Hi
I appreciate your quick suggestions. Your thoughtful contributions are greatly valued.
I’ll start from scratch and will try the same.
Does a new fix/version (5.10.131-bone-rt-r64) available in the mainline bb-kernel?
Thanks & Regards,
5.10.131-bone-rt-r64 is the top of this branch:

Hi
Thank you for providing the kernel details, will try to build from the same.
I have installed bb.io-kernel-5.10-bone-rt and below are the results after rebooting the board,

Kindly provide your input.
Thanks & Regards,
at this point, i would just say the overlay BB-AAIM-LCD-00A1.dts is broken…
What model/etc is on the screen, where i can order one to test it?
Regards,
Hi
I agree, there is some difference in the dtbs
I have below information on frame buffer device info
On 16.04 – working Good

On Ubuntu 20.04 – not working

currently model details not available with me.
Thanks & Regards,
Well this 24 bit overlay works:
please compare with your overlay…
Since i can’t get the hardware, i can’t personally test it for your.
Regards,
Thanks for sharing the dts. I could not see the BB-BONE-NH7C-01-A0.dts file in the previous bb.overlays which were used on 16.04. is this new?
Also, I found previous dts do not include backlight section and below settings differ
previous dts – working on ubuntu 16.04
bb_lcd_pwm_backlight_pins: pinmux_bb_lcd_pwm_backlight_pins {
pinctrl-single,pins = <
BONE_P9_14 (PIN_OUTPUT_PULLUP | MUX_MODE7) /* gpmc_a2.ehrpwm1a */
>;
};
current one –
bb_lcd_pwm_backlight_pins: pinmux_bb_lcd_pwm_backlight_pins {
pinctrl-single,pins = <
AM33XX_PADCONF(AM335X_PIN_GPMC_A2, PIN_OUTPUT_PULLDOWN, MUX_MODE6) /* P9_14: gpmc_a2.ehrpwm1a */
>;
};
Above are the observations. I will try to get the LCD model details.
Thanks & Regards,
Starting in v5.4.x era, the base bb.org-overlays repo became un-usable, as upstream kernel started making struct level of changes inside the device tree. Thus we transitioned to kernel specific overlays, and back ported this into our v4.19.x-ti tree… Going forward, we have kernel specific overlays for now on…
For example for the v5.10.x based kernel we are in dissucion with, the main device tree are here:
and then matching overlays are here:
Regards,
Thanks for providing the information. I guess, the BB-BONE-NH7C-01-A0 lcd is connected to beaglebonegreen-gateway, But I am using BeagleBoneGreen. Do we have any hardware/connection difference between both boards?
I followed the below instructions to compile dtbs on 5.10.x kernel…
Step 1: Clone this repo:
git clone https://github.com/beagleboard/bb.org-overlays
cd ./bb.org-overlays
Step 2: Install *.dtbo:
./install.sh
Please correct me if am wrong.
Thanks & Regards,
That is not correct for 5.10.131-bone-rt-r64, use this repo.
git clone -b v5.10.x https://github.com/beagleboard/BeagleBoard-DeviceTrees.git
cd ./BeagleBoard-DeviceTrees/
make
sudo make install
Regards,
Hi
Thank you Robert for sharing the correct path. I will try the same.
Here are the LCD model details - Model No.TM101JDHP01.
Thanks & Regards,
When searching for that part number, it’s a LVDS panel, you must have an adapter board.
Unless the device is publicly available somewhere, it’s up to you to debug it.
Regards,
Okay, Attached is the datasheet for your reference.
I have compiled kernel 5.10.131.x and built the ubuntu LTS rootfs using image-builder. Now trying to integrate dtb files. I have compiled dtbs using BeagleBoard-DeviceTrees-5.10.x.zip overlays. After successful installation, I could see the below messages in the boot log. It seems like failed to load U-Boot overlays.

i’d fully expect those issues…
First error…
uboot_overlays: unable to find [mmc 0:1 /boot/dtbs/5.10.131-bone-rt-r64/overlays/BB-AAIM-LCD-00A1.dtbo]...
Looking at https://github.com/beagleboard/BeagleBoard-DeviceTrees/tree/v5.10.x/src/arm/overlays we see no BB-AAIM-LCD-00A1.dts file… So it doesn’t exist… Did you write one?
uboot_overlays: unable to find [mmc 0:1 /lib/firmware/BB-UART2-00A0.dtbo]...
uboot_overlays: unable to find [mmc 0:1 /lib/firmware/BB-UART4-00A0.dtbo]...
uboot_overlays: unable to find [mmc 0:1 /lib/firmware/BB-I2C1-00A0.dtbo]...
I need to migrate these over from the other project:
uboot_overlay_addr0=/boot/dtbs/5.10.131-bone-rt-r64/overlays/BB-AAIM-LCD-00A1.dtbo
#uboot_overlay_addr0=/lib/firmware/BB-UART1-00A0.dtbo
#uboot_overlay_addr1=/lib/firmware/BB-UART2-00A0.dtbo
#uboot_overlay_addr2=/lib/firmware/BB-UART4-00A0.dtbo
#uboot_overlay_addr3=/lib/firmware/BB-AAIM-LCD-00A1.dtbo
#uboot_overlay_addr4=/lib/firmware/BB-I2C1-00A0.dtbo
You don’t need /boot/dtbs/5.10.131-bone-rt-r64/overlays/ or /lib/firmware/ in any of these, u-boot knows how to look for them…
uboot_overlay_addr0=BB-AAIM-LCD-00A1.dtbo
#uboot_overlay_addr0=BB-UART1-00A0.dtbo
#uboot_overlay_addr1=BB-UART2-00A0.dtbo
#uboot_overlay_addr2=BB-UART4-00A0.dtbo
#uboot_overlay_addr3=BB-AAIM-LCD-00A1.dtbo
#uboot_overlay_addr4=BB-I2C1-00A0.dtbo
Sorry, the am335x does not support lvds, thus there is something on your design that adapts the RGB signalling form the am335x to the lvds.
Sorry, without access to public hardware there is nothing i can do…

Yes, I have integrated the one which was compiled with 5.4.x kernel. so copied dtbo under /boot/dtbs/5.10.131-bone-rt-r64/overlays/
ubuntu@arm:~$ ls -al /boot/dtbs/5.10.131-bone-rt-r64/overlays/BB-AAIM-LCD-00A1.dtbo

What steps we need to follow to migrate those dtbs? Please provide the guidelines.
Thanks & Regards,
From with-in the Device Tree git project:
make
sudo make install
Would place the *.dtbo’s in the location…
from u-boot try:
ls mmc 0:1 /boot/dtbs/5.10.131-bone-rt-r64/overlays/
Regards,
I copied .dtbo file to src/arm/overlays and then ran make install…

Oh, that’s fun to debug!..
First thing i’d do… Delete all data off the eMMC… i bet we have two different ext4 partitions that u-boot is reading from… So make sure only the microSD is being used…
Regards,
Yes, I have erased first few blocks of eMMC… so whenever sd card is not present i see CCCCCC…on the serial log.
I am using MLO and u-boot.img for u-boot version 2021 and not u-boot-dtb.img. would that causing any issue?
Thanks & Regards,
Hi
Thanks a lot for sharing the kernel 5.10.131 for BBG. I have figured out the issue and seems like tilcdc driver has been modified for different revision supports. I have added fix and verifying the changes. Currently, modifications are under test.
I would like to understand/explore the framebuffer device information details, As I mentioned earlier in one of the comments, I am having below data for framebuffer device
Frame buffer device information:
Name : tilcdcdrmfb
Address : 0
Size : 2048000
Type : PACKED PIXELS
Visual : TRUECOLOR
XPanStep : 1
YPanStep : 1
YWrapStep : 0
LineLength : 2560
Accelerator : No
I could see Address is always zero and size is also different. Could you please guide me to understand the parameters?
Thanks & Regards,
