It is the protocol used in NXP's +i.MX SoCs ROM Serial Downloader and provides means to download a program +image to the chip over USB and UART serial connection. + +The implementation in U-Boot uses the USB Downloader Gadget (g_dnl) to +provide a SDP implementation over USB. This allows to download program +images to the target in SPL/U-Boot using the same protocol/tooling the +SoC's recovery mechanism is using. + +The SDP protocol over USB is a USB HID class protocol. USB HID class +protocols allow to access a USB device without OS specific drivers. The +U-Boot implementation has primarly been tested using the open source +imx_loader utility (https://github.com/toradex/imx_loader). + +The host side utilities are typically capable to interpret the i.MX +specific image header (see doc/README.imximage). There are extensions +for imx_loader's imx_usb utility which allow to interpret the U-Boot +specific legacy image format (see mkimage(1)). Also the U-Boot side +support beside the i.MX specific header the U-Boot legacy header. + +Usage +----- + +This implementation can be started in U-Boot using the sdp command +(CONFIG_CMD_USB_SDP) or in SPL if Serial Downloader boot mode has been +detected (CONFIG_SPL_USB_SDP_SUPPORT). + +A typical use case is downloading full U-Boot after SPL has been +downloaded through the boot ROM's Serial Downloader.
