Hi,
I have built and used Sunrom programmer 1001-3456-v2 (ProLoad Ver. 5.4) for the last 6 months for AT89C52/AT89S52, and am satisfied with it.
Now I want to program AT89C55WD. This always gives an error on Verify Fail at Address 1.
When I put this IC into another USB programmer(UNIPro), it shows blank.:!:
The same AT89C55WD gets programmed in USB programmer(UNIPro).:!:
Whereas the Sunrom programmer is working fine with AT89C52.:!:
Once this Sunrom Programmer worked on 2 of AT89C55WD, but after some time, it started giving the same problem, with the very same ICs. But the ICs are OK when checked in UNIPro programmer.:?::!::!::!:
Is a new version of hardware/firmware/software needed?
