Hi, Could you please guide me how to implement test items in "Physical Test Specification for Host Version 3.00"? Take 1.3-1 for example to implement. 1.3 TG1.3: Mandatory Test Items for Speed Class (SDSC/SDHC) 1.3-1 Memory Management – AU and RU: Divide user area into multiple AUs and divide AU into multiple RUs. (in chapter 4.13.1 of SD spec) I will appreciate it if you could help me.
