AP6210 Port on Sinlinx SINA33


Recommended Posts

Dear all,

I recently perched a SINA33 from SINLINX after a week of test i download the Armbian source code that is very interesting and started to create an Armbian image for this board.

I created a csc file to start the building.

Spoiler

The csc file code:

 

# A33 quad core 1Gb SoC
BOARD_NAME="Sina33"
BOARDFAMILY="sun8i"
BOOTCONFIG="Sinlinx_SinA33_defconfig"
MODULES="hci_uart gpio_sunxi rfcomm hidp bonding spi_sun7i 8021q a20_tp"
MODULES_NEXT="brcmfmac"
OVERLAY_PREFIX="sun8i-a33"
KERNEL_TARGET="default,next,dev"

 

The compile is done and the image is created. I flash the image with the mainline kernel and worked.

If there is any interesting on this topic i will create another with the more details.

 

Now the problem is that i can't port the AP6210 wifi module that this board came with.

Here is the dts file sun8i-a33-sinlinx-sina33.dts with the wifi modifications

I'm not sure about the clock on dts file      

clocks = <&rtc 1>;
clock-names = "ext_clock";

 

the error that i take

Using a oscilloscope i saw that the clock at SDIO_DATA_CLK of the module is at 50Mhz and that correct.

Any ideas are thought are really appreciated.
