Well I do not know if it's already written in some post,
But I found a way to record an image on the Emmc without the adapter or the serial cable
1.- Download any minimal image for SD and record it in SD (tested with debian 0.78 minimal)
2.- You start the Rock64 with the SD card put the eMMc in place and the jumper so you do not activate it
3.- Once the minimum image has been removed, remove the jumper
4.- cd / usr / local / sbin
5.- sudo rock64_reset_emmc.sh
6.- sudo nano sd2emmc.sh
7.- curl -L https://github.com/ayufan-rock64/linux-b...m64.img.xz | unxz -c> / dev / mmcblk0
8.- You can put the image you want after download another example
curl -L https://github.com/ayufan-rock64/linux-b...m64.img.xz | unxz -c> / dev / mmcblk0
another way from a personal pc
curl -L -u Domain \ user: passwd smb: //192.168.1.9/download/xenialokrock64.img.xz | unxz -c> / dev / mmcblk0
9.- CTRL +O enter CTRL +X
10.- sudo chmod 0754 sd2emmc.sh
11.- sudo ./sd2emmc.sh
12.- When the prompt returns to write,
sudo shutdown -h now,
13.- When this rock64 is turned off, you take the SD out of its site and reboot again without SD
14.- The image will start from the eMMC and you will have your image recorded in the SD
I hope it helps you all and if you see any error or problem you tell me

| How to customize DSI RGB format |

Hi
I would like to change the DSI format to RGB565.
Therefore, fix the following setting values from DTS.
[sun50i-a64-pine64-plus.dts]
Code: 2182 lcd_dsi_if = <0x2>;
2183 lcd_dsi_lane = <0x4>;
2184 lcd_dsi_format = <0x3>;
2185 lcd_dsi_eotp = <0x0>;
2186 lcd_dsi_vc = <0x0>;
2187 lcd_dsi_te = <0x0>;
But, the RGB format of DSI was not changed.
I confirmed with the fbset command.
Code: pine64@pine64:~$ fbset -i
mode "1024x600-80"
# D: 55.002 MHz, H: 97.178 kHz, V: 79.981 Hz
geometry 1024 600 1024 1200 32
timings 18181 16 -478 4 610 4 1
rgba 8/16,8/8,8/0,8/24
endmode
Frame buffer device information:
Name :
Address : 0x57354000
Size : 4915200
Type : PACKED PIXELS
Visual : TRUECOLOR
XPanStep : 1
YPanStep : 1
YWrapStep : 0
LineLength : 4096
Accelerator : No
pine64@pine64:~$
Is there a mistake in how to change the DSI RGB format?
Also, I tryed change to RGB format with reference to the following page.
http://linux-sunxi.org/Fex_Guide#FEX_Description
[sun50i-a64-pine64-plus.dts]
Code: 2136 disp@01000000 {
2137 compatible = "allwinner,sun50i-disp";
2138 reg = <0x0 0x1000000 0x0 0x300000 0x0 0x1c0c000 0x0 0x7fc 0x0 0x1c0d000 0x0 0x7fc 0x0 0x1ca0000 0x0 0x10fc>;
2139 interrupts = <0x0 0x56 0x104 0x0 0x57 0x104 0x0 0x59 0x104>;
2140 clocks = <0x6a 0x6b 0x6c 0x6d 0x6e>;
2141 status = "okay";
2142 device_type = "disp";
2143 disp_init_enable = <0x1>;
2144 disp_mode = <0x0>;
2145 screen0_output_type = <0x3>;
2146 screen0_output_mode = <0x5>;
2147 screen1_output_type = <0x1>;
2148 screen1_output_mode = <0x5>;
2149 fb0_format = <0x5>;
2150 fb0_width = <0x0>;
2151 fb0_height = <0x0>;
2152 fb1_format = <0x0>;
2153 fb1_width = <0x0>;
2154 fb1_height = <0x0>;
2155 };
But, the result did not change.

Hostname: rockpro64
CPU Frequency:
Core0: 1416Mhz
Core1: 1416Mhz
Core2: 1416Mhz
Core3: 1416Mhz
Core4: 1800Mhz
Core5: 1800Mhz
CPU Governor: performance
Temperature: 40 C
I am wondering how I can push 4 LITTLE cores to 1.5Ghz and 2 big cores to 2.0Ghz.
For Banana PI M3, there is a file called sys_config.fex, has content like:
B_LV3_freq = 1608000000
B_LV3_volt = 920
B_LV4_freq = 1200000000
B_LV4_volt = 840
B_LV5_freq = 0
B_LV5_volt = 840
B_LV6_freq = 0
B_LV6_volt = 840
B_LV7_freq = 0
B_LV7_volt = 840
B_LV8_freq = 0
B_LV8_volt = 840
[vf_table1]
I am thinking if there is similar file in rockpro64, so I can tune it by myself to unlock 2.0Ghz/1.5Ghz
BTW - I have a good power supply 12V/6A, full height heat sink, and a good cooling fan running on top of the sink. want to unlock the potential of RK3399 CPU
