Feedback (not requested) for WIP images for unsupported board (Orange Pi 2G-IOT)

[ignios]

Hi there i just receive this promissing board. I update the armbian build tree and it appears on WIP. I tried to build the image but it fails on kernel building (a missing .config file), how can i help you to quick test the board?

fail on boot after with WIP image

its no ext2 partitionon on sd card so uboot cant find boot.scr ,its  on ext4 partition in /boot

[Orange Guy]

after today commits infinite boot loop 
after Started Load Kernel Modules.

I am using armbian wip config to build .

 

Please correct me and guide. ignore if it sound no sense.

 

uboot and kernel able to find both on board stoarge and sd card ( evo 16gb) . find below given boot and dmesg snippet.

RDA8810 has in built toshiba slc 1.8v nand . RDA8810 kerenel needs the patch for 3.10.62 

I am learning to hack and not sure how to patch for 3.10.62.

There is an armbian work for this board i have use it and do a version img for this board (unestable but usefull):

I have compile armbian for opi 2g, only for test:

 Thanks to the help of the community We have managed to activate the NAND in linux and now the partitions denoted to Android are shown like this:

 

Disk /dev/mtdblock0: 24 MiB, 25165824 bytes, 49152 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

[................................
..................................]

Disk /dev/mtdblock4: 280 MiB, 293601280 bytes, 573440 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

I have compiled armbian community version (WIP) for Opi IoT 2G, I would like to know if it is possible to install armbian in NAND memory.

We have a total of 512MB of NAND, it is little but I think enough to incorporate a small Linux distribution (eg armbian) .

I have seen that the armbian script to install on the NAND (nand-sata-install.sh) looks in /dev/nand, but the IoT 2G Opi does not have this device. Is it possible

to remove the NAND disk (in Disk /dev/mtdblock0...4) from this card and create a /dev/nand device of 512mb?
Thank you

We are already a few users of this board. We believe that it already has enough potential for support. I myself have managed to install armbian W.I.P, community on the 512mb of NAND of this card and works well.

Thanks
