Hi,

How can a noclear SRAM be implemented meaning SRAM content persistency over Reset in AURIX TC2xx/TC3xx?

Thank you.

Hi Bernie,

SRAMs are initialized in AURIX devices on startup by the Firmware. If the Firmware should not initialize the data the UCB_DFlash value for HF_PROCONRAM needs to be changed.

Fields RAMIN and RAMINSEL.

Please be careful if you touch UCBs, a mistake can lock the device.

Best regards
Lucas
