Firmware transfer *bin from Android to uC

Franc Hanzic

Hello

I use USB bootloader for NXP uC for firmware upload. But now I have problem with firmware upload (*.bin) from Android PC to uC NXP LPC1768. The point is that the android PC find the uC memory and I can transfer the firmware. But after reset the uC doesn’t accept firmware.
The whole firmware upload process works on windows PC without any problems.
Are there any compatibility problems, or settings to overcome this problem on Android PC?

I’m using:
uVision 4.53 for programming and *.bin generation
Android tablet PC: Galaxy Tab 10.1 for firmware upload

Best regards

    I made some file compare (CompareIt! 4.2).

    First compared file: transferred to uC from windows PC and works. The file was copied back to PC from uC for analysis.

    Second compared file: transferred to uC from Android tablet, non working. The file was copied back to PC from uC for analysis.

    Analysis results:
    Second file was drastically changed. The hex viewer shows some changes from address 0x00000400 to 0x00000C00. There was also some additional code inserted from 0x00000C00 to 0x00001000. So, this file contains additional nonsense code.

    This happens only by file transfer to uC via USB. I have randomly copied the file on the Android tablet and then back to windows PC. The file was not changed.
