BaremetalPi 0.1.1 doesn't seem to work with Julia 1.7.0

[GregMc]

Sorry to advise

But I think BaremetalPi 0.1.1 doesn't seem to work with Julia 1.7.0

I have an older Julia version 1.6.1 and BaremetalPi works fine on that ...

This is the Error :-

Hi @GregMc

Thanks for the bug report. I am already aware of this bug. The problem is that I was not able yet to compile v1.7 to the Raspberry Pi zero (which is the only one I own) so that I can fix the problem :(

I think I have a solution. I will do this in a separate branch.

Thanks Ronan ,

I'll test it when you get a chance to propose a solution.

Hi Ronisbr ,

Julia-1.7.1 has just been released - so I checked - and unfortunately BaremetalPi still exhibits the error.

I am using RasPi4 ( with 8 Meg of memory if I remember correctly )
