Eugh :/
<megal0maniac_afk>
Makes sense, there's no ID pin so I don't see any other way of doing it
<megal0maniac_afk>
Weirdly, it has a 4 port hub. Instead of having the 4 ports on the hub connected to the physical ports, they only connected 3 and branched off the DP DM pair that go to the hub into the 4th physical port
<megal0maniac_afk>
So if you were to switch to OTG, all the other USB ports will break

dds an image file to /dev/nand2
<mnemoc>
megal0maniac_afk: basically mru suggested you to use the major/minor of the nodes to see if /dev/nanda and /dev/nand1 are equal
<megal0maniac_afk>
mnemoc: I have no idea what I'm comparing against
<mru>
ls -l /dev/nanda /dev/nand1
<mnemoc>
megal0maniac_afk: but it's basically just a CONFIG_ diff. the compatibility mode will make the current sunxi-nand driver to allwinner's nand%c schema instead of the standard %d
<mru>
compare the numbers
<megal0maniac_afk>
/dev/nanda doesn't exist
<megal0maniac_afk>
That's why I'm asking
<mru>
can something that doesn't exist be the same as something that does?
<megal0maniac_afk>
If it exists elsewhere, then yes
<mru>
so ls -l it elsewhere
<megal0maniac_afk>
I don't have elsewhere
<mnemoc>
he is preobably trying to follow a tutorial that uses the nand%c notation
<megal0maniac_afk>
mnemoc: Well yeah, my question is whether or not nand1 and nand2 are equivalent to nanda and nandb
<mru>
then I suggest understanding what that step in the tutorial is actually trying to accomplish
<megal0maniac_afk>
mru: None, yet
<mnemoc>
megal0maniac_afk: short answer is "yes"
<mnemoc>
megal0maniac_afk: nandb is the equivalent of nand2 on legacy kernels or sunxi-3.4 kernels with the compatibility CONFIG_ enabled
<mru>
there could also by a performance monitoring unit for peripherals
<mru>
it's pretty clear that the a7 perf monitors are on irq 152/153
<ssvb>
mru: apparently mripard got a reply telling him about SW_INT_IRQNO_PMU (which is already present in the header files)
<megal0maniac_afk>
libv: Pardon my ignorance. We all have to start somewhere
<mru>
ssvb: yes, and that's one of two mentions of "PMU" in the "manual"
<mripard>
ssvb: power management unit is a completely different interrupt handled by a chained interrupt controller
<mru>
the other being a memory region
<mru>
so whatever it is, it isn't the in-cpu perf monitor
<libv>
megal0maniac_afk: no, it's fine, just busy tightening up the page

The firmwares are all over the place. They use pcduino and cubieboard2 firmware images. Cross-compatibility between devices is nice, but it also makes amess
<megal0maniac_afk>
*makes a mess
<libv>
yeah
<libv>
it will reduce the chance of us ever having a direct iteaduino_plus_a20 target
<libv>
for uboot
<megal0maniac_afk>
Well technically the cubieboard2 target should suffice for cubieboard2, ibox, pcduino and iteaduino_plus_a20
<mnemoc>
ssvb: unless there are no interesting issues
