Hi all,

if i have done the processing and loaded the file through mender steps. loaded that image into the BBB. so at starting time image size was 4GB and its running in the client(BBB).  
While doing FOTA process my image size is 16GB so how mender or partition of client will handle a new image.  
will it work or i need to do any changes?

Hi @Anil9860 the storage size is declared in the configs/beaglebone\* files using the variable name MENDER\_STORAGE\_TOTAL\_SIZE\_MB. For SDCard it defaults to 8192MB and for eMMC it is 3648MB.

Note that eMMC size is limited by your hardware. I’m not sure if there are options of different eMMC sizes or if they are all 3648 which is what my board has.

You can edit those files directly to change the amount of space. Note that number is the total amount of space, accounting for all the partitions. See [https://docs.mender.io/2.1/devices/yocto-project/partition-configuration](https://docs.mender.io/2.1/devices/yocto-project/partition-configuration) for more details.

Also, you cannot change the partition size in an OTA update. If you need to change the partition sizes, you need to reprovision your board using SDIMG file directly.

HTH,  
Drew

hi @drewmoseley,

1. I changed the MENDER\_STORAGE\_TOTAL\_SIZE\_MB=“16384” like this, and after that i followed the steps of artifact and took the .mender image and i am trying to deploy by demo server bu getting an error

can you tell me why its happening?

1. I can’t change the partition, and how to do the re-provision board using SDIMG file i don’t know.  
can you tell me how to do this?

Anil.

yes i have done successfully after changing the MENDER\_STORAGE\_TOTAL\_SIZE\_MB=“16384” on both side. means firstly i changed at client side and then i deployed the FOTA file from demo server. FOTA successfully done.

Thanks @drewmoseley
