Repeated write SD RAM + reset

[Lmali.1]

Hello,

I'm working on STM32WB55.

Is there any limitation to write to (internal) SD RAM and do a system reset?

I want to build an application that requires a lot of writing to SD RAM and then do system reset (and read the SD RAM and act according the data).

Thanks,

Lior

​No there is no limitation on write access to the SDRAM before a reset.

Just be aware that not all the SRAM aera is accessible for the user. SRAM1 is accessible witout any limitation but SRAM2 (2a and 2b) have some protected areas defined by the option bytes SBRSA for SRAM2a and SNBRSA for SRAM2b.

Thank you, this is what I thought but wanted to be sure

Thanks!
