Awesome!

> Could you please let me know how to install local built ubuntu images

Sure, please follow these steps:

1. Download rootfs from
http://cdimage.ubuntu.com/ubuntu-base/releases/20.04/release/ubuntu-base-20.04-base-armhf.tar.gz

2. Extract it wherever you want yours root to be, like ExternalSD card
or eMMC /data partition or even NFS directory if you'll use usbnet.

3. Clone this kernel https://github.com/grate-driver/linux which is a
recent upstream linux-next + work-in-progress patches that haven't been
merged into upstream yet. For example DRM bridges and Tegra Partition
Table patches are under review now.

4. Select tegra_defconfig:

	ARCH=arm make tegra_defconfig

5. Compile kernel:

	ARCH=arm make

6. Append DTB to zImage:

	cat arch/arm/boot/zImage
arch/arm/boot/dts/tegra20-acer-a500-picasso.dtb > arch/arm/boot/zImage-dtb

7. Turn on A500 and select 'fastboot' option in the bootloader's menu.

8. Boot compiled kernel:

	fastboot -c "root=/dev/mmcblk2p8 gpt tegraboot=sdmmc" boot
arch/arm/boot/zImage-dtb

9. Grab touchscreen/WiFi/Bluetooth firmware files from
https://github.com/digetx/linux-firmware

10. Grab ALSA UCM rule from https://github.com/digetx/alsa-ucm-conf

11. Enjoy!

Please let me know you'll experience any problems, I'll be glad to help.
