Atmel 89 Series programmer problem

[shamikrudra]

In my home made PCB, programmer is working it is identifying the 20 pin chip in the socket but 40 pin socket is not identifying device. as I made two PCB for solving problems. but both has same problems. I checked all the soldering and found connections are working properly. so I ordered the PCB from professional manufacturer and programmer is working from first run.with out any problem.

Re: sunrom 1001-3456 Firmware source

You are talking about Hex code and I am talking about source code of the programmer.

@vaslvsb
I ordered PCB from a local manufacturer in Kolkata.

He uses the S52 as the controller. Remaining are all discrete and passive devices.

I believe there is a problem in the Vpp control circuit but I cannot be sure until I see the source code - so I am waiting for p55xp to upload the code.

Assalamualaikum hey buddy I had the same problem. It got resolved when I changed my UVision software. I also pondered into the hardware. Now here is a HEX file that you should try will burn at the instant, If so then change your Programming software VERSION to older i think
