I went to Randor[^] but it said it was unable to load the requested member's information.
I ask because I know he's a Microsoftie and I'm having a gnarly issue with a driver.
His posts seemed to indicate that he knew a great deal, so I thought I'd try summoning him in my post in the Hardware forum. 
Is there anyone else who could help with a driver signing issue?

I get "This account has been closed" - Member Profile - Randor (273597). He came close to closing it in the past a couple times because he doesn't like conflict.

That's weird, because I'd say that this place is one of the friendlier online hangouts.

On a related note, am also missing the wise words of @BillWoodruff for a few days now. Any news about him?
|
|
|
|
|
I've also been wondering if he's OK.
|
|

He is old enough to expect bad news, in case we would ever get them.

We're linked on LinkedIn so I can message him.

Are you offering to do so?

AFAIK, he closed his account due to some situations he didn't like.
You are right, CP is one of the most friendly sites I know, but it still has its own problems, its own trolls and its own dynamics...
Some people are more sensitive to some exernal impulses than others or their principles are more rigid than others.
I can't tell what was exactly what made him leave CP, I miss him too, he is / was a really good professional.

What does Linux pukes mean ( horrible expression ) ?

Puke is a pejorative for a low level soldier, kinda like a Grunt.
I’ve given up trying to be calm. However, I am open to feeling slightly less agitated.
I’m begging you for the benefit of everyone, don’t be STUPID.

Horrible word though, thanks for the explanation

I did it. I got the STM32MP157-DK evaluation board running on bare metal, no operating system. Boot time is pretty fast, but could be faster if I move away from using U-Boot, which thinks my code is a linux kernel. 
I think I managed to get SPI code in place too but I have yet to wire up a logic analyzer to test with.
This is crazy. It also required me to install linux on my laptop. The VMs just hated me.
I even got both cores working, and I have a codebase that has my graphics library integrated, which by the way, I made a design decision a year ago with it that saved my bacon on this project. The library isn't fundamentally thread-safe BUT you can isolate different screens, and each handles its own rendering, so you can run them on different cores without synchronization between them.
Trouble is I still need synchronization anyway, and I may have to make some spinlocks and such with std::atomic if that works or LDREX and STREX asm instructions if it doesn't. Lovely.
Everything I'm doing I haven't done since maybe the 1980s. Messing with boot loader code, writing OS level system interaction, etc, and that was 8 and 16 bit processors which were far simpler than even this little embedded monsters.
It's an adventure

When something like that happens to me the cry of 'It's alive, alive I tell you, they said I was mad but it's alive, alive I tell you' comes from my desk.

Congrats! That is so cool.
It requires a 3A power supply?
