Enable DFU SF on all i.MX6 DHSOM so the SPI NOR can be exposed via DFU, and include dfu_alt_info which exposes the full SPI NOR via DFU. To install new bootloader into the SPI NOR using DFU, it is necessary to pad the u-boot-with-spl.imx to 0x400 Bytes offset first and then send it to the board as follows:
" u-boot=> dfu 0 sf " " host$ dd if=/dev/zero of=pad.bin bs=1024 count=1 host$ cat pad.bin u-boot-with-spl.imx > flash.bin host$ dfu-util -w -a 0 -D flash.bin " Signed-off-by: Marek Vasut <[email protected]> --- Cc: Andreas Geisreiter <[email protected]> Cc: Christoph Niedermaier <[email protected]> Cc: Tom Rini <[email protected]> Cc: [email protected] Cc: [email protected] --- configs/dh_imx6.config | 1 + include/configs/dh_imx6.h | 1 + 2 files changed, 2 insertions(+) diff --git a/configs/dh_imx6.config b/configs/dh_imx6.config index 01db41be2a0..b1eeb8901f4 100644 --- a/configs/dh_imx6.config +++ b/configs/dh_imx6.config @@ -60,6 +60,7 @@ CONFIG_MISC=y CONFIG_PINCTRL_IMX6=y +CONFIG_DFU_SF=y CONFIG_SDP_LOADADDR=0x17ffffc0 CONFIG_SPL_FIT=y CONFIG_SPL_SPI=y diff --git a/include/configs/dh_imx6.h b/include/configs/dh_imx6.h index 09354936d73..d849cb544be 100644 --- a/include/configs/dh_imx6.h +++ b/include/configs/dh_imx6.h @@ -38,6 +38,7 @@ #define CFG_EXTRA_ENV_SETTINGS \ "bootm_size=0x10000000\0" \ "console=ttymxc0,115200\0" \ + "dfu_alt_info=sf 0:0=flash-bin raw 0 0x200000\0" \ "fdt_addr=0x18000000\0" \ "kernel_addr_r=0x10008000\0" \ "fdt_addr_r=0x13000000\0" \ -- 2.51.0
