Sorry for resurrecting such an old thread. I am trying to accomplish the same here: boot imx8mm-evk via SDP. I tried building Schremp's U-Boot from https://git.kontron-electronics.de/linux/u-boot/-/commits/v2020.01-ktn with the additional changes: --- a/configs/imx8mm_evk_defconfig +++ b/configs/imx8mm_evk_defconfig @@ -85,3 +85,14 @@ CONFIG_MXC_UART=y CONFIG_SYSRESET=y CONFIG_SYSRESET_PSCI=y CONFIG_DM_THERMAL=y +CONFIG_SPL_USB_HOST_SUPPORT=y +CONFIG_SPL_USB_GADGET=y +CONFIG_SPL_USB_SDP_SUPPORT=y +CONFIG_SPL_WATCHDOG_SUPPORT=y +CONFIG_USB=y +CONFIG_USB_EHCI_HCD=y +CONFIG_USB_GADGET=y +CONFIG_USB_GADGET_MANUFACTURER="FSL" +CONFIG_USB_GADGET_VENDOR_NUM=0x0525 +CONFIG_USB_GADGET_PRODUCT_NUM=0xa4a5 +CONFIG_CI_UDC=y diff --git a/include/configs/imx8mm_evk.h b/include/configs/imx8mm_evk.h index 991fe0056c4a..d41704d60754 100644 --- a/include/configs/imx8mm_evk.h +++ b/include/configs/imx8mm_evk.h @@ -35,6 +35,11 @@ #endif +#define CONFIG_EHCI_HCD_INIT_AFTER_RESET +#define CONFIG_MXC_USB_PORTSC (PORT_PTS_UTMI | PORT_PTS_PTW) +#define CONFIG_MXC_USB_FLAGS 0 +#define CONFIG_USB_MAX_CONTROLLER_COUNT 2 + /* Initial environment variables */ #define CONFIG_EXTRA_ENV_SETTINGS \ "script=boot.scr\0" \ but I get the following error: U-Boot SPL 2020.01-01059-geb5a1eb17cea-dirty (Jul 01 2021 - 19:45:58 -0300) Normal Boot WDT: Not found!

This version of U-Boot does not generate u-boot.itb by default, so I passed the following line in mx8mm_usb_sdp_spl.conf: .../u-boot/flash.bin:dcd,clear_dcd,plug,jump header Any help is appreciated. I plan to upstream this support once I get it resolved. Thanks, Fabio Estevam
