Re: [beagleboard] DTS compiled on x86 Linux causes errors when dtbo is loaded?
I'm using a clone of the bb.overlay repo and just copied my DTS into the src/arm directory and did a make from the top.

[beagleboard] DTS compiled on x86 Linux causes errors when dtbo is loaded?
Should I be able to compile my dts file on my x86 Linux box and have it work on my Beaglebone Black ?? I would have thought so, but if I build the same DTS file on Ubuntu 16.10 (with the update to date DTC) and install the resulting dtbo on my Beagle Bone Black running Debian with the 4.4.54-ti-r93 kernel, I get all kinds of pinmux errors such as: 18.517928] bone-pinmux-helper ocp:P8_11_pinmux: could not find pctldev for node /ocp/l4_wkup@44c0/prcm@20/clocks/clkdiv32k_ick, deferring probe [ 18.518391] bone-pinmux-helper ocp:P8_12_pinmux: could not find pctldev for node /ocp/l4_wkup@44c0/prcm@20/clocks/gpio0_dbclk_mux_ck, deferring probe [ 18.518678] bone-pinmux-helper ocp:P8_13_pinmux: could not find pctldev for node /ocp/l4_wkup@44c0/prcm@20/clocks/stm_pmd_clock_mux_ck, deferring probe [ 18.518935] bone-pinmux-helper ocp:P8_14_pinmux: could not find pctldev for node /ocp/l4_wkup@44c0/prcm@20/clocks/virt_2500_ck, deferring probe [ 18.519176] bone-pinmux-helper ocp:P8_15_pinmux: could not find pctldev for node /ocp/mailbox@480C8000/wkup_m3, deferring probe [ 18.519468] bone-pinmux-helper ocp:P8_16_pinmux: could not find pctldev for node /ocp/l4_wkup@44c0/scm@21/dma-router@f90, deferring probe [ 18.519906] bone-pinmux-helper ocp:P8_09_pinmux: could not find pctldev for node /ocp/l4_wkup@44c0/prcm@20/clocks/dpll_per_m2_ck, deferring probe [ 18.520217] bone-pinmux-helper ocp:P8_10_pinmux: could not find pctldev for node /ocp/l4_wkup@44c0/prcm@20/clocks/clk_24mhz, deferring probe [ 18.582466] bone-pinmux-helper ocp:P8_11_pinmux: could not find pctldev for node /ocp/l4_wkup@44c0/prcm@20/clocks/clkdiv32k_ick, deferring probe [ 18.582920] bone-pinmux-helper ocp:P8_12_pinmux: could not find pctldev for node /ocp/l4_wkup@44c0/prcm@20/clocks/gpio0_dbclk_mux_ck, deferring probe [ 18.583203] bone-pinmux-helper ocp:P8_13_pinmux: could not find pctldev for node /ocp/l4_wkup@44c0/prcm@20/clocks/stm_pmd_clock_mux_ck, deferring probe [ 18.583455] bone-pinmux-helper ocp:P8_14_pinmux: could not find pctldev for node /ocp/l4_wkup@44c0/prcm@20/clocks/virt_2500_ck, deferring probe If I take the same dts with no changes and copy it over and compile it under Debian on my Beagle Bone Black and it install it, it loads fine with out errors. Does this make sense ??

[beagleboard] Enabling CAN and GPIOs at the same time.
We are using a Beaglebone Black rev-C and need to have both DCAN1 and some of the GPIOs enabled at the same time. So we've tried loading both the BB-CAN1-00A0 and the univ-emmc-00A0 overlays. That of course does not work since P9.24 and P9.26 conflict between the two. So I modified univ-emmc-00A0.dts to not configure P9.24 and P9.26. Both overlays load and the GPIOs work fine. But dcan1 does not. If I do not load univ-emmc-00A0 and only load BB-CAN1-00A0, dcan1 works great but I loose my GPIOs. CAN also does not work if I just load univ-emmc-00A0 and manually configure P9.24 and P9.26 to "can" using the config-pin script. (Not working means no data transferred when monitoring with a logic analyzer.) Since this is my first time with dts files, I must be missing something here.Any hints would be appreciated. --Charles Johnson -- DISCLAIMER: This email correspondence and any attachments may contain confidential and privileged information intended only for the use of the designated recipient(s) listed above and is the property of ZincFive, Inc.
