Re: SPI bus
Hi,
I am not sure which part block you, maybe read source code will help you understand how spi works.
spi-rt2880.c: spi base driver.
spidev_test.c: used to communicate with driver.
spi-mmc: this driver has queue, it is able to detect the device.

Re: SPI bus
Thanks for responding...
Perhaps when i make a new kernel with Chaos Calmer something goes wrong...
First, what are necesary files for SPI support? kmod-spi-custom, spi-mmc? I dont know... i need a file list....
Second, SPI is native or gpio-bitbanging? and I2C?
Third, how connect spi for a spidev_test... with a loopback? whitout it?
Sorry for my doubts, but in programming aint not good, hardware is better
