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.
