[tech-lists]

Hi,

(in my reply below I'm using md5 to differentiate btwn files with
identical names)

I didn't even think about the u-boot already on the image! I just
followed the notes i made in
https://cloud.zyxst.net/~john/FreeBSD/current/rpi4b/installing.txt
which installed u-boot.bin dated Oct 5 and has md5 of
d208763206d50d3ec40b04cc81685b29 and that worked.

The one provided with
FreeBSD-14.0-CURRENT-arm64-aarch64-RPI-20210311-15565e0a217-257277.img
has md5 967c3a667af11512bafd2525ef97af5f and is dated 11th March. I've
not tried this one, as I overwrote it before booting it for the first
time. 

I got the latest u-boot.bin when Klaus kindly offered it (md5
1b868cc0550df026e1a4e7baf2cca223 dated 13th March)

My reference was:
https://github.com/raspberrypi/firmware/raw/master/boot/fixup4.dat
https://github.com/raspberrypi/firmware/raw/master/boot/start4.elf

from my notes but yeah, point taken. I am still trying to get my head 
around git, after using svn and cvs for years.

I'd not installed the port at any stage. The md5 for the start4.elf 
above is 1a13569ce69f758c87a71dba78750f0d and the md5 of the one I downloaded
is 741c0a91981196e2bc01b0b25f458045 (dated 10th March).

OK. So in my example, in this case start4.elf (of 10th March), the absolute URL would be 
https://github.com/raspberrypi/firmware/raw/0591568b29a724de406aa737fc8e13f68c423f3f/boot/start4.elf
?

...and that's a stable URL? just making sure

thanks,
