SPI Minimum Speed


#1

I am unable to get the SPI speed to go below 1Mhz on Linaro Linux 4.4.

I have found using spidev_test.c that any speed below 1Mhz causes the SPI speed to default to 1Mhz (verified with a scope and consistent with this post: [OE] Mix/Max SPI clock ranges?)

Is there any way to reduce the clock speed of SPI on the DB410c? Is there perhaps a clock divider register I can set?
