I am using wi.mx51 development board, i am trying to communicate spi with my slave device.
I am accessing spi driver1.1 from userspace. it's running fine, but
-> Powermanagement IC using spi 1.0 driver
-> i am using spi 1.1 driver
Whenever i am sending data from processor, cs=0, clk, data sending but in output junk data is coming.
when i probe to MISO of slave, it is different to output of MISO of processor.
i found out one difference :
chip select of power management IC (SPI 1.0) is also getting high, when i send data to slave (SPI 1.1).
Both are different chipselect, then how that spi1.0 is affecting ?
