06:53 <probono> hello. i am new to this whole linux-armlogic thing but first thing before i do anything is backup the entire content of the NAND of my box. so far i only found instructions on how to backup individual partitions, but i understand there is some things (e.g., the MAC address) in unpartitioned space on the NAND as well. how can I do a full bit-by-bit

06:53 <probono> copy of the entire NAND chip? i have a S802 with serial console access and USB OTG access

06:55 <probono> also, is the partitioning scheme hardcoded into the SOC or is it software-defined somewhere?

06:55 <chewitt> before you go further .. what are you hoping to do with the box?

06:57 <chewitt> because options with meson8* hardware are limited

08:29 <probono> Thinking of a print server for 3D printers and similar such tasks. My use case is already running well from SD card but I want to make a "real embedded system" :)

08:56 <chewitt> should be okay then

08:57 <chewitt> if it was anything graphical the lack of DRM driver would have been a challenge

09:47 <poulecaca> does anyone know what RTI acronym of the regions mapped in 0xc8100000 and 0xDA100000 of S905X memory stand for ?

11:32 <narmstrong> poulecaca: be creative

11:37 <poulecaca> run time interrupt ?

16:49 <probono> so is there a command in u-boot or usb otg that would dump the whole nand to file in one go?

21:03 <steev> narmstrong: i know this is a bit weird, but https://gist.github.com/steev/995267e9256cae95c49614aba12cec6f - i get this when i try to use a big endian filesystem/kernel on the odroid eMMC (i haven't tried just an sdcard yet)

21:30 <narmstrong> steev: hi, which kernel version ?

21:30 <steev> 4.18.16

21:31 <steev> I haven’t tried a 4.19 kernel yet as I still have the 4.18 patches around

21:34 <steev> it's very much specific to big endian though, little endian doesn't have an issue with the emmc

21:34 <steev> i'm rsyncing the rootfs across now to test it on an sdcard

21:35 <steev> (this is a rootfs that is tested and working on a nanopi neo plus2 with a 4.14 kernel)

21:50 <xdarklight> chewitt: maybe https://github.com/torvalds/linux/commit/c10bd41ab0b2508a98651ab3e4e9fbc85425eaad is wrong, in that case https://paste.kde.org/pp7xol43k should fix it

21:51 <xdarklight> disclaimer: I'm VERY short on time, it's not even compile tested

21:53 <xdarklight> maybe https://github.com/torvalds/linux/commit/83a6060c0cd07cafdf8baa08e26c602a06977a2c is the root cause if my patch fixes it

23:03 <steev> narmstrong: with just sdcard, instead of spitting out all of the irq bits, it just spits out [ 11.520326] mmc1: error -84 whilst initialising SD card repeatedly

23:37 <steev> i know i'm in territory no one ever goes in, but i'd hope at least it would boot :)

23:49 <steev> narmstrong: is https://github.com/superna9999/linux/tree/linux-4.19-le-amlogic-gx the branch to try for 4.19?
