[PATCH 2/4] stm32mp: stm32prog: Add CONFIG_CMD_STM32PROG_SERIAL and _USB

Patrick Delaunay patrick.delaunay at foss.st.com
Thu Feb 25 13:37:01 CET 2021


Add CONFIG_CMD_STM32PROG_SERIAL and CONFIG_CMD_STM32PROG_USB to
independently select the support of UART or USB communication for
STM32CubeProgrammer.

For serial boot over UART, user can deactivate CONFIG_CMD_STM32PROG_SERIAL
to use U-Boot console of binary loaded by UART (for board bring-up for
example).
