RT1176 FlexRAM ECC enabled by default?

[Mike_Z]

Is the RT1176 FlexRAM ECC enabled by default, or does the user need to intentionally enable it with a set of preload configuration commands? We're using the MiMXRT1170 - EVKB.

We observed this line of code, but unsure what exactly this means. Thanks in advance for any assistance.

Please refer to MIMXRT1170RM chapter 38.7.1.16 OCRAM Pipeline And ECC Enable (PIPE_ECC_EN)

I suggest you can refer to SDK demo "evkbmimxrt1170_mecc_single_error_cm7"
