Mother of all 7603 XDF files
Re: Mother of all 7603 XDF files
I added some sections to the XDF to look at the data in the parameter blocks.

Don't stress specific units.

Re: Mother of all 7603 XDF files
I dont know exactly whats in them, but I can speak to that area generally. Thats the Paramater block segments on the flash. They are mirrored to SRAM at FF8000, and are used to save that persistent data to flash. When it is being persisted some operating systems move the active block to the alternate param block, and others always use the same one. So Dynamic Data 1 is the Param block at 0x4000 and Dynamic Data 2 is the Param block at 0x6000. It looks like they are named 1 and 2 for the two copies. Only one will be active at any given time, and the other should have FF in the whole segment (erased). So the question would be to figure out what saves error flags to SRAM at FF8040 (as the offset is 40 in the XDF) and there will be a flash backups of that data at 0x4080 or 0x6080 as Dynamic Data block 1 or 2 error flags, and the other will be blank - FF.
