Help for USB Secondary ISP Bootloader for lpc214x


I download the USB Secondary ISP Bootloader example for LPC2148 to use for Keil MCB2140 board at

The bootloader works as an USB Mass Storage to upload the user application into flash by copy and replace the firmware.bin.
It works fine on window PC when I copy my binary file to replace firmware.bin. After I reset the board, it will jump to the user application location and run the user application.

But it does not work on Linux, I use opensuse 10.3, when I copy binary file to replace firmware.bin. Sometime, it did not allow to delete the firmware.bin and it never run after I reset.

Can anyone show me how to fix it?
