Boot modes

At startup, the boot source used by the internal BootROM is selected by the BOOT pin and

OTP bytes.

Initial boot mode

Comments

UART and USB(1)

Wait incoming connection on:

– USART2/3/6 and UART4/5/7/8 on default pins

– USB high-speed device(2)

Serial NOR Flash(3)

Serial NOR Flash on QUADSPI(4)

e•MMC(3)

e•MMC on SDMMC2 (default)(4)(5)

NAND Flash(3)

SLC NAND Flash on FMC

Reserved (NoBoot)

Used to get debug access without boot from Flash memory

SD card(3)

SD card on SDMMC1 (default)(4)(5)

UART and USB(1)(3)

Wait incoming connection on:

– USART2/3/6 and UART4/5/7/8 on default pins

– USB high-speed device on OTG_HS_DP/DM pins(2)

Serial NAND Flash(3)

Serial NAND Flash on QUADSPI(4)

1. can be disabled by OTP settings.

2. USB requires 24 MHz HSE clock/crystal if OTP is not programmed for different frequency.

3. Boot source can be changed by OTP settings (e.g. initial boot on SD card, then e•MMC with OTP settings).

4. Default pins can be altered by OTP.

5. Alternatively, another SDMMC1 or SDMMC2 interface than this default can be selected by OTP.
