can I get source for the KL25Z bootloader?

I would like to modify the mbed virtural fat system to add 2 files as follows:

1 file would be named in_data.dat that would consist of a 256 byte record that would write to a fixed location in RAM. 1 file would be named out_data.dat that would consist of a 256 byte record that would read from a different fixed location in RAM.

both these files would only support read and write and all records would go to the record 0 locations. (not support create, delete,etc.). Would need extra interrupts to signal that external read or write was complete.

This should support fast communications using only file IO from windows, Linux or any OS and greatly simplify host software.

Hello Jim Spruell,

do you mean openSDA bootloader? or msd drag 'n' drop loader available in CMSIS-DAP?

openSDA bootloader I think. I am not sure what the msd drag 'n'drop loader is and if it will work with the KL25Z development card.

I meant msd - mass storage device. The openSDA bootloader (enter the bootloader mode by pressing reset button) is not shared in CMSIS-DAP sources. I assume its sources are not available, thus we need to write our.
