Hi !

I have some questions about the upsd33 :

1. I can run a small code (less then 8K) properly. i put it on csboot0 (0x0000 - 0x1FFF).

But when i want to run a large code (My code is about 60K ) , i can't do it .

Please explain how do i manage this large code ?

Where should i put it ?and how ?

2.does the psd memory(on the psd module) have to start on address 0x0000 ?

3.how do i set a part of memory to Program Space and how to Data space ?

4.do i have to use csboot0-3 or can i set the code to be in main flash with FS0 at 0x0000 - 0xFFFF ?

5. do i have to configure the uVision project as well ? if i work with paging ? and if i dont work with paging ? or maybe merging the code with PSDexpress is enough ?

- Compiler/Linker (UV2): Compile without banking: your code is necessarily less than 64K (UPSD3212).

- PSDSOFT: You must carefully set your PSDSOFT project to make things work:

1 - ''MCU/DSP'' menu - Set the main flash to ''program space only'' and the secondary flash to ''data space only''.

2 - ''Pin/Node functions'' menu - Define the main chip select bits FS0...FS3 to 4000...C000 respectively. Define the RS0 chip select and the CSIOP to locations where the compiler looks for them (XDATA)

3 - ''Merge'' menu - Check that the 4 main sectors have the correct address, and assign to all of them the same HEX file produced by the compiler.

Good luck, Daniel
