Programmer / Image Clone Help Needed

Postby northwaytv » Tue Aug 28, 2012 1:43 pm

Hello,

I hope i have posted in the right area, I work for a TV repair firm and we are starting to see allot of Flash Ic Failures like the one below.

http://www.digikey.com/product-detail/e ... ND/2744748

I am in need of a way to copy an image from a working IC and then program it to a blank. The manufacturer Am Tran is of no assistance in providing the files or the part pre-programmed. Does anyone have a recommendation on a device that would preferably clone the image file while still on the board, and be able to program it to a blank Ic. If cloning on the board is too difficult, one that does it standalone would be fine.

Thanks in advance!

If the PCB design is such that manufacturer was programing in place, then
answer of course would be yes, via a bed of nails to pickup signals to device,
primarily address/data/power.

But if memory connections "hard" on the board, meaning you cannot drive them
because they are terminated in various ways, and by driving them with other
parts of board not poowered up possibly cause damage to other components.

Part could be removed from board, put in a jig, and read back to get
programming file, if a memory part. You could use a basic controller running basic
language, several on market, to do the job.

Compounding this is if device is a UP, it probably has FLASH security protection,
simply put you would not be able to read it once that bit is programed in the
part.

I do not believe the board was designed to program in place, which is not that big of a deal. I will only be copying the file once, and then programming it to blank ic's.

Understood

language, several on market, to do the job.

This will probably be the best method. Do you have any recommendations to a "good" controller & software combo?

I have wondered if security would be an issue; however a few other shops have done this successfully. So hopefully it will work.

Thanks for your help! David

If your are programming in basic then basic stamp has the biggest following I think.
Basic Micro would be another.

There is stick OS that seems to have a recent uptick in followers.

Even better would be PSOC 3, its ease and speed of project creation tops pretty much
most other vendors. For ASM and C programmers. Then there is Arduino.
