Yes, your understanding is correct. When enabling Write Reliability (WRREL) on the onboard eMMC of the Apalis iMX8QM, the usable space is significantly reduced. As per the observations, enabling WRREL restricts the usable space to 9.7 GiB out of the total 29.1 GiB capacity. This is due to the alignment and size constraints when configuring the enhanced area for WRREL. Therefore, if you enable WRREL, you will indeed only be able to use 9.7 GiB of your 32 GiB eMMC for user data. This is a limitation that needs to be considered for applications requiring more storage.
