Error generating psoc6_pac

[dioguerra]

Hey,

I'm trying to configure and fiddle with Rust for the psoc6 CPU and I seem to have hit some sort of problem. I downloaded the original psoc6_pac from this git repo: https://github.com/psoc-rs/psoc6-pac and can generate the modules without problems straight from the repo cargo build --release --features "rt"

although, if I do regenerate modules files by instantiating the generate.sh script it seems that I am hitting a redefinition error

cargo build --release --features "rt"
   Compiling psoc6-pac v0.0.1 (/tmp/psoc6-pac)

Some errors have detailed explanations: E0072, E0428.

Edit: No It does not fix it... Not exactly sure what the fix here is and which package is causing this (svg2rust or form), but it seems that removing the redefinition and setting the

FM_CTL: crate::Reg<fm_ctl::FM_CTL_SPEC>

on line 3 seems to fix the error.

It appears to me that the redefinition on line 76 appears to be for documentation purposes only? Pointers would be nice.

I also tried with a different svd file (from the module I intend to use) and it seems that the same error occurs (although no relevant diffs are shown between the 2 files): https://www.google.com/search?channel=fs&client=ubuntu-sn&q=github+VSCode_OnethinxPack_Linux%2F

I tried different versions of form and svd2rust and it seems that error persists, so not exactly sure what is going on,,,

It is just speculation. But I think it is because cluster and register it contains have identical names. https://github.com/psoc-rs/psoc6-pac/blob/4332a41692514ec9140d1b5de69ee3c60691b43e/svd/psoc63.svd#L5971-L5975 Fast fix is to rename one of them. Other workaround is to use different identifier formats for registers and clusters. See #805 and #794

I have a newer PAC here, which might give you fewer issues? https://github.com/ferrous-systems/psoc-experiments

Actually I managed to go thru your stuff, quite usefull for my examples, didnt try your PAC. I think the problem might come from the SVD file itself. Something that the original author (or you) might have fixed after generating the src code i suppose?

Still, dosen't really take into account automated full build of every dependency if manual changes need to be made...

I'll check it out tho. Thank you @thejpster
