Hi Joep, Sunnish,

I had thought of LVP. The LVP pin was not connected, but I had specified
LVP disabled in the fuses and programming via wisp648 seemed to work OK.
But I have installed a pull-down now to exclude the possibility of LVP
disturbance.
The connection between PicKit3 and the test board (a Pickit-Wisp648
converter cable) had a (partial) short circuit. I discovered this
because also other boards with other PICs could not be programmed, while
a board with 'native' Pickit connector
So the issue with PicKit3 is solved.
To my surprise after programming the 18f6723 with Pickit3 the led
blinked, while when programming with the Wisp648 and Xwisp2 no blinking
anymore! Although programming (incl verify) with wisp648 seems to work
fine, I suppose this is a problem with Xwisp2, which I'll have to figure
out...
Thanks for thinking with me!

Hi guys,
I wanted to test a blink-a-led sample for a new 18f6723.
Programming with the wisp648 and xwisp2 worked fine, but the led
didn't blink. Then I took a 18f6722, which I'm sure worked in the
past: same story! But with 18F6680 the led blinks! All with the
same test board, only a different PIC (each on its own plugin
daughterboard).
Then I tried to program the 18f6723 with a Pickit3, but now the PIC
is not even recognized, while it was correctly recognized by the
wisp648. It got a device ID 0x0 in stead of the expected 0x1400.
Same with the 18f6722 and 16f6680 (bot deviceID 0x0).
Any suggestion where to search for the cause?
Regards, Rob.
