| Hi All, 
 I downloaded both NAND and SD Card Android image for Orange Pi 2G IOT
 Also downloaded android source and followed the steps are per user manual to compile android source
 I tried to insmod usbserial.ko that is part of the stock image (both NAND and SD Card), it gets loaded properly
 But when I try to insmod the usbserial.ko that is generated when I build android source, it fails with mismatching symbol versions
 Compared the symbol version, they are as below (for simplicity mentioned only two symbols)
 
 
 | Symbol | Stock Nand Image | Stock SD Card  Image | Built Nand | Built SD Card |  | module_layout | 0x54803bd1 | 0xc6d2c755 | 0x27325e60 | 0x27325e60 |  | tty_port_tty_get | 0x64b5d17f | 0x21a53703 | 0x13af3e71 | 0x13af3e71 | 
 
 
 This shows that the config options that were used to build Stock Nand, SD Card android image are different from the sources uploaded.
 Can you please provide the config options that were used for building the stock NAND and SDCard android images for Orange Pi 2G IOT
 
 Thanks,
 Vikranth
