Hello,

Does SRAM on TM4C129x series have any check functions?
For example, parity, ECC and so on, I'm expecting.

Best Regards.

Hi,

There is no mention of check functions for SRAM at the device datasheet.

Hi,

@Yusuke,

While there is no test in the user manual, it was an TI application note for safety tests - it was removed from the list since it is a little bit old, but I re-posted here, for documentation: (and has a sram test code inside, just need to be adapted a little for the size of 129 micro).

Hello Nomoto,

The SRAM on any of the TM4C devices do not have ECC or paroty check or any check function in hardware. As Petrei mentioned, an old application note to do the same in software is the only solution
