Unable to burn neCORE12M64 flash memory...

Postby alejoverdin » Mon Mar 12, 2007 4:52 pm

Hi everybody,

I am currently trying to work with NoICE along with a
microBDM12LX pod but burning demo uIP programs into neCORE don't
seem to work. Using the LOAD command from NoICE I select
demo-ne63.s19 file, but soon after prompts the following message:

BDM Communications Problems ...

and ask me to choose or edit a diferent frequency.

Something interesting to remark is that NoICE cannot reset the target
properly without a actually pushing down the POD's RESET button.

Besides I need the schematics of neCOREM64, where can I dowload it?

Bests regards,

Alejandro Verdin

neCore12 problems

Postby cbarnes » Mon Mar 12, 2007 5:27 pm

Hi Alejandro,

Sometimes BDM communication problems happen because the voltage regulator on neCore12 gets too hot and shuts down temporarily when a BDM pod is attached. When you use a BDM pod, it's very important to limit the Vin going to neCore12. Feed in regulated 5V on the Vin pin or better still, use an external regulated 3.3V supply connected to the Vcc pin, and leave Vin open. That way your external supply can provide the extra needed current for the BDM pod.

By the way, I sent you the schematic via email-- it is not available for download.

I started working directly with DBUG12 (ver 4.0.0b32) using TeraTermPRO and
discovered I could erase the entire flash eeprom this way

fbulk ;np

no allowing PLL be enabled. So, to load .s19 was similar:

fload ;np ;b

and then "Send the File ..." under File menu. But the neCORE isnot working
yet, but the thing I am worried the most is to be no able to use the NoICE
debugger ... I guess it is not aware about how to switch off the PLL on the
neCORE. I need help.

Thanks in advance,
Alejandro Verdin
