3.4.1 UART Boot Mode

UART boot is one of the peripheral boot modes supported on TDA4VM. It is very useful when primary boot media like SD interface is not available.

ROM supports booting from MCU_UART0 via X-Modem protocol. The entire UART-based boot process up to U-Boot (proper) prompt goes through different stages and uses different UART peripherals as follows:

WHO Loading WHAT Hardware Module Protocol
Boot ROM tiboot3.bin (R5 SPL) MCU_UART0 X-Modem
R5 SPL sysfw.itb MCU_UART0 Y-Modem
R5 SPL tispl.bin (A72 SPL) MAIN_UART0 Y-Modem
A72 SPL u-boot.img MAIN_UART0 Y-Modem

For the detailed process for using UART boot mode, see the faq-tda4vm-detailed-step-for-uart-boot.
