Raspberry Pi 4

Easier said than done
Now when I boot up (takes ages to get to login!)
there is no IP on ETH

I give up, will download the img file again and try that approach.
RPi works with Hakan's SD card but I want to start from scratch to learn how to setup this RPi4 and 7i96 with LCNC + PlasmaC

Where is this file to be found linuxcnc-pi4.img.zip

Wanted to download again and see if it works, but I can not find it!

Tried once more with that img = will not boot!

try this one. i just pulled it off my sd card

drive.google.com/open?id=1JbPiXr_i8be1GWVPG8PJmr7NlOo6WpKD

Downloading now, will try later this evening. THANKS!

Sorry, but my 16Gb SD card is not big enough for that image.

I'll see if i can go on and shrink the filesystem

OK

Which brings up a problem we are going to have forever as SSD'd take over the spinning rust job.

The question to be answered, is can e2fsresize fix it going both ways? I know it can expand a crushed image that has had its end of disk inode table moved to a position just after the last data, thereby making the zip a few kilobytes bigger than the actually used data, but no one has explained to me, how, and with what utility this was accomplished with.

The bottom line is that you by x amount of memory, and its random from card to card, often varying by over a gigabyte for a so-called 64GB u-sd card, so the next card is NOT identical due to the use of substitute sectors being used for bad sectors found during test. But ext2-3-4 expect that backup inode table to be at a fixed end of disk location as recorded in the first sectors. But its not the same offset as the one before it, or the one behind it. The question then is how can we "fix" one of these zips, so it can be written back to any u-sd big enough to hold the actual data. Seems to me it ought to be possible tp shrink an image by half a gig oe such in that event.

If there was a memo, I surely missed it.

Ideas?

Thanks
