Looks like it built successfully this time. I'll let you know how I get along with the systemd issue, I may not have time until next week.
In the meantime, you should be able to use the released filesystem and replace just the kernel... Jonathan Cormier

Hi Sandeep,
I've run into some issues building the systemd package during the build. I am looking into it. Jonathan Cormier

1. Great
2. I'm not sure what would have caused this file to get truncated. Seems like some kind of file corruption, not sure. Can you try to rebuild just qtbase? @MACHINE=mitysom-am57x bitbake qtbase -c cleanall && MACHINE=mitysom-... Jonathan Cormier

Hi Sandeep, the crops/poky group decided they needed a newer python, etc in their 18.04 ubuntu image which breaks the older thud build. We can work around this by mounting an empty t... Jonathan Cormier

Hi Kim,
I am relieved you got your system loaded.
Have a nice weekend.
With regards,
Mike Michael Williamson

Hi again,
We managed to fix our loading problem.
The bug was due to our FPGA binary, not the loader itself.

Hi Rune,
The VDD_CORE voltage is set in the device tree and thus configured when the kernel loads.
To switch to 0.75V operation, regulator-min-microvolt and regulator-max-microvolt should be set to 750000. Jonathan Cormier

Short question: Does the SOM_62 and SOM_62A support 0.75V core operation? If yes, how is this selected.

Great, note that at least for this boot. The ethernet phy came up as address 3 so it would have worked with the original kernel as well. Jonathan Cormier
