IAR ambiguous section match failed error(Lc037)

Question

I would like to create several Flash region in ICF file, but I encountered some trouble.
Please refer to below link: http://paste.ideaslabs.com/show/bTjeqs7Ymy

I am trying to split flash to different block: Bootcode / Parameter / User code / Discharge areas and I get errors as:

.... many Errors.

The line 71 :place in BOOTCODE_region { readonly, block FIXED_ORDER_ROM };
The line 73 :place in PARAMS_region { readonly };

I am new on this, I would be appreciated if any suggestion! thanks.

My suggestion (which may not be totally correct - (I'm new too, but this is what fixed my issue):

The line 71 :place in BOOTCODE_region { block FIXED_ORDER_ROM };

The line 73 :place in PARAMS_region { readonly };

In my instance it didn't like readonly being in multiple regions. This means you would want your readonly code in PARAMS_region and your other region that has the block be limited to that block. I don't know if there's another workaround.
