Is your environment setup in a way that DFU is working properly and
data is stored in the RAM?

First of all, lthor accepts *.tar or *.tar.gz files. Therefore you need
to tar the uImage file anyway.

Secondly, on the target only the file name sent from host matters (like
uImage or u-boot-mmc), since it is used to find proper entry in
dfu_alt_info environment variable.

I'm also curious if the downloading data to RAM will work with lthor.
The main use case of lthor was to store data in an eMMC device.
