I want to drive two spi slave devices on spi1 port, for example A device on cs0 and B device on cs1, the device A on cs0 work well, but the device on cs1 can not work, the cs1 is always inactive. And when I put the B device on cs0, it can work. while the A device on cs1 can not work. why?
My mux config are as follows:
MUX_CFG(DA850, SPI1_CS_0, 5, 4, 15, 1, false)
MUX_CFG(DA850, SPI1_CS_1, 5, 0, 15, 1, false)
MUX_CFG(DA850, SPI1_CLK, 5, 8, 15, 1, false)
MUX_CFG(DA850, SPI1_SOMI, 5, 16, 15, 1, false)
MUX_CFG(DA850, SPI1_SIMO, 5, 20, 15, 1, false)
and spi config is as follows:
struct spi_board_info da850_spi1_board_info[] = {
[0] = {
.modalias = "tlv0832",
.bus_num = 1,
.chip_select = 0,
.mode = SPI_MODE_0,
.max_speed_hz = 25000000,
},
[1] = {
.modalias = "tlv0832",
.bus_num = 1,
.chip_select = 1,
.mode = SPI_MODE_0,
.max_speed_hz = 25000000,
},
};
static struct davinci_spi_platform_data da850_spi1_pdata = {
.version = SPI_VERSION_2,
.num_chipselect = 2,
.wdelay = 0,
.odd_parity = 0,
.parity_enable = 0,
.wait_enable = 0,
.timer_disable = 0,
.clk_internal = 1,
.cs_hold = 1,
.intr_level = 0,
.poll_mode = 1,
.use_dma = 0,
.c2tdelay = 8,
.t2cdelay = 8,
};
