Making an Allwinner SD card manually?
« on: March 02, 2016, 02:40:12 PM »
Hello people, I recently decided to try getting SD card booting to work on my tablet (Pendo Pad PP4MT-7, uses the A10)

I know how one is supposed to partition the SD correctly and install uBoot, but... how am I supposed to put the boot files on it?

I would use the tool for making pre-made SDs, but I don't have a tinycore system to do so. if however, this is the road to take, I'll see if a virtual machine will do the job.

Below were the steps I used to install TinyCore 5.4 on my MK802ii

$ wget newbielink:http://distro.ibiblio.org/tinycorelinux/5.x/armv7/Allwinner-A10/mksdcard.tgz [nonactive]
$ tar xzf mksdcard.tgz
$ cd sdcard/
$ ./mkSDcard.sh

mkSDcard.sh will ask you to enter the SD card (mmcblk0 in my case - 8 GB)

PS : I made some changes in mkSDcard.sh to suit some of my needs :D

Well, in my case, I wouldn't mind getting a bit of help with modifying the script to work with dCore then.

Or... being able to do everything, including partitioning the card, manually. (That way, i know exactly which script.bin and other files were used) The furtherest I got was getting the screen of my tab to turn on via the manual method. (good sign, probably means the SD was properly built with the right script.bin, but had no kernel installed. I got the script.bin from my tab's first NAND partition using android)

Have you tried to run other sd card images ie. debian, ubuntu on your tablet? Then from the image you probably could install and run the script.
