I will try with Wouter's hex file on Windows XP as well as Linux to see if it is problematic and report my result here. My test hex file uses all the 8-pins of the 12F629/675 and internal OSC and internal MCLR. Looks like the trick is not universal and the dongle is still necessary. Anyway I hope Wisp648 will be USB based and will have the control over Vdd-traget. ;-) Regards, Xiaofan -----Original Message----- From: Jan-Erik Soderholm Sent: Wednesday, September 28, 2005 6:24 AM Xiaofan Chen wrote : > Even better news is that the "software dongle" seems to work > (erase first before write).

I've *not* been able to reproduce this on WinXP, Wisp628 1.09 and XWisp2 1.7.02 on 12F629 and 675 (tried both). I've tried a lot of combinations of erase, write, target and go... I need to connect Wouter's dongle to be able to "lock up" the 12F's again after flashing b675i-2.hex from Wouters blink-a-led page. That hex uses both intosc and int-mclr.
