Hello, could you tell me, wether the AN2131 from Cypress shares CODE and XDATA-memory? And how do I have to configure the CODE and XDATA-spaces in the BL51-dialog?
Regards, Stefan
I think my problem is solved more or less quickly for someone who is experienced with memory-mapping or how it's called (the thing you do in the "BL51 locate"-dialog): I wrote a program, which is based on another, smaller program. I kept the settings of the originally (small) program (see screenshot here: www.loaditup.de/413999.html). But I think through the originally settings in this dialog the used memory is very limited... So I want to ask, what I have to modify on this data to be able to use a maximum of the memory of the AN2131S (without any additional RAM-chips or things like this).
The link to the datasheet of the AN2131S: www.datasheetarchive.com/.../DSA-596164.pdf
Doesn't anybody has an idea???
I think if you want someone to do detailed research for you, or to give you detailed training, you probably need to look here: http://www.keil.com/condb
hello my freind,
the an2131s. it is long time when i used this but i remembar some of it still
it shares some space for code and xdata. it is a processor for usb and has something called *** renumeration ***. this can be v good for some projeks becoz the (pc) driver can send code to the device when it connects. code downed to xdata space and run as code.
why do'nt yo look at the datassheet in section 3.1 and u see the detail.
always yo're freind.
In the datasheet in section 3.1 there is a memory-map, okay. But which one is the right? There is a 4kByte and a 8kByte-memory-map... When I know, which one is right, then I also know, how much RAM I have to divide into XDATA- and CODE-memory for the program?
helo again my dear friend.
the datasheet does give the information. but yew must learn to read it and understand it. even poeple who say they are profesionals sometimesdo not do this (yew know who yew are!)
but now for help for yew. look at section 1.17 of the datasheet. it has feetures for each processor in teh family.
good luck in yo're work. i must go agin. forever. arivirerchey.
Zeusti.
Oh, thank you very much Zeusti ;-) Sometimes reading can help... Okay, and refering to the 8kByte-memory-map I have the addres space from 0x0000 to 0x1B3F of the RAM for free usage and I have to divide this into a CODE- and a XDATA-space?
I hope, you won't kick the bucket :P
