My first reaction is that passthrough should be a pointer to EFI_SCSI_IO_PROTOCOL, not an instance of that structure.
But you're crashing because This is uninitialized and you dereference it. Maybe you want the gImageHandle you can get from a standard library? -Jaben From: parmeshwr_pra...@dell.com [mailto:parmeshwr_pra...@dell.com] Sent: Wednesday, September 25, 2013 6:15 AM To: edk2-devel@lists.sourceforge.net Subject: [edk2] error in uefi application Dell - Internal Use - Confidential Hi All, I have developed below code, it is crashing the system, can anybody tell me why ? what is solution ?
