Hi! Currently i am trying to create an guix image which will boot on embedded imx6 arm32 board. Following the guix manual, i was able to create such an image. This involved adding a custom uboot version and a kernel with custom definition file. If flashed on an sdcard, the uboot runs and the kernel boots. However, early on boot (presumably on executing initrd.cpio.gz), an `record-abi-mismatch-error` is thrown and a guix recovery repl is opened

Unfortunatly i have absolutely no clue what the problem could be. Could it be that the image was compiled with a differnt guile version than executet on the image? Could this explain the abi mismatch in the `file-system` record? Googling for the error i found the following post on this mailing list: > https://lists.gnu.org/archive/html/help-guix/2023-02/msg00147.html Seems like Maxim Cournoyer had the same problem with a board with the same socc (imx6). Unfortunatly no followup. (I mailed him in private in case he come up with a solution. If so, i will document it here, so that the next unlucky soul running into this error can find the solution). I cross-compile the image on x64 with > guix build -f custom-board.scm --target=arm-linux-gnueabihf -v3 -c2 -M2 -K > --no-grafts where `custom-board.scm` is my image definition (i can share it if helpfull). Option `--no-grafts` is needed due to > https://issues.guix.gnu.org/66866 For tips on how to debug this issue further i would be very grateful. Feels like i am very close to a bootable image. -- Best regards Christoph
