Does the `lefwkro` partition only contain the Legato Framework? I mean by that, does it not contain any of the application code we’ve written? ---

When you download application to it by .update, it will install in userapp partition ---

And when the application is bundled with the framework as the output of `mksys` and `systocwe`, is all of it written in lefwkro or are the apps written into `userapp`? ---

for the application embedded in legato.cwe, it will be installed in /mnt/legato which is the lefwkro partition ---

thanks ok. So if we never use `update`, the userapp partition is never used? ---

> Btw, what is the relationship of at!partition to current issue? The current issue is that mtd14 is now too small after a bad block appeared. Increasing the size of the partition would allow to have a bad block and still have enough space for legato Alternatively, is there a way to increase the compression of squashfs when building legato? ---

Do you expect it to remove bad block? It has been marked bad by the `fwupdate` process after failing to write or erase the block. Is that a known issue? ---

Is it possible to apply compression to the legato image when using systocwe? I’ve been saving space where I could (using `-s` with systocwe saved significant space), but now I think the squashfs compression is likely the next best way to reduce the size. ![image](https://us1.discourse-cdn.com/flex019/uploads/legato1/original/2X/e/eadf981bb391e6423853e3debe754adc4d061282.png) Here I see compress is set to 0. Do you have some documentation on how to improve the compression? ---

Reducing the size of the legato system allowed to recover the unit. In conclusion to this issue: - Our legato system (including apps) was fitting the partition, but the first bad block declared in the memory led to not having enough space for it - Although that unit cannot be recovered without flashing over USB, reducing the size of the legato system should allow to prevent the problem in further updates (bad blocks are declared during updates, when the partition is erased then written again) - One of the simplest way to gain space was to strip the binary when building with `systocwe`, using the `-s` parameter - For our application, the partition can now have up to 7 bad blocks and still have enough space for the firmware (instead of 0) Here are useful commands to monitor the states of the bad blocks in the memory: `cat /proc/mtd` lists the partitions and their name `mtdinfo -M /dev/mtd14` shows the details of mtd14 partition including any bad blocks [Previous page](https://forum.legato.io/t/legato-not-installed-using-fwupdate/6553.md?page=1)
