Repositories and Pre-built Images¶
This page provides links to MitySOM-AM62x specific software and prebuilt images to support using the MitySOM-AM62x development kit.
Source Code Repositories¶
The following are links to the repositories that Critical Link provides for the kernel, U-Boot, Yocto, and FPGA sample projects.
SDK 10.x scarthgap (AM62x/AM62Ax)¶
| Type | Repo | Branch | Notes |
| Kernel | linux-kernel | mitysom-linux-6.6.y | Tracks TI's ti-linux-6.6.y |
| U-Boot | u-boot | mitysom-u-boot-2024.04 | Tracks TI's uBoot implementation |
| Yocto Top Level / Setup | oe-layersetup | criticallink | Adds Critical Link supplied Meta Layers to TI's PROCESSOR_SDK |
| Yocto Layer | meta-mitysom | scarthgap | Critical Link SOM Support Recipes |
Pre-Built SD-Card Images for the Development Kit¶
Note: The SD-Card Image requires a 16GB or larger Micro-SD card.
MitySOM-AM62x Development Kit SD Card Image¶
The following is a link to the latest released pre-built binaries for the MitySOM-AM62x Development Kit SD card image for the SOM variants. It includes the complete A53 and R5 SPL and uBoot images as well as the root filesystem.
| Description | Location | Manifest | Based on TI Release | Toolchain | Release Notes |
| Reference Micro-SD card Image | By default, this image is for HS SOMs tisdk-default-image-mitysom-am62x-SDK10.00.07_3.rootfs-20241029213418.img.zip md5 | Manifest | 10.00.07 | gcc version 13.3.0 | Release Notes |
| For GP SOMs, the same image can be used if tiboot3-am62x-gp-evm.bin is renamed to tiboot3.bin. If you use the image on a GP SOM without renaming the file, the target will not boot and there will be no output to the console. |
MitySOM-AM62Ax Development Kit SD Card Image¶
The following is a link to the latest released pre-built binaries for the MitySOM-AM62Ax Development Kit SD card image. It includes the complete A53 and R5 SPL and uBoot images as well as the root filesystem.
| Description | Location | Manifest | Based on TI Release | Toolchain | Release Notes |
| Reference Micro-SD card Image | tisdk-edgeai-image-mitysom-am62ax-SDK10.00.00_2.rootfs-20241029214835.img.zip md5 | Manifest | 10.00.00 | gcc version 13.3.0 | Release Notes |
| tisdk-default-image-mitysom-am62ax-SDK10.00.00_2.rootfs-20241029213249.img.zip md5 | manifest |
Previous SD card image releases...
For flashing the Micro-SD card, we recommend using balenaEtcher .
Note: balenaEtcher versions > 1.17.0 have a bug where verification will fail when flashing a zipped image containing a bmap file. Version 1.17.0 works just fine. https://github.com/balena-io/etcher/issues/4079
Debian Image (Not typically needed)¶
In general, Critical Link recommends using the Yocto-based reference image for your development. TI, however, provides a Debian image as part of their Processor SDK . This image can be used with the MitySOM-AM62x devkit by:- Replacing the boot partition U-Boot files with files from the boot partition of our reference image.
- Replacing the kernel files contained in the
bootdirectory on therootpartition with the corresponding files in our reference image. - Copying the Critical Link kernel modules from our reference image root parition (under
/lib/modules) to/lib/modules.
As an example, the following table contains a direct link to a Debian SD card image for the MitySOM-AM62x devkit. This image assumes you are using a HS-FS processor.
| Description | Location | Based on TI Release |
| Reference Micro-SD card Image (DEBIAN) | By default, this image is for HS-FS SOMs TI Debian Bookworm Processor SDK 9.2 (>700MB, A 16GB OR LARGER SD CARD is required) | TI Processor SDK 9.2 |
If you have any problems with this image or if you have questions about using Debian for your custom application, please contact Critical Link for further assistance or post in our forums.
