* 我看到omega2的文档，好像现在支持直接在设备上gcc了，嗯，这有点帅，
omega2+的内存是128MB，omega2则是64MB，能跑得动gcc也是神奇
（很容易内存不足挂掉），我想arm9是不是也能试试。。。

## VoCore2, MT7628, The Coin-sized Linux Computer
* https://vocore.io/v2.html
* Directly write to memory/register
```
Directly write to memory/register
We made a simple tool for this, download here, its name is "mem", put the executable file into /bin/ in VoCore2.
1. read from register/memory, for example: 0x10000060, pin control register
example: mem 0x10000060
2. write to register/memory, must in 32bits(4bytes)
example: mem 0x10000064 0x05540555
here is an example bash script flash the LED every second on VoCore2
mem 0x10000064 0x05540555;
mem 0x10000604 0x1000;
while [ 1 ];
do mem 0x10000634 0x1000;
sleep 1;
mem 0x10000644 0x1000;
sleep 1;
done
```

```
我搞明白怎么用vocore2运行LVGL例子和驱动usb屏幕，
之前失败其实是因为fbusb.ko的驱动程序不兼容（因为需要和内核版本完全一样才能正确运行），
所以要么重新编译内核或者重新编译驱动程序。
然后我想起其实可以通过wifi来刷固件，然后找了一下，发现有个touch固件自带fbusb驱动和LVGL，
刷完就可以看到LVGL例子（开机启动，不需要insmod）。具体效果略，
因为触摸比较卡顿，可能和屏幕速度或者mt7628主频低有关，也许作者不想明说
```
```
1. use PC wireless connect to your VoCore hotspot, open browser view 192.168.1.1 or 192.168.61.1 (I use 61.1).
2. LuCI console using username: root, password: vocore,
3. select "System" -> "Backup/Flash Firmware"
4. uncheck 'keep settting', and "Flash Image". choose 20200628.touch.bin
5. after flashing, will auto start running /root/demo, it's a LVGL demo program
