[Discuss-gnuradio] How to change SPI clock rate on USRP2?

[Sriharsha Puranik]

Hi all,

Is there a way to change the SPI clock rate on USRP2? (I am using uhd)

I found a similar question for E100 here - http://comments.gmane.org/gmane.comp.hardware.usrp.e100/1257 . Is this solution applicable to USRP2 also?

Also, I found some variable in - /firmware/zpu/lib/spi.c "spi_regs->div = 1;  // 0 = Div by 2 (25 MHz); 1 = Div-by-4 (12.5 MHz)" Can I increase the value to 2? Will that make the clock speed 6.25 MHz?

Thanks,

Sriharsha Puranik.
