While I try to find the root cause why my USART DMA setup is not working i have detected that the STM32Cube F1 version provided with framework-stm32cube in version 1.1.0 is quite old (actually V1.0.4 from 29-April-2016). The current version would be V1.0.6.
The Problem I have is that ST does not provide older STM32 Cube versions to get the Documentation and the example code for V1.0.4 (Shame on you ST btw. … that’s so annoying, can’t find words for that without being rude!).
Beside of that the LL driver support has been massively extended in V1.0.6 … or in pio not all the LL drivers are provided … cant check this as I cant find the original V1.0.4 package from ST.
Is there a good reason to stay with V1.0.4 in pio?
If not … Is it possible to estimate when a update will be provided within pio?
Last nut not least … I think that the root cause for my DMA problem is somehow related to the Cube version as the V1.0.6 examples have the same problem as my own code … no TX output.
