I'm running L4T 32.x version of L4T. I tried to run the flash-partitions.sh and it did flash various partitions, but I don't see any spidev messages in the kernel startup nor are there any /dev/spi devices.

I then tried to convert the DTB files in this repo to DTS files and looked through them. I see the additions to the SPI devices. Here is an excerpt from it:
`
spi@7000d400 {
compatible = "nvidia,tegra210-spi";
reg = <0x0 0x7000d400 0x0 0x200>;
interrupts = <0x0 0x3b 0x4>;
iommus = <0x2b 0xe>;
#address-cells = <0x1>;
#size-cells = <0x0>;
dmas = <0x4c 0xf 0x4c 0xf>;
dma-names = "rx", "tx";
nvidia,clk-parents = "pll_p", "clk_m";
clocks = <0x21 0x29 0x21 0xf3 0x21 0xe9>;
clock-names = "spi", "pll_p", "clk_m";
resets = <0x21 0x29>;
reset-names = "spi";
status = "okay";
num-cs = <0x2>;
cs-gpios = <0x56 0x13 0x1 0x56 0x14 0x1>;
linux,phandle = <0x10b>;
phandle = <0x10b>;

	prod-settings {
		#prod-cells = <0x3>;

		prod {
			prod = <0x4 0xfff 0x0>;
		};

		prod_c_flash {
			status = "disabled";
			prod = <0x4 0x3f 0x7>;
		};

		prod_c_loop {
			status = "disabled";
			prod = <0x4 0xfff 0x44b>;
		};
	};

	spi@0 {
		#address-cells = <0x1>;
		#size-cells = <0x0>;
		compatible = "spidev";
		status = "okay";
		reg = <0x0>;
		spi-max-frequency = <0x3dfd240>;

		controller-data {
			nvidia,cs-setup-clk-count = <0x1e>;
			nvidia,cs-hold-clk-count = <0x1e>;
			nvidia,rx-clk-tap-delay = <0x1f>;
			nvidia,tx-clk-tap-delay = <0x0>;
		};
	};

	spi@1 {
		#address-cells = <0x1>;
		#size-cells = <0x0>;
		compatible = "spidev";
		status = "okay";
		reg = <0x1>;
		spi-max-frequency = <0x3dfd240>;

		controller-data {
			nvidia,cs-setup-clk-count = <0x1e>;
			nvidia,cs-hold-clk-count = <0x1e>;
			nvidia,rx-clk-tap-delay = <0x1f>;
			nvidia,tx-clk-tap-delay = <0x0>;
		};
	};
};

But when the Nano boots, I don't see anything additional spi devices in the /proc/devicetree. For example, here is what is in /proc/device-tree/spi@7000d400:
nlbutts@jetson:/proc/device-tree/spi@7000d400$ ls '#address-cells' clocks dma-names interrupts linux,phandle nvidia,clk-parents prod-settings reset-names '#size-cells' clock-names compatible dmas iommus name phandle reg resets status

I've tried to manually insmod spidev, but that doesn't work either. Any ideas?

tegwyn@tegwyn:~$ cd /home/tegwyn/flash-dtb-update-2019-12-09 && sudo ./flashme.sh /dev/mmcblk0
[sudo] password for tegwyn:

flashme.sh: FAILED
md5sum: WARNING: 1 computed checksum did NOT match
tegwyn@tegwyn:~/flash-dtb-update-2019-12-09$

Following the instructions given to the repo, I cloned it to my machine. There's no flashme.sh file in the root directory, but there is one in the /flash directory. However, when I try to execute it, I get the following error:

md5sum: ./hash.md5: No such file or directory
One or more files are corrupt or missing.

md5sum: ./hash.md5: No such file or directory

I'm running JetPack 4.2, if it is of any substance to the issue.

Hi there! The patches are pretty awesome and work great, but I can't find any license in the repository, so it's practically impossible to use for other public projects. Do you have any plans to release these files under an open source license? 🙃

Thanks.
