First rule of spaceflight: you never schedule a launch on Fri 13 or April Fools Day.

I'll just assume it's going to be a scrub and block time to watch the following day.

Hey ADI - I fixed your embedded code:

descriptor = &oa_tc6_buffer_struct; //no_os_calloc(1, sizeof(*descriptor));

1) Avoid dynamic memory allocation for embedded apps

2) dynamic allocation unnecessary for a single object that will live the entire life of the program

Ok, I know I found some older .8mm packages last year for tests, and I can't find them right now.

I loaded up ST Cube MX, selected 90-178 pin pkg that are 0.8mm BGA and sorted by price. Mouser has STM32H523ZCJ6 (BGA144) for $4.12 @ qty 10 - in stock. 250MHz, 272k RAM.

So, I wonder when Iran is going to test a nuke device. We know they have plenty of enriched material, and 60% is good enough for an inefficient device.

And, when they do test it, do they do it in a remote area or on a military target? Like a US aircraft carrier or base,

I would have to think that there are US special forces on the ground right now looking for this material. That's gotta be a central goal of any major conflict.

So it looks like the IEEE standard for single pair Ethernet 100Base-T1L is still in play, it has just exited the working group phase.

The spec is 500 meters at 100Mbps over a single shielded twisted pair, and allows for downshifting to 10Base-1TL up to 2000 meters. This is distinct from the T1S short range versions that go to a 20-40 meters for cars.

Looking at the docs which were updated this week, I'm guessing the standard gets approved this year. Contributors from Analog Devices are heavily involved, and they might have the first PHYs out.

This slide deck talking about the pros/cons between PAM3/4/5 is pretty cool. They picked PAM3.
