some comments:0) check and ensure schematics/PCB/component are aligned.1) it is not good to probe at OSC pins, PH0/PH1, as crystal oscillation may be impacted. It is recommended to probe at MCO pin, PA8, by enabling MCO output from source = HSE after...
32768Hz jitter is common and normal, while 32768Hz clock long term stability is good in general.I suppose the "pll lock problem of MAX30001" is not directly link to 32768Hz jitter with STM32U585 or other MCU.
Your question:We would like to have a USB device with MSC only.Can we not activate the UCPD and work with the TCPP01-M12 FLT, DB CC1 and CC2 signals at ground (as on the STM32U545 eval kit)? I think it is OK to have a USB device with MSC to work with...
It seems that no official ARM64 Windows STLink driver is available. Perhaps you may try some workaround found from internet.@AM Could you please help to clarify ?
According to STM32F103C8 reference manual, most of its RTC registers (including time and date) should be kept not changed during power off-on cycle provided that Vbat voltage is available and valid.
