce load option is
"S2 have linear addresses".

Hope this help.
Best regards.
Joel

Hi,

DP512 does not have EEPROM or is it XDP512??

I found this type of issues when my memory map was messed up and were writ=
ing errounious data to te flash secure registers locking up the debugger.

So in order to reverse this, you need a generic clock/osc inserted or to be=
able to run the free P&E unsecure program in order to unlock the flash loc=
kout.

To prevent this from happening again carefull analysis needs to be done in=
order to make sure that the memory mapping was implemented correctly when =
moved from the DP256 to the DP512.

Hope this helps

Fred

Jonathan,

Are you using CW debugger? Any chance you enabled Multilink->"At startup CPU
is running (hotplug)" option? This option helps to debug in normal (in not
special) mode of operation, but I believe it should be not compatible with
flash burning. However I could be wrong because I rarely use CW.
