Support an U-Boot script included in uimage instead of flashlayout file (text file in tsv format). This feature is used to execute this script directly when U-Boot is loaded in DDR (for update without STM32CubeProgrammer for example). A simple example with dfu-util only is: $> echo "dfu 0" > script.cmd $> mkimage -C none -A arm -T script -d script.cmd script.uimg $> mkimage -T stm32image -a 0xC0000000 -e 0xC0000000 -d script.uimg \ script.stm32 $> dfu-util -d 0483:df11 -a 1 -D tf-a.stm32 $> dfu-util -d 0483:df11 -a 0 -D script.stm32 $> dfu-util -d 0483:df11 -a 0 -D u-boot.stm32 $> dfu-util -d 0483:df11 -a 0 -e Then you can used dfu-utils to update your device To increase speed, you can also switch to fastboot protocol with: echo "fastboot 0" > script.cmd Signed-off-by: Patrick Delaunay <patrick.delaunay at st.com> --- .../arm/mach-stm32mp/cmd_stm32prog/cmd_stm32prog.c | 14 ++++++++++++++ 1 file changed, 14 insertions(+)
