PSDsoft Express IAP problem

[avsilverio]

Posted on May 17, 2011 at 12:07

I'm working in a application using the UPSD3234A.

The code is based on the available example in this forum.

I'm having a problem with memory map in PSDsoft Express.

Following the example the memory map is:

Main PSD Flash memory: Data space only

Secondary PSD Flash memory: Program space only

rs0: address 2000-3FFF

csiop: 200-2FF

fs0: (address 0-7FFF) or (page 0 address 8000-FFFF)

fs1: page 1 address 8000-FFFF

fs2: page 2 address 8000-FFFF

fs3: page 3 address 8000-FFFF

fs4: page 4 address 8000-FFFF

fs5: page 5 address 8000-FFFF

fs6: page 6 address 8000-FFFF

fs7: page 7 address 8000-FFFF

csboot0: (address 0-1FFF) or (address 8000-9FFF)

csboot1: address A000-BFFF

csboot2: address C000-DFFF

csboot3: address E000-FFFF

The IAP application requires the same start address for fs0 and csboot0. At this way, the VM register defines where the code runs.

The problem is that I couldn't program the UPSD using this map.

Supressing the start address of fs0 as below

fs0: (page 0 address 8000-FFFF)

it was possible to program the secondary flash, but with this it is not possible to switch the code to run on primary flash.

Is there anything else that could be done to get the first scheme

working? Any help is wellcome.

I attach the report Design Assistant Sumary of my project.
