[BUG]: Not reading EEPROM content in Bootable Imager Image

[FiSh3rWoLf]

What happened?

The embedded Raspberry Pi Imager doesn't read IMAGER_REPO_URL in bootloader EEPROM.
Imager look for rmem0 but has rmem4 instead.

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

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:
