*Miscellaneous tests that include GetBitSlice, unloading of sdbus.dll, and SDIO bus ioctl

*Memory list

*Feature fullness

Setting Up the Test

The Windows Embedded Compact platform under test must have an SD card (v1.1) inserted and mounted.

The OS design must also include at minimum:

* SYSGEN_SDBUS=1

* SYSGEN_SD_MEMORY=1

Note:When you are building a new image you need to set the image flag IMGSDBUS2 equal to 1 in order to use the new bus (sdbus2.dll). When IMGSDBUS2 is set to 1, sdbus2.dll is picked up during the makeimg process and is renamed to sdbus.dll in the generated image.

Running the Test

The following table shows the command line parameter for the SD Bus Level Functional Test.

Command line parameter

Description

/device <card>

Specifies the Secure Digital card type to test.

/manual

The user must manually insert an SD card to continue, the reason is the host may not be designed to be unloaded and reloadable. If that is the case, client need to manually insert/eject an SD peripheral in order to load the test driver for testing purposes.

/softblock

Soft-Block operations increase performance for large I/O operations on cards that support small block sizes in hardware by reducing the number of driver stack traversals. Soft-Block operations only benefit SDIO cards as multi-block operations are mandatory for all memory cards.

Follow these steps to run this test:

1. Insert the SD memory card into the device's SD slot.

2. Run the test, modifying the command line if necessary.

Verifying the Test

When the test completes running, verify that "PASS" appears in the test log for all sub-tests.

Troubleshooting the Test

* Ensure that the OS design includes the SD card sysgen(s) necessary to support SD card.

* If the tests are failing, check to make sure from the Tux test log that the replacement of the default SD card driver to the test SD card driver happened successfully. If the driver was not replaced properly, the test may behave unexpectedly.

* You may need to specify the "manual" flag in the command option if the SD host controller on the Windows Embedded Compact device is not designed to be unloadable and reloadable.
