U-boot does not detect correct r-car board variant

Affected images versions

any

Description

Apertis currently supports Renesas R-Car M3 Starter Kit Pro (M3SK/m3ulcb) and Renesas R-Car H3 Starter Kit Premier (H3SK/h3ulcb), however, u-boot is not able to detect the right variant and sets renesas/r8a7795-h3ulcb.dtb as default dtb causing m3 variant not to boot with default environment.

Reproducibility

How often the issue is hit when repeating the test and changing nothing (same device, same image, etc.)?

Put the ✅ in the most appropriate entry:

  1. ✅ always
  2. often, but not always
  3. rarely

Impact of bug

R-car M3 boards with default environment are not able to boot, however, after setting the proper environment setting they boot fine.

Attachments

Add further information about the environment in the form of attachments here. Attach plain text files from log output (from journalctl, systemctl, …) or long backtraces as attached files. If adding comments on the log is required create a new snippet and add the link to it here.

Screenshots and videos are usually useful for graphic issues.

Root cause

Not autodetection of r-car board variant

Outcomes

  • pkg/u-boot!97 (merged)
