Shame to get hung up on the most basic of steps here but I am struggling to find the solution last few nights
Started off with
$ export MIX_TARGET=rpi0
$ mix deps.get
$ mix firmware
$ mix burn
Which all complete without error but the Pi does not boot up. That lead me to this thread
Where @fhunleth suggested rpi3a
But trying export MIX_TARGET=rpi3a results in same hang with the green LED goes off once then solid green
Then tried the rpi0_2 option also in the same reply
And that fails with a different LED output where it flashes once and then goes DED
I think that is a “card read error” but I do not think it can be that as I did manage to get the Pi to boot with Raspberry Pi OS and on two separate SD cards
So I am not sure if I am still burning wrong MIX_TARGET or missing some simple step or what
I also tried these but they just hung with solid green LED also

Any suggestions would be great
Thanks
