Dear all, I apologize if my question is not a perfect fit for this group.
I am trying to explore the possibility to make use of SPI function in android system. According to the Linux spi document, (http://www.mjmwired.net/kernel/ Documentation/spi/spi-summary) "Many microcontrollers that can run Linux integrate one or more I/O interfaces with SPI modes. Given SPI support, they could use MMC or SD cards without needing a special purpose MMC/SD/SDIO controller." In ADP1, the msm_sdcc driver module handles the microSD card registration and I/O function. I tried removing that module and built a driver/mmc/host/spi module in the kernel image, but when i plug in the microSD, nothing happens in the kernel. Is it possible to use SPI mode to read/write the microSD card? Anyone has similar experience? Thanks a lot in advance! jintao -- unsubscribe: [email protected] website: http://groups.google.com/group/android-kernel
