Bare metal, Assembly language • Re: BCS mnemonic (?)

Try RRXS instead of RRX. I think RRX used like that doesn't set the carry flag.

I could be wrong. I'm a bit rusty on assembler.

You're not wrong. The {S} suffix is required to shift bit 0 into the carry flag.
For ARMv7, (32-bit) the reference is in section 7.7.118 of the Architecture Reference Manual. Having the Architecture Reference handy is invaluable for assembly programming.
