I use the USB Interface of the Extension on my custom board by the USB externsion chip of GL850G-28,when I use insert USB disk, I can mount the usb on /mnt of filesystem. But, when I try to read or write on the usb, the fail appear as follow:
mtd: partition "Kernel" extends beyond the end of device "spi_flash" -- size truncated to 0x10000
0x000000010000-0x000000010000 : "File System"

Also,my custom board have the other USB interface which is the same as EVM board,and that USB can read and wirte normally. I'm wonder that if should add GL850G-28 driver into kernel, But I can not get this dirver from the Internet. How can I to solve the problem?
Regard,
Chen
