Resolved! High current draw in STOP mode when RTC Alarm has been used

We have a very weird behavior in a battery powered IoT device. We should have a very low STOP mode current draw of 1.4 uA @ 3 VCC. The problem is, as soon as we use the RTC Alarm just once and although the alarm already fired during NORMAL operation,...

Resolved! STM32H7 max SDRAM clock speed for 480MHz

ST example uses 400MHz / 4 = 100MHz for SDRAM. What should the SDRAM clock be when the system is running at 480MHz? If we use 480/4 then it is 120Mhz for SDRAM, but datasheet shows max of 100MHz for SDRAM! Are we stuck running SDRAM at 60Mhz? Or run ...
