On a SD, where it is easy, backup good uboots before changing
bs=1M count=16 of=suitable_name,,, since it is same device, no need to mess with mbr
It is not sure if or maybe not some uboot remnant on emmc, this may or may not interfere
(from failed installs)
Because there is a battery, it can remember a "bad state", you may have to do "long presses"
Easiest to reburn image on SD, as your dd command line
If it then boots, then try to install
The long press dance........
If not, hard pwr-off(8s), try start (don't just tap, hold 1-2s, try twice (or 3) times)
If not, hard reset (20+s), try start
if not, try hard pwr-off again
I actually have had to this above dance, somewhat annoying
So far, the only recent distro that I have personally tried that actually boots every time is Kali. I don't think kali runs very well, but so far, it always boots.
Manjaro is a crapshoot. After it fails to locate my EMMC 4 times, it launches an emergency shell.
Sometimes it finds my EMMC first try, sometimes 4th. If it misses the 4th attempt, manjaro will never boot, but the boot logo will keep spinning lol.
How can I build a uboot that keeps listening for the EMMC, rather than giving up after 4 tries? Does a noob guide exist to do this? I have some experience in C++ and Python.
I have seen the output often enough to know that it can fail more than once and still end up booting. Maybe on the 14th check it will connect and boot. However the limit is 4.
I tried flashing the uboot from kali onto manjaro, but that didn't work, it seems quite a bit different. Also, when booting from kali, the LED exhibits significantly different behavior.
