Please go to the directory ../../usb-1.0/flashdemo and replace

|
|
This example demonstrates how data can be read and written to/from the
|
|
Flash memory.
|
|
|
|
During the start-up the firmware (defined in flashdemo.c) reads the
|
|
number of last sector n from sector 0 (dword at position 0) and
|
|
increments it by one. If n is larger than or equal to the total amount
|
|
of sectors, or if it is equal to 0, n is set to 1.
|
|
|
|
Then n is written back to sector 0 and sector n is filled with the
|
|
string "Hello World!".
|
|
|
|
The host software (defined in FlashDemo.java) reads out the string from
|
|
the last sector of the flash memory.
