Hi all
Using FlahMagic I can program and reprogram the flash without problem when I use it in 12 clock mode. When I set the FX2 in Flash Magic I can only program the first time. Then I cannot do more ISP. I am using the circuit according AN 461 page 12, but with Vpp connect to a capacitor an resitance as state in the errata. Can anyone suggest what else can I do ? |
