Texas Instruments Hardware Support Layer (meta-tanowrt-hsl-ti)

meta-tanowrt-hsl-ti — TanoWrt hardware support layer (HSL) for the Texas Instruments (TI) SoC based boards.

Contents

This layer contains various parts (recipes, files, etc.) from the meta-arago and meta-processor-sdk OpenEmbedded layers.

Supported Boards

TanoWrt has demonstration support for some devices and development boards based on Texas Instruments SoC’s. All supported devices are listed in the table below.

Table 23 Supported Texas Instruments Soc’s Based Boards

Board	SoC	RAM	Kernel Version	Supported Storage(s)	Target YAML (at kas/targets)
BeagleBone Black	Model: Texas Instruments AM3358 Cores: 1 x ARM Cortex-A8 Frequency: up to 1 GHz	512 MiB DDR3L	5.4.106 (RT)	4 GB eMMC	am335x-bbb-emmc.yml
				microSD card	am335x-bbb-sd.yml
AM3359 ICEv2 EVM (TMDSICE3359)	Model: Texas Instruments AM3359 Cores: 1 x ARM Cortex-A8 Frequency: up to 800 MHz	256 MiB DDR3	5.4.106 (RT)	microSD card	am335x-icev2-sd.yml
AM574x IDK EVM (TMDSIDK574)	Model: Texas Instruments AM5748 Cores: 2 x ARM Cortex-A15 Frequency: up to 1.5 GHz	2 GiB DDR3	4.19.94-rt39 (RT)	16 GB eMMC	am574x-idk-emmc.yml
				microSD card	am574x-idk-sd.yml

Configuration

Optionally you can customize some build options in local.conf configuration file (see Local Configuration section).

Kernel Version

Each of the supported machines can be built with one of the following kernels:

• 5.10.30 (TI staging RT kernel);

• 5.4.106 (TI staging RT kernel);

• 4.19.94-rt39 (RT kernel from TI Processor SDK Linux 06.03.00.106).

To choose the kernel version, you need to set variables TANOWRT_HSL_TI_SDK_KERNEL, TI_STAGING_KERNEL_VERSION and TANOWRT_WIREGUARD_IN_KERNEL in the local.conf (see Local Configuration section) file to determine which kernel should be used for the build.

The table below shows the values of the variables for choosing the required kernel version.

Kernel Version	TANOWRT_HSL_TI_SDK_KERNEL	TI_STAGING_KERNEL_VERSION	TANOWRT_WIREGUARD_IN_KERNEL
5.10.x	0	5.10	1
5.4.x	0	5.4	0
4.19.x	1	does not matter	0

Default kernel version used for each target are described in the table in Supported Boards section.

TI UIO Support

By default TI UIO support is disabled. To enable TI UIO support to build add this to your local.conf:

ENABLE_TI_UIO_DEVICES = "1"
TANOWRT_HSL_TI_SDK_KERNEL = "1"

Note

Currently this feature is supported only for kernel from TI Processor SDK (4.19). So you must also set TANOWRT_HSL_TI_SDK_KERNEL to 1 in the local.conf file.
