It should work on any RPi with USB device controller available on the micro-usb/c-usb connector. AFAIK, besides RPi4, only some RPi0 has USB device mode available. Other RPi's have USB hub connected to DWC2 controller, so switching DWC2 to device mode is not enough to make it working. However I have access only to RPi3 and RPi4. >> CONFIG_DM_VIDEO=y >> CONFIG_SYS_WHITE_ON_BLACK=y >> CONFIG_CONSOLE_SCROLL_LINES=10 >> diff --git a/include/configs/rpi.h b/include/configs/rpi.h >> index 77d2d5458a1..f502915ad53 100644 >> --- a/include/configs/rpi.h >> +++ b/include/configs/rpi.h >> @@ -70,9 +70,18 @@ >> #define CONFIG_TFTP_TSIZE >> #endif >> >> +/* DFU over USB/UDC */ >> +#ifdef CONFIG_CMD_DFU >> +#define CONFIG_SYS_DFU_DATA_BUF_SIZE SZ_1M >> +#define CONFIG_SYS_DFU_MAX_FILE_SIZE SZ_2M >> +#define ENV_DFU_SETTINGS \ >> + "dfu_alt_info=u-boot.bin fat 0 1;uboot.env fat 0 1;zImage fat 0 1" >> +#endif >> + >> /* Console configuration */ >> #define CONFIG_SYS_CBSIZE 1024 >> >> + > New line sneaked in. > > Regards, > Matthias > >> /* Environment */ >> #define CONFIG_ENV_SIZE SZ_16K >> #define CONFIG_SYS_LOAD_ADDR 0x1000000 >> @@ -185,6 +194,7 @@ >> #define CONFIG_EXTRA_ENV_SETTINGS \ >> "dhcpuboot=usb start; dhcp u-boot.uimg; bootm\0" \ >> ENV_DEVICE_SETTINGS \ >> + ENV_DFU_SETTINGS \ >> ENV_MEM_LAYOUT_SETTINGS \ >> BOOTENV >> >> > Best regards -- Marek Szyprowski, PhD Samsung R&D Institute Poland _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
