Convert BMW Fxx programming files to programmers to read and write files

Dear gods, can anyone explain the programming files of BMW's original Fxx chassis, such as swfl_0000074c.bin of CAS4, according to the original programming sswfl_0000074c.xml, but I did not find the flash address indicated:

Data segment read by CAS4 programmer
The first paragraph, 0000000--000B0BF
The second paragraph, 00000C0--00040BF
The third paragraph, 00040C0--00070BF
Fourth paragraph, 00070C0--000B0BF
Fifth paragraph, 000B0C0--000F0BF


Original programming file data section - sorry I didn't find it?
0FE8000--0FE8FFF?
C004000--C007FFF?
C00C000--C00EFFF?
C3C8000--C3CBFFF?
C3D8000--C3DBFFF?

Thank you all gods!

Time to reverse the CBOOT then, which you will have to do regardless, as all the flash data is usually compressed and encrypted.
