Hi,

I am getting following error whenever I try to send data on /dev/spidev1.0 (which I assumed is spi1 master connected to IoT Expansion card slot :

[184.364669] spi\_qsd 78b7000.spi: msm\_spi\_clock\_set: no match found for requested clock frequency:96000

[184.392745] spi\_qsd 78b7000.spi: msm\_spi\_process\_transfer: Error setting QUP to reset-state

[184.505272] spi\_qsd 78b7000.spi: msm\_spi\_process\_transfer: Error setting QUP to reset-state

Any help/suggestion will be very useful.

**/dev/spidev1.0 is linked to /sys/bus/platform/drivers/spi\_qsd, how to get spidev ( driver for SPI1 to be linked to one of a device file).**

regards

We are connecting IOT connector board ( SPI Slave) to mangOH red WP76xx, for which I feel we need SPI1 master to be up and running . I am unable to get a device for spidev for SPI1 in legato up.

As per discussion, at [WP7702 using SPI](https://mangoh.discourse.group/t/wp7702-using-spi/1188/31), I was able to re-direct SPI2 to RPi connector using spidev, but we are interested to get SPI1 =\> IOT connector working.

I have installed sierra wireless R10.1, release greater then this seems to have an issue with updates.  
Any thoughts/help will be useful.

Able to fix the issue by setting the clk to 4.8Mhz and activating gpioPin2 (brings IoT card out of reset).
