Hello,
I use the AN2131S and want to be able to use the whole available memory the AN2131S has (without any additional RAM-memory). I use µVision3 from Keil and ask for the settings I have to make in the "BL51 locate"-tab of the "Options for target"-dialog.
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: http://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.
A second question: Are the xdata- and the code-spaces both on the same memory (the XRAM)? And how much XRAM has the AN2131 (I read something about 4k or 8k)?
Regards,
Stefan

AN2131S has 8k RAM... This part is obsolete for a very long time... May i know why you are experimenting with this part???
This memory is shared by code and data....

I am a student, who has built a usb-board with the AN2131 in school... I know, that it is a no longer current device, but i have this board 😉
