1.8.5 (Default)

What host operating system were you using?

Windows

Host OS Version

23H2

Selected OS

Raspberry Pi Imager from HTTP Boot (downloaded https://fw-download-alias1.raspberrypi.com/net_install/boot.img on local server)

Which Raspberry Pi Device are you using?

Raspberry Pi 5

What kind of storage device are you using?

NVMe SSD via Third-party PCIe attachment

OS Customisation

  • Yes, I was using OS Customisation when the bug occurred.

Thanks for the report, @FiSh3rWoLf, and for the pre-submission sleuthing.

Curious we've not seen this one before. I'll need to check if this is specific to Raspberry Pi 5, or if it also affects the Raspberry Pi 4 family.

Applications need to use the blconfig alias and not hardcoded the rmem node

I can confirm that I'm hitting the same issue.

  1. Original RPI Imager downloaded from the official location and served locally in my network
  2. IMAGER_REPO_URL configured and no GET request can be recorded for the specified file

Would be glad to hear about a projected timeline for a resolution.
As a workaround, I will experiment, patching the URL I need into rpi-imager and serve that to my Raspberry Pi 5.

Please see the following context:
boot.conf file of the bootloader:
