Hi All,
I'm testing a device which connecting to MCIMX6Q-SDB board thr. SPI interface based on image_imx-android-13.4.1_6qsabresd as the BSP. Have read some SPI discussion in community, all of them are target for Linux, I still try to follow this discussion thread: https://community.freescale.com/message/309184#309184 and apply below changes in my environment:
1. - #if defined(CONFIG_MTD_M25P80)
- .modalias = "m25p80",
+ .modalias = "spidev",
- #endif
2. Enable the SPI user mode driver in by "make manuconfig" and save.
However, when I return to ~/myandroid folder and trying to make whole project, I got:

And then it asks me to select all questions as the same in the menuconfig, trying to select default most questions except System Type:
*
* System Type

..... cut ......
I select 13. Freescale MXC/iMX-based (ARCH_MXC) (NEW) to fit my board, but the next question, Freescale MXC Implementations, it automatically select MX31 platforms without choices:
*
* Freescale MXC Implementations

1. MX1-based (ARCH_MX1) (NEW)
2. MX2-based (ARCH_MX2) (NEW)

choice[1-7]: 4
*
* MX31 platforms:
*
Support MX31ADS platforms (MACH_MX31ADS) [Y/n/?] (NEW)
Finally I select default options for the other questions and keep the building, but failed with errors.I have apply the same based on android_jb4.2.2_1.1.0-ga_source but still got the same result.
My major question is how to config SPI interface in Android, but now it looks like I should figure out above menuconfig issue first. Any opinion or comments are more than welcome!
