Hello,
Which Marvell SoC is used on this platform? The script I added recently covert only the new Armada SoCs like A8K and A8K+. It will not work with A3K family.

This is the fourth version of patches for adding support for the Turris Omnia board, a router developed by the CZ.NIC.
I'm still facing trouble testing turris_omnia on latest v2018.01.
First, that made me notice there's no README for how to test and deploy. I'm aware of temporary: sendbeacon /dev/ttyUSBx
I have to admit, that don't know anything about this "sendbeacon" tool.
https://gitlab.labs.nic.cz/turris/misc/tree/master/sendbeacon
./tools/kwboot -t -B 115200 /dev/ttyUSBx -b u-boot-spl.kwb -p
This is what I have used, when I tested / debugged images for Armada XP / 38x. Please note that the init sequence is somewhat "fragile" - so I added the -q and -s parameters, to optionally finetune the startup timings:
# kwboot ... -q <req-delay>: use specific request-delay -s <resp-timeo>: use specific response-timeout
You might what to play a bit with these parameters as well.
I saw them but had no idea what to pass as values. ;) I did try -a, but it worked with and without.
BTW: I don't have access to the Omnia router, so I can't test anything on this specific platform.
BTW2: Kosta from Marvell just recently added a new tool / script, to help debug / boot Marvell MVEBU boards:
tools/mrvl_uart.sh
He told me that its better to use than the "old" kwboot tool. I never found the time to use it up until now, so I have no personal experience. But I'm pretty sure that Kosta did a great job here. So please give it a try.
I did not get it to work ... or was not patient enough.
It seems, just as with kwboot, the tool alone is not enough. If I use sendbeacon before and in mrvl_uart.sh just press enter without another reset, then the transfer does work for me, and if in the script I add -b $default_baudrate to the minicom line, then I also see useful output.
But it does not affect the reported non-SPL boot breakage, i.e. it still reboots from SPI immediately after loading from UART.
Regards, Andreas
