Hello.
It seems that your device uses non-standard good block ratio that is not
supported by sunxi nand driver. Does it work on sdk lichee kernel?

Hello
Can you post dmesg output after inserting module?
It seems that it erase whole nand flash when somethink wrong.
Of cause it must be fixed before trying to merge it to kernel tree.

Meminfo works strange on lichee kernel: on first boot zq is 0x7f, but after
standby it is 0x12b73b7f
I added this fucntion to meminfo utility to get full dram register dump on
a20:
static int
sun4i_dram_regs_print(void)
{
void *base;
base = mmap(NULL, SUN4I_IO_DRAM_SIZE, PROT_READ

sunxi-3.4 nand format is incompatible with lichee-3.4 (sdk kernel).
You can try this port of new nand driver:

Try https://github.com/reinforce/gt9xx . It is WIP now, but you can try to
debug it.

Hi Punith,
Try run
fbset -xres 720 -yres 480 -x -a
before starting Xorg, it works for me with LCD+HDMI configuretion.
Why didn't you try 480p HDMI mode?

Dmitry

Hi Punith.
I have not tested hdmi and dual-screen on android, i only tested scaler and
it worked. Also i tried to change framebuffer size by fbset. I used

Try separate screen configuration, it is more stable. try last version of
a10disp. It has instruction to enable dual screen after boot. Disable scaler
before readfbinfo command.
If you only need vdpau support, try to fix OSD mode in patch,

Hello. It is possible to change framebuffer size using fbset. Use fbset -a

Set 480p mode on hdmi to make same resolution and use scaler of you HDMI

It seems that DRAM controller uses too much power.
While i was trying to fix mystically broken dram self-refresh mode in sunxi
kernel on my tablet, i wrote this patch:

It allows to skip entering self-refresh mode and disabling Pll5 and avoids

Bluetooth adapter seems to be disabled by default.
In stock gpl-violating kernel it controls by /sys/class/usb_wifi/rtl_wifi/bt

I think it is impissible to run decoder and encoder at the same time because it
uses same memory regions.
But you can try to write converter you need. Decoder and encoder uses same
libraries. Try look at the sample codes and encode each frame after encoding.
Other way is decoding some count of fr
There is softfloat. It can work on armhf, bus static linking is impossible, but
you can link it to shared object and load dinamicly like libhybris (simply use
libhybris with android version.
As alternative you can use PoC opensource encoder, that can encode only I
frames. It has very hing bitrat

I have Wexler.tab 7200 with broken standby mode in sunxi kernel (in aw
kernel suspend works).
I have tried to debug standby code using RTC to trace it (i have no access
to UART now), it hangs after this lines in dram.c:
reg_val = mctl_read_w(SDR_DCR);
reg_val &= ~(0x1fU<<27);
reg_val |= 0x12U<<27
I tried to use kexec to boot kernel.
Kexec from sdk/stock kernel works only with sdk kernels, kexec from linux-sunxi
kernel works only with sunxi.
sdk' kernel is unuseful because g2d API is broken, usb sometimes crashes (NPD
somewhere in usb code).
