I have an mt6572 phone that does not utilize normal UART pins and after digging through the source code behind the firmware of the device I noticed this line
# Support share USB DP/DM as UART TX/RX.
MTK_UART_USB_SWITCH=yes
MTK_UMTS_TDD128_MODE=no
So that means it does support UART but in an weird way, right?
The manufacturers had to somehow test the end-user board for bugs in bootloader.
So does anyone know how to set up it and what tools to buy?
