Other Parts Discussed in Thread: TPS65217

Hi,

I am always getting this delta_v messages which are printed in the syslog file.

Is it necessary to print always this information?

How can quiet this message?

Best regards

    We are getting these messages as well.  As far as I can tell the the smart reflex info never changes.  How can we tell if this debug message is indicating a problem or not?  Should set_voltage() not be getting called this often?

    How can I quiet this message without rebuilding the kernel, assuming this is merely an informational debug message?


    Can we simply modify the kernel at set_voltage() function inside the <linux_dir>/arch/arm/mach-omap2/am33xx-smartreflex-class2.c file to not print these messages anymore?

    We are using a TPS65217 with the am3358-100.  There is only the one i2c interface on this PMIC, I believe.

    Hi James,

    James Chen3
    Would you kindly explain what the SR 1 error message stands for?  (SR 1: curr=1112500, delta_v=-3822, calc=1108678, act=1112500, gain=27).  Attached is the booting dmesg for your reference. Your reply will be highly appreciated.

    This is not an error message, but a SmartReflex debug message. It is generated inside the set_voltage() function inside the <linux_dir>/arch/arm/mach-omap2/am33xx-smartreflex-class2.c file.

    This function is used to change the voltage to a new value.

    Best regards,
    Miroslav
