Peripherial view does not show 8bit addressBlocks

When trying to add AVR peripherial view support to PIO debugger by providing SVD files converted from Atmel’s atdf. PIO seems to not show anything in the peripherial view if the adressBlock is less then 4 bytes.

Consider this SVD

Nothing gets shown in the view, but the register appears if addressBlock.size is set to 4 or more.

I’d be happy to debug, but although according to Community PIO Plus is supposed to be open source, I can not find the source of platformio-vscode-debug. Where is it published?

PS In case of a missing addressBlock, PIO fails with an extremely unhelpful “Cannot read property ‘0’ of undefined”

At https://github.com/Rahix/atdf2svd/issues/25#issuecomment-858741454 I’ve posted a reference with 8-bit regsiters which works nicely per https://github.com/platformio/platform-ststm8/pull/38, see screenshots.

+1 on this. I thought I opened an issue about that long ago but I can’t find it anymore. I’ll open a separate issue for that.
