Hi,I have a question regarding the backup SRAM in the STM32U5. The reference manual is not clear about this:On the one had, it mentions the following Which seems to indicate that it is possible to place the device in standby without powering SRAM2. H...

Hi,I making a product that has the STM32U5 running from a battery, most of the time being in one of the low power modes. I can use the debugger to .. debug my code, step through it, use SWO etc, and this all works great. However, as long as the debug...

Hi,I am working with what I think is the latest STM cubeMX:But, I am hitting an issue contantly that during debugging, on certain "lines of code" the debugger hits some unexpected condition, and then decides to exit, automatically stopping the debugg...

(And by the way, for anyone reading this for the first time, perhaps this helps to more quickly absorb the info): - flash line: amount of bytes to be e.g. written/read in one go (halfword,double word, ..)- the flash line "not being writable" => Bits ...

I might be off here, but I'd like to understand the impact of this. I was considering using x-cube-eeprom, but then found this topic. If I am correct: - This library defaults to writing 64 0-bits every boot to guarantee data integrity. => If the devi...

Thank you aime, that's very clear now

And note from the datasheet:It really seems possible that only the BKSUPSRAM is enabled and not the 8kB or more in the SRAM2.But, this would mean:- The comment in the RM is confusing- The PWR_ModesSelection example is confusing Anyway, I'd like to he...

Some extra information: When connecting once through STM32CubeProgrammer, the power usage does not drop, also after disconnecting. This was the main issue I logged.With STM32CubeIDE however:- when flashing a new binary through STM32CubeIDE through th...
