<MoeIcenowy>
but there's also some source to be altered
<KotCzarny>
icenowy: i think he meant dcc send feature of irc
<Xilokar>
Oh, maybe I altered them then ;)
<MoeIcenowy>
KotCzarny: I don't know... Orz
<MoeIcenowy>
sorry :-)
<silviop>
i'm little confused uboot use device three ? or is for kernel ?
<KotCzarny>
no worries, it doesnt work because many firewalls block it anyway ;)
<MoeIcenowy>
silviop: after applying the patch, you should disable "mmc" command in uboot .config, remove the cd pin of mmc0 in config, and set CONFIG_UART0_PORT_F in config
<MoeIcenowy>
silviop: yes it do use dt
<MoeIcenowy>
after some drivers are ported to "Driver Model"
<MoeIcenowy>
most of drivers of aw is not ported to dm now, however, the UART 16550 driver, as a common driver, has been ported
<silviop>
Ok, i will apply the patch and try to recompile
<MoeIcenowy>
you'd also alter .config as what I said
<silviop>
but i have to remove patch for boot from sd i suppose ?
<MoeIcenowy>
yes.
<silviop>
yes about .config i understand
<MoeIcenowy>
you'd better duplicate the u-boot source tree and apply patches on it
<silviop>
Do you know if there is someone with a A33 booting mainline uboot ?
<silviop>
A33 tablet ?
<MoeIcenowy>
me.
<MoeIcenowy>
I have one Q8 and one iNet D978 Rev02
<MoeIcenowy>
both A33
<silviop>
1024*600 ?
<MoeIcenowy>
800x480
<MoeIcenowy>
the iNet D978 Rev02 has 1024x768 screen
<silviop>
1024*768 means 4:3 so its 8 inch ?

4:3 ?
<MoeIcenowy>
yes
<MoeIcenowy>
just look like an iPad 1, except for the Home key
<MoeIcenowy>
the Home key is replaced with a touch key with a LED
<MoeIcenowy>
Onda have a tablet like that one, but the tablet by Onda has 8188eu as wifi, not 8723bs
<silviop>
touch and wifi are ok with mainline kernel ?
<silviop>
nothing happen (only BOOT0 messages on serial brekout)

You may want to activate low level debug (arm->arm-debug)
<silviop>
i need to add base address for 8250 ? (i don't know for A33)
<Xilokar>
0x01c28000
<silviop>
Register offset shit 2 is ok ?
<Xilokar>
(registe offset shift: 2)
<silviop>
ok
<silviop>
no flow control
<silviop>
and 32 bit ?
<Xilokar>
I don't need it
<silviop>
nothing happen
<silviop>
do you tink thata sunxi tool fo ubuntu 16.04 are old ?
<Xilokar>
I don't know, I compiled them from git sources
<silviop>
there is not a --version in tools i will try to compile from git
<silviop>
no difference from git

I suppose that A33 is too new devices with low support and you need to be lucky
<MoeIcenowy>
nope A33 is old enough to get support
<silviop>
i notice that A13 (2013 soc) reach full mainline support in 2016 summer with 4.8 rc kernel (and 2016 uboot)
<Xilokar>
hum...the SPL banner (U-Boot SPL 2016...) should prompt very early
<MoeIcenowy>
Xilokar: if use uSD breakout patch I gave to silviop
<MoeIcenowy>
no SPL banner will show
<MoeIcenowy>
as SPL still uses old uart
<MoeIcenowy>
U-Boot itsels do use uart on bo
<Xilokar>
even with LL_DEBUG ?

Hi
<silviop>
O i would wait some months and will retry with uboot 2017 hoping more robust support to A33 , many thanks
<yann-kaelig>
There is something I don't understand. On the website linux-sunxi.org section Nand or every video or tutorial I found the nand is partitionned with nanda nandb etc... But on my cubieboard2 I don't have these parition, just /dev/nand
<yann-kaelig>
Could you help me to understand that
<mripard>
terra854: yes
<terra854>
About this 5 patches
<mripard>
silviop: the A33 is probably the best supported SoC among the newer ones
<terra854>
which version of the kernel do I patch it with?
<mripard>
current linux-next
<MoeIcenowy>
I think v5 can be patched to master
<MoeIcenowy>
(I mean 4.9.0-rc1+
<apritzel>
MoeIcenowy: I think mripard dropped some of the clock patches from v5, which are not in -rc1
<MoeIcenowy>
ah-oh
<MoeIcenowy>
I still didn't patched them yet
<MoeIcenowy>
as I want to wait them to be merged in :-)
<apritzel>
MoeIcenowy: btw: did you actually see any difference with your MMC calibration code?
<MoeIcenowy>
nope to debug the MMC calibration code I need a DDR SD Card or an eMMC
<apritzel>
I tested it on the latter and it didn't work
<MoeIcenowy>
apritzel: ah-oh
<apritzel>
I think we got the whole calibration thing wrong
<MoeIcenowy>
but I haven't received my M64...
<MoeIcenowy>
apritzel: maybe...
<MoeIcenowy>
as the BSP have nothing about it
<apritzel>
I tried to fix it, but it didn't change anything
<MoeIcenowy>
apritzel: can it work with sun5i-a13-mmc compatible?
<MoeIcenowy>
sun5i-a13-mmc have no DDR capbility
<apritzel>
MoeIcenowy: the BSP writes 0 into the delay registers for anything below HS200
<MoeIcenowy>
BSP is mysterious
jbrown has joined #linux-sunxi
<MoeIcenowy>
if the eMMC can work with sun5i-a13-mmc compatible, I think the problem is DDR.
Leepty has quit [Remote host closed the connection]
<MoeIcenowy>
sun5i-a13 have also only one mod clock, and it do not support DDR for lack of extra clocks
<apritzel>
I think sun5i-a13-mmc worked quite well for me, at least for SD cards
<apritzel>
and U-Boot works fine with the eMMC
<apritzel>
so I suspect that's DDR50 that causing the issue
<apritzel>
;-)
<MoeIcenowy>
apritzel: try mmc with sun5i-a13-mmc
<MoeIcenowy>
not sun7i-a20-mmc (Hans de Goede's patch make it different to sun5i-a13-mmc
<apritzel>
I think U-Boot is not using DDR
<apritzel>
MoeIcenowy: ah, good point
<apritzel>
will check tonight
<MoeIcenowy>
thx!
gianMOD has joined #linux-sunxi
<MoeIcenowy>
the sun5i-a13-mmc before importing Hans's patchset is sun7i-a20-mmc after the patchset
<apritzel>
I was planning to somehow restrict the eMMC to SD mode, seems like using a13-mmc would do exactly that
<MoeIcenowy>
sun5i-a13-mmc is now the least functional compatible -- lack of DDR, lack of New Timings
<MoeIcenowy>
and compatible with all SoCs prior to A13
<MoeIcenowy>
it can be a safe fallback to be written in mainlined dt.
<apritzel>
it's a shame that it was dropped from the compatible list in the DTs then ....
<apritzel>
;-)
<MoeIcenowy>
yes
<apritzel>
maybe I should try a patch then, although mripard was against it already
<MoeIcenowy>
we cannot say sun50i-a64-mmc is compatible to sun7i-a20-mmc (as sun7i-a20-mmc needs 3 clocks input), but we can say sun50i-a64-mmc is fully compatible to sun5i-a13-mmc, with the latter as a fallback
<apritzel>
MoeIcenowy: I am more concerned about the new sun7i dt no longer being bootable with older kernels
<MoeIcenowy>
apritzel: yes
<MoeIcenowy>
but it's by design
<MoeIcenowy>
you cannot also boot a sunxi-ng enabled H3 dt on an older kernel
<MoeIcenowy>
I think now I should resend my A64/H3 OTG-OHCI PHY driver...
