From 3d9433e70c26d1b4e849522a3aa40be44c7a9ac1 Mon Sep 17 00:00:00 2001 From: Sam Protsenko Date: Wed, 26 Feb 2020 19:43:01 +0200 Subject: [PATCH] configs: am335x_evm: Enable DFU over TFTP support DFU over TFTP flashing method might be helpful in order to speed-up the flashing process of big images (as DFU works over USB EP0, which is quite slow). Also, it's a good backup option in the case when USB got broken (either in software or hardware), to avoid resorting to SD card boot. This config option was present in am335x_boneblack_defconfig, but we have to use generic am335x_evm_defconfig now, as BBB defconfig was removed in commit 8fa7f65dd02c ("configs: Remove am335x_boneblack_defconfig"). So this patch merely brings that option back. Tested on BeagleBone Black: => setenv dfu_alt_info $dfu_alt_info_emmc => setenv ipaddr 192.168.0.100 => setenv serverip 192.168.0.1 => setenv updatefile update_uboot.itb => dfu tftp mmc 1 Where 'update_uboot.its' file looks like this: /dts-v1/; / { description = "Automatic U-Boot update"; #address-cells = <1>; images { u-boot.img.raw-1 { description = "U-Boot binary"; data = /incbin/("u-boot.img"); compression = "none"; type = "firmware"; load = <0x60000>; hash-1 { algo = "sha1"; }; }; }; }; And 'update_uboot.itb' is generated as follows: $ mkimage -f update_uboot.its update_uboot.itb Newly flashed U-Boot works fine.
