Hi All, i use ikgt-uefi-loader as below steps, it hang, what mistakes i made ？ 1、I download iKGT 1.2.1 source package from "https://01.org/zh/intel-kgt/downloads" and ikgt-uefi-loader from " https://github.com/01org/ikgt-uefi-loader";. 2、Use ikgt-uefi-loader instead of loader in iKGT 1.2.1 package 3、build ikgt_pkg.bin by “ make debug=1” 4、build preload_x64.efi by “build.sh” 5、copy ikgt_pkg.bin + preload_x64.efi to usb disk 6、run preload_x64.efi in efi shell, but Exception : read file into buffer succeed! file size = 729089 Image Load Addr = 3FF4D000 Image Size = 729089 find the the specified headers ikgt_header->magic = 0x6D6D76656967616D ikgt_header->size = 52 ikgt_header->entry32_offset = 0xFFFFFFFF ikgt_header->entry64_offset = 0x34 ikgt_header->rt_mem_size = 0x1520000 ikgt_header->ldr_mem_size = 0x20EE000 ConvertPages: failed to find range 20EE00010000000 - 20EE000120EDFFF allocating loadtime mem at the fixed address failed, try to allocate it at any address below 1GConvertPages: failed to find range 152000012C00000 - 15200001411FFFF allocating runtime mem at the fixed address failed, try to allocate it at any address below 1G allocation of ldr/rt memory for ikgt succeed! load-time memory addr = 0xAD902000 run-time memory addr = 0xAEE22000 platform_info->memmap_addr = 0xAD900018 platform_info->memmap_size = 0x1A70 call ikgt loader entry_addr = 0xAEE22034 loading ikgt... !!!!
