Hi, I am trying to create a full system spk (with all parts) however I am struggling to create an spk the modem will accept. I am using “fwupdate download [spk file]” to download the spk… I’ve built my own legato.cwe using a sdef file → mksys → systocwe I then build my spk using > swicwe -c …/leaf-data/current/fx30-cat1-image/9999999\_9907152\_SWI9X07Y\_02.37.03.00\_00\_GENERIC\_002.095\_000-full.spk …/leaf-data/current/fx30-cat1-linux-image/linux.cwe legato.wp76xx.cwe -o full.wp76x.spk Am I doing this incorrectly? Am I including the incorrect images? The update fails with the bootloader… running fwupdate checkStatus gives ``` `Bad status (Bootloader failed), install not possible.` ``` PS. The reason for this is to aid the production process, but also to ensure the apps are part of the base legato image so that they cannot be removed… ---

Have you downloaded one by one by fwupdate to make sure those three images are good? ---

Having dug into this a little more… the problem seems to be with my legato.cwe file… As just trying to fwupdate that results in the same problem… I’ve created it as follows > systocwe wp76xx System.wp76xx.update \_build\_cwe\_wp76xx I can confirm that the System.wp76xx.update can be applied by itself successfully, but the generated legato.cwe cannot… How could I debug this? Or is there something obvious I am doing incorrectly… Thanks, Karl ---

I don’t use systocwe, instead i make the legato.cwe directly by “make wp76xx” in the legato source package ---

Hmm ok I could try that… that would require me changing default.sdef file would it not? systocwe should work though? should it not?.. by the way I am assuming systocwe is the same as systoimg? ---

why do you add parameter -d? Do you do it in leaf shell? Not sure if you need to do a clean build for “make clean” ---

yes I’m in leaf shell… the “-d” gives me debug output of the make process…otherwise I get a more cryptic error I tried “make clean”… no difference ---

Hi @jyijyi, I’ve followed your suggestion of re-purposing the wifi sdef file. The system builds fine… looking around the build output. The update files that are created in ./build/wp76xx/system/app/\* are they full update files? I ask because they are significantly different in size compared to update files created using mkapp of the same adef files?
