ADC/linker problem - won't compile (STM32L432KC)

[nebelgrau77]

I'm trying to use the ADC example with an STM32L432KC. If I specify version 0.6.0 of the crate, it can't find ADC1, ADC_COMMON or rcc.ccipr. I used git = "git = "https://github.com/stm32-rs/stm32l4xx-hal" instead and it seemed to compile OK, but then it won't:

note: "rust-lld" "-flavor" "gnu" "--eh-frame-hdr" "-L" (omitted)
= note: rust-lld: error: undefined symbol: ADC1_2
>>> referenced by stm32l4.arnfbrxu-cgu.3
>>> stm32l4-3c82b24cdd335e86.stm32l4.arnfbrxu-cgu.3.rcgu.o:(__INTERRUPTS) in archive

I believe I have everything necessary installed, I actually have some firmware already working on the same board, I just wanted to add ADC. Is it something I'm doing wrong, or an actual issue with the crate?

Thanks!

Seems like an error in the PAC with the fields and interrupt definition.
Could you have a look between the PAC and the reference manual?

I don't think I'm versed enough in those details, but I see that in PAC there are the following lines:

ADC1:  
    _modify:    
        _interrupts:      
            ADC1:        
                name: ADC1_2

and ADC1_2 also appears in the NVIC vector table in the RM as ADC1 and ADC2 global interrupt (page 322).
I don't know if it's any help to understand the problem, though.

Hmm, unclear what is the issue here.
But the error you get are consistent with an error in the PAC.

Could you open an issue in stm32-rs/stm32-rs and link it here?

OK, done: stm32-rs/stm32-rs#561
