Thanks. > As you might guess, I use ptxdist for building the BSP for an i.MX6 based How could I guess this? It's a pretty exotic proprietary environment after all.

You still don't explain which exact command you are running that produces the output? f you are running the default bootcmd secuemnce, it would make a lot of sense to run this sequence manually, step by step, so have an exact understanding of what is going on. It _looks_ to me as if you were running $boot_extlinux in the end, but it would be nice to be sure... > What actually works is using an extlinux.conf similar to the examples in doc/ > README.distro, but there are two things to mention: > > 1) keywords are used which are not mentioned in the upstream extlinux > documentation > 2) keywords from the bootloader spec don't work at all If you have a look at the code (in "cmd/pxe.c"), the following keywords are implemented: 864 /* 865 * Keywords recognized. 866 */ 867 static const struct token keywords[] = { 868 {"menu", T_MENU}, 869 {"title", T_TITLE}, 870 {"timeout", T_TIMEOUT}, 871 {"default", T_DEFAULT}, 872 {"prompt", T_PROMPT}, 873 {"label", T_LABEL}, 874 {"kernel", T_KERNEL}, 875 {"linux", T_LINUX}, 876 {"localboot", T_LOCALBOOT}, 877 {"append", T_APPEND}, 878 {"initrd", T_INITRD}, 879 {"include", T_INCLUDE}, 880 {"devicetree", T_FDT}, 881 {"fdt", T_FDT}, 882 {"devicetreedir", T_FDTDIR}, 883 {"fdtdir", T_FDTDIR}, 884 {"ontimeout", T_ONTIMEOUT,}, 885 {"ipappend", T_IPAPPEND,}, 886 {NULL, T_INVALID} 887 }; This does not fit with your description, as you list: > Ignoring unknown command: title > Ignoring unknown command: version > Ignoring unknown command: options > Ignoring unknown command: linux > Ignoring unknown command: devicetree OK, "version" and "options" are not implemented, but the other keywords are, so you must be doing something else wrong. > Neither does it support multiple files (just /boot/extlinux/extlinux.conf > works) nor the keywords specified? You can run the sysboot command as often with different data as you like, so what o you mean? > I have to add, I currently still use U-Boot 2016.09, but I did a thorough > research in master and the responsible code in cmd/pxe.c did not change from > a > functional point of view since 2016.09. That does not appear to make a difference in terms of the supported keywords.
