Hello, TI teams:
I am using the DRA745 (android 8.1 kernel: Linux 4.4.117)chip for development. I set the machine to mtp mode and connect to the PC. The I copy some files into the machine. But only small file which is smaller than 16KB(16372B) can be copied into it. When the file is larger than 16372B, more 512B increase to the file, it will be OK. Other size increase to the file, it will be failed. I found that it will stuck at the code :wait_event_interruptible(dev->read_wq, dev->rx_done || dev->state != STATE_BUSY) in the function: receive_file_work from the file f_mtp.c until the transmission timeout. Is there any issue about mtp funtion?
