No Algorithm found for: 20000000H - 20000B2FH

i am doing project on AT91SAM9260 controller, but when i am trying to download executable file using JLINK it fails with:

No Algorithm found for: 20000000H - 20000B2FH

Here's the log output:

Google returns a few results for "keil no algorithm found for" e.g.

http://www.keil.com/support/docs/2831.htm

If that doesn't help investigate some of the others.

Hi,

this nomally means that you forgot to select an algorithm in the third tab of the target driver configuration dialog (utilities -> select JLink driver -> 'Add' and select "your" flash algorithm from the list.

That should work. If not, please report this problem to keil support, and I'll solve it when I'm back next week.

BR,
/th.

hi,

i had tried to add algorithm in utilities -> select JLink driver -> 'Add' and select "your" flash algorithm from the list.but i didn't find any algorithm for AT91SAM9260 (SDRAM). can you help me out to solve this problem

 RE: this nomally means that you forgot to select an algorithm

I think it can also mean that your memory set-up is wrong?

As the message suggests, the Algorithm needs to be correct for the specified address range - so, if the address range is wrong, you can get this message.

 RE: this nomally means that you forgot to select an algorithm

I have a feeling that the Algorithm could be one of those things that uVision-3 stores in the "wrong" file; ie, it stores it in the project.opt file, rather than the project.uv2 file?

This means that, if you save/copy just the project.uv2 file, you lose the Algorithm setting and, therefore, you are likely to get this error the first time you try to debug...
