The Ethernet MAC address of the Acqua board is stored in an onboard
EEPROM. Its location is described in the device tree as:
eeprom@58 { // NVMEM node
// EEPROM parameters...
eth0_addr: eth-mac-addr@9A { // NVMEM cells
reg = <0x0 0x06>;
};
};
Since Linux 6.5, defining NVMEM cells this way, as direct children of
the NVMEM node, is deprecated. It is instead recommended to wrap the
cells inside a "fixed-layout" node.
The older, deprecated syntax is still supported on Linux 6.6. Since
Linux 6.7 (commit 2cc3b37f5b6d: "nvmem: add explicit config option to
read old syntax fixed OF cells") however, it is only supported by
selected NVMEM drivers. It is not supported by the at24 driver used to
access the Acqua's onboard EEPROM.
Update the device tree to the new, recommended, syntax. This makes it
work with newer kernels, while preserving compatibility with the
currently used 6.6.30.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
