Small mobile phone based on the [LCSC Taishanpai Development Board]

The entire production process was based on learning from the Taishanpai Training Camp documentation and Bilibili videos. I haven't added my own ideas yet.

Initially, the screen didn't light up at all. Then, after reading the tutorial, I learned that the resistors in red don't need to be soldered. The PWM backlight pull-up/pull-down circuit can be done by default. For FB feedback, you only need to attach one resistor. If you attach two 10Ω resistors, the final current will be 40mA, which exceeds the screen backlight requirements, causing it to overheat.
Removing the unattached resistors still didn't solve the problem. Then, in the discussion group, I saw the reminders from the experts: the diodes should not be reversed. The Schottky diodes marked in green have a direction; they are used in the BOOST boost circuit.
There is a vertical line drawn on one end of the DSK34 silkscreen; aligning it with the vertical line on the board means the direction is correct.
After resolving the above issues, the screen still couldn't display properly, only the backlight was on.
I initially suspected it might be due to an incorrect firmware flashing method, so I used the [scrcpy](https://lceda001.feishu.cn/wiki/K7mpwTvm0izeiYkOrIWcxrnzngR) screen mirroring tool to show that
the firmware had been successfully flashed. It was probably a problem with the MIPI interface soldering
. I also tested the touch screen, and it worked fine.
