[U-Boot] Questions on lthor usage

[S Durga Prasad Paladugu]

Hi,

I have a query on lthor usage.

How do i specify the altsetting while sending the lthor download from host.
In dfu we are specifying that with -a < altnum/altname>. I have alt setting
to copy the linux images(uImage.devicetree and ramdisk) to DDR at
prescribed locations in my device side. Also if i am downloading these
files what option should i use at host side(this is not tar.gz and pitfile).

Regards,
DP

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.
