Hi, AllAbout the sdcard partition support on lava, As you all have already known, the mmcblk0p8 partition can not be recognized in the master image for iMX and origen boards. Also I have tried with my panda to mount the mmcblk0p8 as the sdcard, but because the 8th partition major number is different with others as following: root@linaro: cat proc/partitions major minor #blocks name 179 0 7830528 mmcblk0 179 1 53248 mmcblk0p1 179 2 991232 mmcblk0p2 179 3 65536 mmcblk0p3 179 4 1 mmcblk0p4 179 5 2097152 mmcblk0p5 179 6 2097152 mmcblk0p6 179 7 2097152 mmcblk0p7 259 0 420864 mmcblk0p8 root@linaro: the 8th partition cannot be used in android too. So at the point now for us the only way is to reduce the partition number of our sdcard. Here are 3 idea I have thought, but I don't which should we use: 1. merge the master boot partition and target boot partition as one partition Problem: the master boot partition will be modified each time the target is deployed. This will increase the risk to destroy the master boot 2. merge the master boot partition and master rootfs partition as one partition Problems: 1)we need to change to use the vfat file system format for rootfs, because the uboot need the vfat format 2)Need to change the master initrd.img and merge the two partitions in our lava-create-master script 3. merge the target boot partition and target rootfs partition as one partition Problems: 1)we need to change to use the vfat file system format for rootfs, because the uboot need the vfat format 2)this is not the default partition layout that target image will use, and will increase the failure risk in other thing. 4. leave the iMX and origen not supported until the sdmux
I think we should try this for now and maybe re-visit if it becomes a problem.
Any other ideas about how to deal with this problem?
