Hello Aykut Birsen,
I am also having same problem of booting from external serial flash.
I am using SST25VF040B serial flash.
I have connected SPI1_DATIN Pin to the ground with 100K resistence. but still its not taking code from serial flash.
But with osilloscope i can see the out put waveforms comming out from ext serial flash's pin 2 which is SPI_DATA_OUT. after the reset.
could you please help me with circuit(with SPI1_DATIN Pin)connections and that code which u loaded into ext serial flash. for my reference.
Thanks in adavance.
What makes you think "Aykut Birsen" is waiting for a message from you? Ho, you're right: He's sitting next to his phone waiting for a call! Better do something about it then!
This looks like this is a continuation of the (now read-only) thread:

The world is filled with lazy, unqualified, unconscionable software/hardware people who think they know what they are doing. The slightest setback will discourage them and make them attempt to steal, pillage, and plunder! Sick of them.
Tamir,
Just for once I wish you'd stop being polite about peoples posts and just say what you really think ;)
Oh dear, Tamir - are we having a bad day...?
Sorry guys.
YES!
"Just for once I wish you'd stop being polite about peoples posts and just say what you really think ;)"

shame on you..!! You just stop worrying about world.. If you know somthing then just do reply otherwise i have not forced to you to do reply.
Its very discouraging for the new commer who tries to come in embedded domain.
I have stucked thats why i am asking..!! and Somebody already gone through such problem then their is no point in doing RND..
thanks for your promt reply.. i will remember this thing while posting next time.
Does this mean that Aykut Birsen gave you a call after all?
hey Tamir why u are spending your valuable energy n time giving irrelavet answers..
"Does this mean that Aykut Birsen gave you a call after all"
that i will see what to do..?? Thats not your business..
n don't reply. if you know or don't know the solution..
Actually, since you have posted it in a Public forum, you have opened it to public comment.
If you want private consultancy, where someone will focus specifically and solely on the issues that you specify, then you must expect to pay for that. On a free, open, public forum, you must take what you get.
"Beggars can't be choosers"
And, striclty speaking, this forum is supposed to be for discussions about Keil products - not general microcontroller design issues!

"Thats not your business.."
I do agree with andy (or his generation) here. if you don't want to be ridiculed, you shouldn't have posted your private messages in a public forum.
... then don't make posts that invite ridicule!

hello, Actually its my mistake that i have initiated the problem with someones name.. sorry for that..
but reason behind that was this problem already discussed.. thats right.. but that was now read only that to it ended with successful result that's why i thought may he will or someone will help..
I did't asked for ready solution..but he replied in such a language that "He knows all things from his child birth"
@Neil thank's for your link..
I am already following same path.
everything i read from Lpc manual about booting sequence i am trying for this Ext_SPI_Boot problem for many days but where i am going wrong i did't understand.
and then i started finding solution from net thinking that if somebody already gone through this problem then he could help me.
now i am going to post some code snippets that will give some overview about what i am doing..
case PROG_3250: /*8*/ { Delay(5000); if(Prog3250Flash()) { Delay(5000); if(Verify3250Flash()) { //Success break; } } }
here it is running succesfully.
but while loading code using KEIL+ULINK I am not finding right setting for my serial flash I have mentioned.(SST25VF040B)
i have tried with all possible settings avilable in "TagretOptions->Utilities->Settings->adding device"
Which one to take that one confusing.!!
Screen shot i can't attach..
