hi Bin liu,
in my device tree (am335x-bone-common.dtsi) usb setting and in my customized file system gadget_init service file are missed.
i added those files, now it's emulating /dev/ttyACM0 and boot partition as a mas storage in linux.
i have below problems.
1. i am not able to copy files into boot(mas storage) partition,it is giving error(read only file system)
2. i want to mount boot partition in rootfs to copy data from other mechine using mas storage (boot)partition . is it possible?
3. how to enable acm, mas storage with nand falsh.
4. acm, mas storage devices are not emulating in windows 10, please let me know what could be the issue.
thankyou.
issue fixed.
