Hi Supreeth, The intention of the patch is to fix the LUN display issue in the iSCSI device path text. In the UEFI spec, the according definition is clarified as " The LUN is an 8 byte array that is displayed in hexadecimal format with byte 0 first (i.e., on the left) and byte 7 last (i.e, on the right), and is required. "
The current test has the mistake and need make sure the display order is correct. The input is required to check the TEXT to binary system format, vice versa. It is the reason for the magic string "iSCSI(MyTargetName,0x12AB,0x0000005678000000,CRC32C,None,CHAP_BI,TCP)" And the text format defined in the UEFI spec is: iSCSI(TargetName, PortalGroup, LUN, HeaderDigest, DataDigest, Authentication, Protocol) I will generate the new patch to do definition at first and then do initialization. Thank you for this comment.
