tuxd3v, sounds to me like you're most likely confused about something

where u-boot is, and where it is loaded to, are separate addresses, maybe you've mixed these?

it it uses the first 8K

finally I found that the issue is that -- the RTC time went to 22th century

(maybe because of the timer bug

smaeul: I'm working on decompiler for or1k
<
megi>
I'm pretty far, just need to finte tune the calling convention
<
megi>
It's written in sleigh
<
smaeul>
megi: in what framework? standalone? ghidra?
<
smaeul>
ah, exciting! I wanted to do that at some point! thanks!
<
megi>
It works surprisingly well
<
megi>
I'll put it on github soonish
<
megi>
it even handles the delay slots correctly
<
megi>
Ghidra is kind of an amazing piece of SW, all I did was write a sleigh file and a buch of xmls
<
smaeul>
megi: still, that's amazing! thank you so much
<
smaeul>
btw which firmware are you looking at?
<
smaeul>
ah, so you started with symbols?
<
megi>
it has some dwarf info, which helps
<
megi>
I also added a register map I have collected during my previous reveng efforts
<
smaeul>
register map?
<
megi>
a simple file containing names of registers and addresses on A83T soc
<
megi>
it can be loaded into ghidra directly
<
smaeul>
oh, you mean MMIO
<
megi>
which is why you see the UART0_* names in the screenshots
<
smaeul>
that blob has debug printfs left in it, so it's the easiest one to reverse :)
<
megi>
nice, I have something similar for H3 arisc
<
MoeIcenowy>
smaeul: I backported the mainline one with some of its early version
<
MoeIcenowy>
and I even don't know when the thing happened -- the time changed is RTC time
<
smaeul>
hmm, weird
<
megi>
I'll probably take a break from it for another week, I've already spent too much time on it

hello! I'm looking for assistance trying to boot 4.19.28 on a NTC C.H.I.P computer (based on Allwinner R8 SoC)
<
lavamind>
the kernel boots up but is unable to find the rootfs
<
mru>
does it give a reason?
<
lavamind>
mur: I think the key is "UBI error: cannot open mtd 4, error -19"
<
mru>
there's no mention of mtd in the log
<
mru>
did you enable the driver?
<
lavamind>
mru: yes CONFIG_MTD_NAND=y and CONFIG_MTD_NAND_SUNXI=y present in /boot/config-4.19.28
<
mru>
is the devicetree correct?
<
lavamind>
mru: that's beyond my current ability to tell :(
<
lavamind>
I've tried both with the devicetree that's built and the one from the working 4.3.0-ntc kernel
<
lavamind>
it's using this devicetree /usr/lib/linux-image-4.19.28-lib3/sun5i-r8-chip.dtb in /boot
<
lavamind>
how can I chceck whether its correct ?
<
lavamind>
looking at the kernel log differences, in 4.3.0-ntc I see "vcc-3v3: supplied by ipsout" while in 4.19 there's "vcc3v0: disabling"
freemangordon has quit [Ping timeout: 258 seconds]
<
lavamind>
mru: I've found out how to decompile .dtb files, and compared them
<
lavamind>
there are many differences but one that stands out is that the 4.3.0-ntc (working) has a NAND subsection describing partitions
<
lavamind>
eg. rootfs@1000000 {
<
lavamind>
I'm wondering if that might be the problem
<
lavamind>
the -lib3 is the one generated using 4.19.28

lavamind: you trying to resurrect the CHIP ? :)
<

vagrantc: lol no, but I finally have a use for it and I want to run a recent kernel on it :P
<
lavamind>
I just want to resurrect
*my* CHIP heh
<
vagrantc>
if you manage to get the MLC stuff working, i'd be curious ... i've got a pocketCHIP as well as an early generation CHIP
<
vagrantc>
haven't really messed with them lately
<
lavamind>
vagrantc: well you can patch out the error and apparently it works for a bit until the filesystem gets currpted heh
<
lavamind>
but since there's been work to have it play nicely with MLC I'm wondering maybe I can help a bit by just testing it
<
lavamind>
vagrantc: if your CHIP is a 4GB model with SLC NAND you won't have the problem though
<
lavamind>
AIUI not all CHIPs were fitted with the 8GB MLC chip
<
vagrantc>
i seem to recall one was upstreamed, and it wasn't the one i had
<
lavamind>
vagrantc: hi, by the way :)
<

you still need to pick up your water bottle, its still at my house :D
