Manual Test - Verify eMMC is enumerated in mass storage mode - (WoW64 for Arm64)
This is a manual test & it should be run outside HLK by following the manual instructions provided below. If this test is run as an automated test from HLK studio/controller, the test will pass by default without testing any functionality. --------------------------------------------------------------------------------------------------------- Manual instructions to run this test: 1. Make sure the device is powered off and all the DIP switches on the debug board are in the OFF position. Note that you do not need a debug board to put the device in MSM. 2. If you're using KDSERIAL, disconnect the serial cable or close WinDbg as it interferes with mass storage hotkeys. 3. Position the phone on the debug board and plug in power but do not press the power key on the device or the debug board. 4. Plug in the micro-USB cable into the USB2 portion of the USB3 port. This acts as a wake event for the device. 5. Press and hold the Vol+ and the Camera buttons down during UEFI boot. This should bring up UEFI BDS menu. 6. The device should reboot into mass storage mode and a new physical disk would appear in the disk manager (diskmgmt.msc). NOTE: Common mistake: Device would neither auto power on nor enter mass storage mode if the micro-USB cable is inserted into USB2 port. --------------------------------------------------------------------------------------------------------- Note: This test is associated with an optional feature: System.Client.MobileHardware.
