thanks this is very helpful. I built the linux-next for my Duckbill and add the SSP2 section from imx28-evk.dts into imx28-duckbill.dts. Without my patch i get the following for HW_CLKCTRL_FRAC0: ./memwatch -a 0x800401B0 0x800401b0: 0x5e5b5513 With my patch i get: ./memwatch -a 0x800401B0 0x800401b0: 0x5e1b5513 So it looks like a problem in my patch.Yes, let's try to get the same value HW_CLKCTRL_FRAC0.quoted
I orded such a flash chip, but it will take some time until i can use it with my hardware.Thanks for doing this. Maybe if you find out a way to fix the calculation of HW_CLKCTRL_FRAC0, then I can test it on my board.Hi, the difference is this 0x40 bit, right ? That's _STABLE bit, so it means the clock are not stable, right ? Why would that happen in the first place?
Can you dump all the registers related to all of the clocks provided by your clock driver, both with and without your patch? Then just diff them. Might be more deltas than just this one register. Regards, Mike
