Hi @facundo.n.r ,
That’s good to hear! Booting in this way, do you have everything working well?
It is recommended to use a patch since you are trying to do changes into the kernel source code.
Best regards,
Daniel Morais
Hi @daniel_m.tx , how are you?
Finally I could create the image without using the patch, and using the same defconfig from layers/meta-toradex-bsp-common/recipes-kernel/linux/linux-toradex-mainline-git/defconfig.
But I don’t see the changes in the device tree. A file should appear in root@colibri-imx6ull-14938795:~# ls /dev/ called ttymxc2 which corresponds to UART3.
Can you help me with this?
This is my layer
meta-customer.tar (30 KB)
and the .dts for custom the device tree
/dts-v1/;
#include "imx6ull-colibri-wifi-eval-v3.dts"
/ {
model = "Toradex Colibri iMX6ULL 512MB on Colibri Evaluation Board V3";
compatible = "toradex,colibri-imx6ull-wifi-eval", "fsl,imx6ull";
};

Hi @facundo.n.r ,
Good to hear that you can create your image!
Can you check if you are flashing the correct device tree into the module? By default, since this module uses UBI, the dtb that is flashed into the module is defined on the image.json file.
You also can try to flash the .dtb directly using the userspace tool as explained here. Can you please try it just to confirm that your dtb is being flashed?
Also, please share with us the entire dmesg log.
Best regards,
Daniel Morais
Now I included the colibri-imx6ull.inc file in the folder meta-customer, customized it, and then compiled the image. Now my-devicetree.dtb is included in image.json. But there are still no changes in the module.
Hi @daniel_m.tx !
I check the image.jason file, and it does not include the my-devicetree.dtb.

Hi!! I was looking at antoher topic, (Update image.json file and adding a custom device tree during Yocto build - iMX6ULL BSP 6 - #6 by facundo.n.r) and following these step I can compiler.
But the device tree was isnt modification.
I share my meta-customer, and image.json

Hi @facundo.n.r ,
This issue seems quite strange. Can you please share with me what exactly you want to do with this new device tree? What changes are you expecting to make? So I can do some tests here and prepare what exactly you need to do on your side.
Best regards,
Daniel Morais
Hi! @daniel_m.tx ,
I want customized the device tree for adding an uart3, with the next code:
/dts-v1/;
#include "imx6ull-colibri-wifi-eval-v3.dts"
/ {
model = "Toradex Colibri iMX6ULL 512MB on Colibri Evaluation Board V3";
compatible = "toradex,colibri-imx6ull-wifi-eval", "fsl,imx6ull";
};
/*Creo un nodo uart3 para configurar los puertos*/
&pinctrl_gpio1{
/delete-property/ fsl,pins;
fsl,pins = <
MX6UL_PAD_JTAG_TCK__GPIO1_IO14 0x70a0 /* SODIMM 99 */
MX6UL_PAD_NAND_CE1_B__GPIO4_IO14 0x10b0 /* SODIMM 133 */
MX6UL_PAD_UART3_CTS_B__GPIO1_IO26 0x10b0 /* SODIMM 100 */
MX6UL_PAD_JTAG_TRST_B__GPIO1_IO15 0x70a0 /* SODIMM 102 */

MX6UL_PAD_UART3_RTS_B__GPIO1_IO27 0x10b0 /* SODIMM 186 */
>;
};
&uart3{
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_uart3>;
fsl,dte-mode;
status = "okay";
};
&iomuxc {

};

Hello @facundo.n.r ,
You should specify “my-devicetree.dtb” to an existing product id which currently are:
- 0036
- 0040
- 0044
- 0045
- 0062
Replace imx6ull-colibri-eval-v3.dtb and wifi variant with your device tree in colibri-imx6ull.inc and rebuild the image.

But there were no changes in the device tree
Hi @facundo.n.r ,
Thanks for sharing what exactly you want to achieve.
I did some tests with the layer you provided to enable the UART3, I will list how exactly I made the changes to help you in the future.
Firstly, I needed the kernel repository to make any changes there, to achieve this I executed the following commands:
yocto@8e4137a0b856:/workdir/bsp6/build$ bitbake virtual/kernel -e | grep ^S=
S="/workdir/bsp6/build/tmp/work-shared/colibri-imx6ull/kernel-source"
yocto@8e4137a0b856:/workdir/bsp6/build$ bitbake virtual/kernel -c patch
The first command will tell me where the source code is being deployed, the second command will ensure that my kernel repository will have all other patches applied by default.
Since you want to only enable the UART3, I chose to create a patch that changes the file imx6ull-colibri.dtsi. This file is a device tree that has all instructions for our SoM and will be inhered by all Carrier Boards’ device trees, for more information about the device tree structure please access this article. Below you can see the entire patch:

Having this patch generated inside the kernel repository, you only have to add it to our kernel recipe to have this applied to the final image, the final layer can be seen below:
.
├── conf
│ └── layer.conf
├── COPYING.MIT
├── README
└── recipes-kernel
└── linux
├── linux-toradex
│ └── colibri-imx6ull-enable-uart3.patch
└── linux-toradex-mainline_%.bbappend
The content of the linux-toradex-mainline_%.bbappend can be seen below:
FILESEXTRAPATHS:prepend := "${THISDIR}/linux-toradex:"
SRC_URI:append = "\
file://colibri-imx6ull-enable-uart3.patch \
"
You can also download the final layer below:
meta-customer.zip (3.8 KB)
These are the only changes I made to enable the UART3, after flashing the new image it is possible to see the device listed:
root@colibri-imx6ull-14683513:~# ls /dev/ttymxc*
/dev/ttymxc0 /dev/ttymxc1 /dev/ttymxc2 /dev/ttymxc4
Can you please do some tests on your side and let me know if you face any issues?
Best regards,
Daniel Morais
Thank you very much @daniel_m.tx, I appreciate it very much, this way works perfectly.
I have one more question
When creating this command
MX6UL_PAD_UART3_TX_DATA__UART3_DTE_RX 0x1b0b1 /* SODIMM 135 */
Where do you look up the parameters for the hexadecimal number 0x1b0b1? Because, in the colibri imx6ull datasheet, I only find the Pad Control Register.
Hi @facundo.n.r ,
Glad to hear that it worked!
You are looking into the right place! The Pad Control Register is defined into the 0x1b0b1, to understand it you have to convert from hexadecimal to binary and you will see all the bits enabled.
Best regards,
Daniel Morais
