Hello Guys, I need some support around firmware transfer to uC with Android OS. I have problem with firmware transfer (*.bin) from Android tablet 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 wont execute user firmware. The firmware loads into the uC successfully.
The whole firmware transfer process works on windows PC without any problems.
Are there any compatibility problems, or settings to overcome this problem on Android tablet?
I think I'm not only one who was tried to transfer *.bin file to uC from Android tablet.

The FAT file system support on Android derives from Linux code.
And then, the workaround for Linux will be applied.
