Hi all,


working on a Linux driver for this module,


on CMD 18 (and other), from the upper layer, i am getting a value of 0x1200 (4608) for block size (BLKSZE field).

As a bit-width, this value can be applied, but wondering if it is legal, and what it can cause, since datasheet shows a maximum of 4096.
