gadgetfs: usb.c not working on samsung nexus s(exynos SoC)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

I changed usb.c and crossompiled it for samsung nexus s(exynos SoC).
arm-linux-gnueabi-gcc -static usb.c usbstring.c -lpthread

In the kernel I enable gadgetfs module with s3c-udc(s3c_udc_otg.c)

I can mount gadgetfs, but when I run the binary with verbose flag I
get following
output on device side:

/dev/gadget/s3c-udc ep0 configured
serial="adfczl3sdf39idgfo7tdsfv2ss6l3tarbfdfsdjs5m2uffusdflwmfgfs"

If I sniff the communication with Wireshark, there is an error message:
malformed package

Please help! What could be the cause of this issue?
