Hello @ADani,Very good to have the issue narrowed to SDRAM Read, for the errata I suggest to see if you have the specific conditions for entry 2.3.5 and 2.3.15 for example the RBURST bit, doing Burst instruction to the FMC (LDM = Load Multiple instr...
Hello @Dany,I suggest to look at AN4861, Table 20 "Example of graphic implantations with STM32 in different hardware configurations", for 400x600 I think at least you need LQFP144 package and with LQFP100 you should aim for low end display configura...
Hello CYesi.1Here the sequence used in CubeMX repo example:/* The Following Wakeup sequence is highly recommended prior to each Standby mode entry
mainly when using more than one wakeup source this is to not miss any wakeup event.
- Disable ...
In the CubeMX Repository there is examples/projects (running on STM32H7B3i-DK) and code template you can start with.For the known limitations of the device, check the Errata.Regards,Hajji.
Try to output the RTC_OUT on the PC13, visualize it with a oscilloscope and look for deviation from the 1MHz, also RTC_out on the PC13 should still be functional with standby mode so that can give an idea on what's happening when entering, during and...
