piCore for the H3 boards - Orange Pi, Nano Pi etc.

The only way how to get the system messages during boot is to use the serial debug console, please find some COM, or USB one and connect to the board.

How did you wrote the bootloader to the eMMC? Which one you've used?

[nxtv2.0]

Ok i will try all zimage files i see.
I used the eMMC with armbian and it worked flawlessly, using the nand-sata-install command.
i just wrote the image.img file to the eMMC using dd as if it was just a micro-sd card

[nxtv2.0]

Understand that you used all three files from Rev2 folder, but I need to test all the  zImage files, including:
https://dl.dropboxusercontent.com/u/86461636/Rev1/zImage
https://dl.dropboxusercontent.com/u/86461636/zImage

Both don't work.

Can you please list the commands needed to install piCore to eMMC as i can't install it myself and am a complete noob.

[jgrulich]

Open the nand-sata-install.sh file form Armbian and look whole the installing process, it's well commented there.
Than you may modify it to work for you.

I tried , didn't understand anything from it.

Hello jgrulich,
Great. I have a NanoPi NEO running Armbian with kernel 4.7 (my UPnP audio player, usb out). What are the commands for unpack and pack the piCore uInitrd ?
Thanks.

[jgrulich]

I have piCore 8.0 with the 4.8.0-rc5 which works well for headless server applications.
To generate the image files like a uInitrd, uImage, etc. I'm using the mkimage utility.

But how to "unpack piCore initrd in a temp directory" ? (see initrd section in http://forum.tinycorelinux.net/index.php/topic,17895.0.html )
Could you place the link of your piCore 8.0 with the 4.8.0-rc5 image ?
Thanks.

But how to "unpack piCore initrd in a temp directory" ? (see initrd section in http://forum.tinycorelinux.net/index.php/topic,17895.0.html )

I found a solution: http://h-wrt.com/en/mini-how-to/uInitrd

[jgrulich]

Why to do it so complicated? Everything is nicely written in the Corebook:
http://tinycorelinux.net/book.html
When you don't know how to, than look there as a first resort.

I didn't find uInitrd, mkimage and uboot in the Corebook. Where the Corebook explain how to unpack uInitrd ? Thanks.

[bzfrp]

Thanks. I begin to understand. It is in chapter 11 of the Corebook.
initramfs is 8.0v7.gz and kernel is kernel4420v7.img

Ok i got piCore working from eMMC ,
I flashed image.img(i modified your's and added the rev2 files you sent for ethernet) to eMMC using dd command in armbian running on sd card, and then flashed the bootloader .bin file in armbian, this post explaines the bootloader part i did post #8.http://forum.armbian.com/index.php/topic/1070-install-to-emmc/

It booted with a lot of errors, how do i fix them, i need to speed up boot.
