Here's my new write-up of ten Linux-capable chips you really ought to know about, plus some background on how to get started in embedded Linux development: jaycarlson.net/embedded-linux/

All source code of abandoned software should be open sourced. Manufacturers should be forced to do so on the end of service date.

Recorded and uploaded my presentation at ELCE2020.
CU at the virtual event?

@geert Barely, and only if you bought it for that purpose.

My A4000's battery-backed RTC seems to be sitting too close to a black hole:
-rtc-rp5c01 rtc-rp5c01: setting system clock to 2020-06-05T13:44:41 UTC (1591364681)
+rtc-rp5c01 rtc-rp5c01: setting system clock to 2020-06-09T01:54:20 UTC (1591667660)
The previous boot (v5.7) was indeed on June 5.
Last boot (v5.9) was today, though.

linuxfoundation.org/blog/2020/ says that commit 2f3fbfdaf77f ("Merge tag 'arm-dt-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc")
is what took the kernel to over 1,000,000 commits.

Since I sent that pull request, I object to the following step of picking the specific winner as one that is not in this branch.

Instead, how about this one:

git log --oneline 2f3fbfdaf77f^2 | head -n 533 | tail -n 1

Online conferences are fun. Even if you're not registered for attending, people send you invites for specific interesting sessions.

Liechtenstein is the single safe European country to travel to. Time to go shopping for some Hilti gear?

DTS has: "mentor,num-eps = <16>;".
Combined with "ctrlrequest->wIndex & 0x0f" in the mUSB driver, any endpoints beyond 15 are silently truncated?

I spoke too soon: while everything is detected fine, two USB-serial adapters just don't work, but no errors are logged.
Removing the camera fixes one USB-serial adapter. Getting rid of the second hub fixes the other adapter. I guess I'm running into limitations of the BeagleBone Black USB controller?
Back to one fully-populated 10-port USB hub...

Shuffling the USB cabling in my board farm, taking into account hub topology inside the 10-port hubs, as some newly added USB devices fail to work.
Things seem to work now, except for the webcam that keeps an eye on a board's display, which logs "bandwidth not wide enough".

I gave it a try for mine, defended in 1999:
- 3 working links,
- 1 link is automatically redirected to a generic page on the site,
- 22 broken links (404 or domain not found).

Google is (must be) your friend...
