When there is LCD error code like T_*** and L_**** series, it is mostly the issue of LCD hardware issue.
the error code can be mixed because of several issues happen together.

define LCD_ERROR_SD2828_0 0x01
define LCD_ ERROR _SD2828_1 0x02
define LCD_ ERROR _FPGA_CONF 0x04
define LCD_ ERROR _MIPI_DSI_ERROR 0x08
define LCD_ ERROR _MIPI_DISPLAY_OFF 0x10
define LCD_ ERROR _FPGA_VERSION_LOW 0x20
define LCD_ ERROR _MIPI_NO_SCREEN 0x40
define LCD_ ERROR _MIPI_AUO_L055 0x80

Troubleshooting:

1. Confirm your workflow when error reported, do you replace a new screen?
2. Check if all the wires relate to LCD and the board connect well
3. Check if the screen model is right, and a wrong FPGA firmware can also be blame. (the different screen may request different adaptors,
please check the manufacture if you are going to use a different LCD screen, also chitu website has a list about which screen has been supported)
4. Try to connect another LCD if you have on hand, to check if the new screen is DOA(Dead on arrival)
