in Propeller 2
These flash chips are bigger than 512 kB so they can be used for resources and data
Does the command "program flash" in Propeller Tool and Flexprop erase all the flash chip?
If not, is the erased range configurable?

I have been using 32MB Flash on my latest RetroBlade2s with the flash option. Certainly a lot of space here to something amazing. The bulk erase seems to be slightly different.
IIRC correctly it’s an S25FL256.
If I remember correctly the decision was made to use the first 1024 Kbytes reserved for the boot image, just in case we get a 1024 Kbytes HUB in another P2 variant.
So user data on Flash should start at HEX 10000 (after the first Megabyte) and is save there from the boot flash loader.
Enjoy!
