Problem with power to JDM programmer

Started by miketurner772003 April 6, 2004
I'm trying to program a pic12c509 with IC Prog through a baby
programmer, but get the following message when I try to program all.

"No oscilator calibration value found do you want to use the value
from file OFFFH instead?"

Whether I click yes or no it goes through the motions of programming,
but gives me a message at the end " verify failed @address ooohi" I
believe the issue is a power one with the software not reading the
pic due to not enough power getting to the JDM. How can I sort this
out??

I have heard you can set up these programmers to be powered by
battery, but I cannot find any plans and my soldering skills are not
great anyway. Any other ideas???

this is not a jdm problem, the oscal value must be present at the and of
your program memory space (last location). The softfare is trying
to read that value, if you deleted by mistake it found 3FF instead, so
you can't do nothing.

The same error occures if your programmer does not read the PIC (you
don't have the right Vpp)
or the connection between the PIC and the programmer is wrong >

There are at least 10 versions of jdm, we can't talk without seing what
hardware you have.
