Still having strange problems with SRAM and FLASH

Let me correct the table to make it more clear:

TEST# clkdiv .reset... .except .... .text .............rodata+.rwdata T.PASSED?

1...........8........EPCS.. int_ram ... int_ram ........int_ram ........................Y

2...........8........EPCS.. SRAM0 .... SRAM0.......... SRAM0 .........................Y

3...........8........CFI..... int_ram ....int_ram ........int_ram........................ Y

4...........8........CFI..... SRAM0..... SRAM0........... SRAM0........................ N

5...........8........CFI..... CFI.......... CFI................ Int_ram........................ N

Interesting is combination of tests 2 and 4 or 3 and 4.

If# 2 AND# 3 works, why# 4 or# 5 does not work??
