Troubleshooting .wic Image Flashing for Hailo-15H Rapid Development

General Discussion
1

Hi everyone,

I am currently working on a custom Yocto image for the Hailo-15H platform. I’ve been following the official Quick Start Guide, but I’m looking for a more efficient workflow for rapid development.

The Issue: The .wic file generated by the Yocto build system appears unresponsive when flashed to the SD card. I’ve noticed a discrepancy in the partition structure:

  • Quick Start Guide Method: Results in a single partition.

  • Yocto .wic Output: Generates two partitions (standard for many BSPs, but failing to boot here).

Questions:

  1. Flashing Process: What is the recommended method for flashing .wic images for the Hailo-15H? I am currently using dd (and have tried BalenaEtcher), but the board does not seem to recognize the boot partition.

  2. Rapid Development: Is it mandatory to follow the manual steps in the Quick Start Guide for every image change, or is there a way to automate the deployment of the .wic file?

  3. Partitioning: Does the Hailo-15H bootloader expect a specific partition UUID or a single-partition layout that the standard WIC kickstart (.wks) file might be misconfiguring?

Environment:

  • Target Hardware: Hailo-15H

  • Yocto Release: [Insert version, e.g., Scarthgap/Kirkstone]

  • Host OS: Ubuntu 22.04

Any insights into the WIC configuration or alternative rapid-flash methods for this specific SoC would be greatly appreciated.

Regards.
