Title: Trouble getting resize2fs to work
Post by: Kagetaze on August 02, 2016, 08:32:20 AM: Hello everyone!

First time using Tiny Core on my Raspberry Pi and I'm loving the idea. Although I consider myself a somewhat seasoned Linux user, I'm having troubling wrapping my head around how this all works and I was hoping to get some pointers into the right direction.

That having said, I have a RPi 3 that I'm using with a 4GB MicroSD card. I installed piCore-8.0beta4 although Linux box 4.4.15-piCore_v7+ shows up in the description.

That said, I'm trying to install Python and wanting to have it be persistencly on my SD card so it loads while booting.

I found some tutorials, but each and every one of them doesn't seem to get me anywhere. I believe I need to allocate some RAM for it to be installed and loaded, but no real idea how to get there.

My df-a outputs:

As usual, read README >:(

Post by: Kagetaze on August 02, 2016, 10:32:18 AM: I'm terribly sorry. I did read the README, apparently not as thorough though. My next question is related to the original topic and getting the resizing to work:

In the README it says that I have to delete the 2nd partition and resize it so that it will enough space for additional programs. However, this logically doesn't make any sense for me:
Quote
1) Start fdisk partitioning tool as root:

sudo fdisk /dev/mmcblk0

Now list partitions with 'p' command and write down the starting and
ending cylinders of the second partition.

2) Delete second partition with 'd' than recreate it with 'n' command.
Use the same starting cylinder as deleted had and provide end
cylinder or size greater than deleted had having enough free space
for Mounted Mode. When finished, exit fdisk with 'w' command. Now
partition size increased but file system size is not yet changed.

Code: [Select]
Command (m for help): p Disk /dev/mmcblk0: 3881 MB, 3881828352 bytes 3 heads, 8 sectors/track, 315904 cylinders Units = cylinders of 24 * 512 = 12288 bytes Device Boot Start End Blocks Id System /dev/mmcblk0p1 342 2902 30720 c Win95 FAT32 (LBA) /dev/mmcblk0p2 1 341 4088 83 Linux
If I delete the 2nd partition (mmcblk0p2) I can only write 341 as the first partition starts from 342. This means I will never be able to create a bigger size? Am I missing something here?

Yes. Read README.

Creating a partition below 342 you are demaging boot.

Welcome. This is the normal piCore baptism! We have all been there.

BTW: piCore comes with micropython already installed.
