EzPort programmer

[amleng]

Hi all,

I use EzPort programmer explained in AN4406. I could program small s19 files (less than 20K) but I have problem with larger files (100K). Is it fw limitation or something else?

Regards,

I found that I had to decrease the reset pull up resistance to 4k7.

I am using the dediprog programmer in production.

I had so many problems when I first started.

I eventually figured out that 10K pull-ups are not quite strong enough.
