Resolved! USB-UART stability issues over STLINK when "Mass Storage" type enabled on MACOS
I've found that Nucleo-L4R5ZI and Nucleo-L476RG sometimes stop receiving UART data through the STLINK USB interface is Mass Storage type is enabled.I created a program that echos random data sizes (send to board, board echos back). This will crash af...

Resolved! How to conditionally select between pin configurations at compile time?
We have a project where, due to various issues found during development, I've modified the PCB layout and changed a few pin allocations.Is there any way to include multiple configurations from CubeMX and select between these at compile time?This woul...
[STM32F767ZIT6 Rev "Z"] PDR_ON (pin143) internally shorted to VSS (pin130)
Hello,Could someone help me to find the pinouts for STM32F767ZIT6 Rev."Z" please, I've looked everywhere, erratas included. The IC's pinout isn't as per official ST datasheet, and per guidance where the PDR_ON pin should/can be tied to VDD. On this m...
For STM32L072CB, is Revision "1" "P" and Revision "Z" interchangeable?
We received several batches of STM32L072CBT6, among them, there are Revision 1, Revision P, and Revision Z.As per the errata data sheet, these 3 revisions are put in the same column of the chart "Summary of device errata".Does it mean these 3 revisio...
