Resolved! OTP area in flash is not empty on brand new STM32WB5MMG
Good day,On a brand new SMT32WB5MMG MCU, I have found that the One-Time Programmable area is not empty. See the image. The OTP area starts at 0x1FFF7000. There is also some data right before the OTP area - what is that doing there as well?For context...
Why can ST-Link debugger reconnect after STOP2 but not SHUTDOWN mode?
I am using STM32WB55, and try to implement power saving functionality.I am using FreeRTOS and have a task that checks for the sleep conditions, and if they are met, it shall put the device in the lowest power mode possible. Wake-up is then triggered ...

Hi, from the micropython repository there is a note on a problem regarding address resolution, it is reported at this link.Are there any details about it? is this a known and solved problem? or still open?Thanks and regards
Resolved! load capacitance of recommended quartz for HSE lower than minimal load capacitor trimming
The quartz used for HSE on the nulceo-wl55jc and on the reference design for stm32wl is NX2016SA 32MHz EXS00A-CS06465, which has a 10pF load capacitance (the BOM for reference design even mentions 8pF, but the quartz reference is actually 10pF).The m...
