Bad partition size on apalis T30 during system upload

Dear Sir,
Im trying to upload linux system on apalis T30 using Apalis_T30_LinuxImageV2.6 with my custom rootfs. I have already changed EMMC_SIZE to: **EMMC_SIZE=$(expr 1024 \* 7450 \* 2 \* 2)** The problem which Im facing is that system is not probably loading completely. After runnig update.sh script I can see as follows:

Creating MBR file and do the partitioning
0+0 records in
0+0 records out
0 bytes copied, 0,000119793 s, 0,0 kB/s

Sector size (logical/physical): 512B/512B

Superblock backups stored on blocks:

but after system is loaded The final partition is to small:

rootfs          2,5G  2,4G     0 100% /
/dev/root       2,5G  2,4G     0 100% /
devtmpfs        997M     0  997M   0% /dev
tmpfs           200M  212K  200M   1% /run
tmpfs           5,0M     0  5,0M   0% /run/lock
tmpfs           399M     0  399M   0% /run/shm
tmpfs           399M  4,0K  399M   1% /tmp

How can I increase the rootfs partition on Apalis T30 before system copy?

I suspect that you are one of those customers trying to pre-load a huge root file system (whatever the reason for that may be). We actually did integrate this as part of our V2.7 beta 1 release with this, this and this and you may find more information about what exactly got changed in resp. git logs.

Dear Marcel,

My system is approx 2,5 GB so still below the limit. I made few tests end figured it out that setting up MIN_PARTITION_FREE_SIZE=600 resolving the problem. Don`t even have to change EMMC_SIZE.

Dear Kamil

Glad you got this sorted. Yes up to around 4 GB in size you should be fine. Beyond that you may need the fixes from our latest BSP.
