Hi igor,
Thank you for your answer and your link, it's very good for a beginner in embedded linux & Yocto !
I use var-som-solo with the board VAR-SOLOCustomBoard. Both from variscite : VAR-SOM-SOLO/DUAL : NXP/Freescale iMX6 Solo / Dual Lite | Variscite
I worked well on it with your link and I have some questions :
- If i understand documents, the uboot is a bootloader which allow to initialize the var-som-solo during the boot and the device tree is also use during the boot but it allow to found the material caracterisque from var-som-solo ? It's correct ?
- For my device trees, the organization is the following :
imx6dl-var-som-vsc.dts ---------------> imx6dl-var-som.dtsi
---------------> imx6qdl-var-solocb-dt6cb-displays.dtsi
---------------> imx6qdl-var-solocb-dt6cb-buttons.dtsi
---------------> imx6qdl-var-solocb-misc.dtsi
|----------------> imx6dl.dtsi
|--------------------> dt-bindings/gpio/gpio.h
|--------------------> dt-bindings/input/input.h
|----------------> imx6qdl-var-som.dtsi
|--------------------> imx6q-pinfunc.h
|--------------------> imx6qdl.dtsi
|--------------------> dt-bindings/interrupt-controller/irq.h
|-----------------------> skeleton.dtsi
|-----------------------> dt-bindings/clock/imx6qdl-clock.h
|-----------------------> dt-bindings/input/input.h
|-----------------------> dt-bindings/interrupt-controller/arm-gic.h
it's normal that it's different from you ?
- If i want my custom dts, and change the name of the file during the command install_yocto.sh, how to process ? Because, if the file to flash NAND is imx6dl-var-som-vsc.dts and i want that it to be imx6dl-var-som-Maxime.dts for example, how to proceed ?
- If i understand, if i want to custom my customboard, i only change imx6dl-var-som-vsc.dts and imx6dl-var-som.dtsi ? If i want to custom my soc, i change the rest ?
So, if i want custom my var-som-solo to add GPT_Capture1, in the file imx6qdl-var-som.dtsi i add :
pinctrl_gpt_input_capture0: gptinputcapture0grp {
fsl,pins = <
MX6QDL_PAD_SD1_DAT0__GPT_CAPTURE1 0x1b0b0
>;
};
before
pinctrl_usdhc1_1: usdhc1grp {
fsl,pins = <
MX6QDL_PAD_SD1_CMD__SD1_CMD 0x17071
MX6QDL_PAD_SD1_CLK__SD1_CLK 0x10071
MX6QDL_PAD_SD1_DAT0__SD1_DATA0 0x17071
MX6QDL_PAD_SD1_DAT1__SD1_DATA1 0x17071
MX6QDL_PAD_SD1_DAT2__SD1_DATA2 0x17071
MX6QDL_PAD_SD1_DAT3__SD1_DATA3 0x17071
>;
};
then i disable &usdhc1
&usdhc1 { /* uSDHC1, eMMC */
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_usdhc1_1>;
non-removable;
keep-power-in-suspend;
enable-sdio-wakeup;
status = "okay"; >>>> status = "disable";
};
then i copy/paste the patch (time.patch.zip) from https://community.nxp.com/thread/492843 into time.c and it's ok ? i rebuilt my dts, i flash my NAND et i can read frequency on GPT_CAPTURE1 ?
- For my uboot, i have not the same directories that you :
with the example mx6q_4x_mt41j128.cfg is in build_12/tmp/work/var-som-mx6-fslc-linux-gnueabi/u-boot-fw-utils/1.0r0/git/board/freescale/mx6sabresd/mx6q_4x_mt41j128.cfg and not in board/freescale/imx/ddr/mx6q_4x_mt41j128.cfg
with the example mx6sabresd.c is in build_12/tmp/work/var-som-mx6-fslc-linux-gnueabi/u-boot-fw-utils/1.0r0/git/board/freescale/mx6sabresd/mx6sabresd.c and not in board/freescale/imx/ddr/mx6sabresd.c
the same with mx6sabre_common.h and mx6sabresd.h which are in build_12/tmp/work/var-som-mx6-fslc-linux-gnueabi/u-boot-fw-utils/1.0r0/git/board/freescale/include/configs/....
For my board i don't found that... Only mx6var_som.c in build_x12/tmp/work/var_som_mx6-fslc-linux-gnueabi/u-boot-fw-utils/1.0-r0/git/board/variscite/mx6var_som/mx6var-som.c and mx6var-som.h in build_x12/tmp/work/var_som_mx6-fslc-linux-gnueabi/u-boot-fw-utils/1.0-r0/git/include/configs/mx6var-som.h. I don't have common.h and cfg... But there is mx6_common.h but i don't know if it has relation between.
And file with vardl and var-solo are into mx6sabreauto and this, is not my board.. So i don't know where search..
Thank you for your answer.
Best Regards,
Maxime.
