Fdisk, resize the root partition #91

Open PJ5168 opened 5 months ago

PJ5168 commented 5 months ago

Device : Pico Max SD : TF SanDisk Ultra 32GB OS Image : Official Ubuntu SD Issue : The lsblk can see all the partitions on the SD, but fdisk, resize2fs, and parted can not. How to resize the root file system? Thanks!

lsblk

fdisk /dev/mmcblk1

Welcome to fdisk (util-linux 2.37.2). Changes will remain in memory only, until you decide to write them. Be careful before using the write command. This disk is currently in use - repartitioning is probably a bad idea. It's recommended to umount all file systems, and swapoff all swap partitions on this disk.

Device does not contain a recognized partition table. Created a new DOS disklabel with disk identifier 0x26702e50.

resize2fs /dev/mmcblk1

resize2fs 1.46.5 (30-Dec-2021) resize2fs: Device or resource busy while trying to open /dev/mmcblk1 Couldn't find valid filesystem superblock.

parted

We have not tested this. Usually we modify the partition directly in the MK file of the SDK.

Meanwhile, for 32B TF, the root is 6GB, the rest is 22.9GB on p8 but not mounted. So, for different size of TF, have to build a new image?

PJ5168 commented 5 months ago

BTW, can not mount nor format the p8 partition.

BTW, checked with Milk-V Duo, the lsblk and fdisk work.

I would also be intrested in a way to resize the root partition of the image. fdisk/parted and the like will most likely never work as the sd card does not use a normal partition table. As far as I could see the env.img contains the sizes. and is on the first 32k of the sd card. I have edited this file to change the root partition form 6 to 7GB but then the chip complains (via UART) about a checksum error and doesnt boot anymore. I presume that the 32K env.img has a checksum somewhere inside of it.

I sadly cannot use SOC toolkit at all since the images created by it did never boot at all. I manually "glued" all .img files together with the help of another user and then used dd to put it onto the sd card. This worked perfectly but I am now stuck with a 6GB root partition. While this is unfortunate, its not a dealbreaker for me, as for my use case 6GB is probably enough.

I'm also couldn't resize root partition. But after changing export RK_PARTITION_CMD_IN_ENV="32K(env),512K@32K(idblock),256K(uboot),32M(boot),512M(oem),256M(userdata),6G(rootfs),-(media)" to export RK_PARTITION_CMD_IN_ENV="32K(env),512K@32K(idblock),256K(uboot),32M(boot),512M(oem),256M(userdata),32G(rootfs),-(media)" in project/cfg/BoardConfig_IPC/BoardConfig-***.mk config file root partition was fit to all free space on sd card after build and flush firmware using SocToolKit. Ubuntu, Pico Max.

I used this partition as SWAP space, are there any problems?

With this change, pip is now working.

mkfs.ext4 /dev/mmcblk1p8 did the job for me. Then you just mount it.
