Applications Information
3. No action necessary on “Command Complete” events.
Some way of reprogramming the files on the host must be considered.

10.8.4.2 One-File File System Downloaded to RAM in MC72000
This will download an image of all files to RAM in MC72000. This saves the EEPROM and no parser/
router must be present when running application and upper stack code.
The download of this image is done once under the initialization of the MC72000.
This functionality will be available from ROM 2.1.
No EEPROM is needed, but the host must have initialization software that can make host connect and send
one file after all resets. Furthermore, the host must store link keys, if needed, and send those after each
reset.

Motorola Bluetooth File System, Host Based One File Application Note
(document
number 94001481004).
10.8.4.3 File System in EEPROM on MC72000
An EEPROM containing the files is connected to the MC72000. The parser/router part does not exist in
this configuration and the upper stack are directly connected to the UART driver.
Some way of reprogramming the EEPROM normally must be considered. This can be done through JTAG
with special programming, or directly through UART interface with a parser program.
This solution will add the cost of an EEPROM but will keep the host software simple.
