The onlyl time it appears to be dead(no leds) is when I disable eMMC and insert an sd, thats when its dead. Would this pressing trick work if I have the eMMC disabled and just try with the sd??
Say you have a perfectly fine booting install on emmc
And then you make a mistake, put in something (SD card) for say a A64 (I have done this)
Opps,, it's dead......even with no SD card in, dead, dead, dead (no leds)
Well, you can (just a guess) take off back, press reset ,, OR
press power, at least 20 seconds,,(then regular 1s press to turn on),, IT'S ALIVE (in frankenstein voice)
FWIW (and BTW, I experiment, have had to do this perhaps 15 times by now)
Please note, bad uboot MUST be removed or disabled
Thanks for all the suggestions!

You shouldn't be able to do that unwittingly, I don't think. But I'm not real familiar with these other linuces. Do keep trying as wdt suggests.Thanks for your help though! I'll keep trying. As you say, I don't think I did anything to the SPI.
