From d0686c69ff6cb8d8e63052bde8ca00e6468dd88d Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Wed, 18 Mar 2020 09:25:02 +0100 Subject: [PATCH] stm32mp: stm32prog: support for script 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 Reviewed-by: Patrice Chotard --- .../arm/mach-stm32mp/cmd_stm32prog/cmd_stm32prog.c | 14 ++++++++++++++ 1 file changed, 14 insertions(+) diff --git a/arch/arm/mach-stm32mp/cmd_stm32prog/cmd_stm32prog.c b/arch/arm/mach-stm32mp/cmd_stm32prog/cmd_stm32prog.c index 15bbdc2cb6..baf9b6bd1e 100644 --- a/arch/arm/mach-stm32mp/cmd_stm32prog/cmd_stm32prog.c +++ b/arch/arm/mach-stm32mp/cmd_stm32prog/cmd_stm32prog.c @@ -6,6 +6,7 @@ #include #include #include +#include #include #include "stm32prog.h" @@ -44,6 +45,7 @@ static int do_stm32prog(cmd_tbl_t *cmdtp, int flag, int argc, int dev, ret; enum stm32prog_link_t link = LINK_UNDEFINED; bool reset = false; + struct image_header_s header; struct stm32prog_data *data; if (argc < 3 || argc > 5) @@ -71,6 +73,18 @@ static int do_stm32prog(cmd_tbl_t *cmdtp, int flag, int argc, if (argc > 4) size = simple_strtoul(argv[4], NULL, 16); + /* check STM32IMAGE presence */ + if (size == 0 && + !stm32prog_header_check((struct raw_header_s *)addr, &header)) { + size = header.image_length + BL_HEADER_SIZE; + + /* uImage detected in STM32IMAGE, execute the script */ + if (IMAGE_FORMAT_LEGACY == + genimg_get_format((void *)(addr + BL_HEADER_SIZE))) + return image_source_script(addr + BL_HEADER_SIZE, + "script@1"); + } + enable_vidconsole(); data = (struct stm32prog_data *)malloc(sizeof(*data)); -- 2.39.5
