PC Data Center Mobile: Lenovo Mobile: Motorola Smart Service Parts COMMUNITY My Account A more specific question would be, is there a known bootable memory format that the BIOS/UEFI can recognize after the daughter card is enumerated? Googling has not yielded much success for me and these standards, and how the bios or UEFI conform to said standards during boot appear to be tribal knowledge and hard to discover. Description. See the UEFI 2. From UART log, there is a lot of empty lines in Jetson UEFI firmware. If the EFI memory map has additional entries not in the E820 map, you can include those entries in the kernels Solution. The following system BIOS/uEFI level (s) are affected: All levels. The bit depth can either “rgb” or “bgr” to match specifically those pixel formats, or a number for a mode with matching bits per pixel. It sets up some basic EFI functions with efi_init(), sets up U-Boot global_data, allocates memory for U-Boot’s malloc(), etc. Functions and structures¶ Here is the (but not in UEFI spec) • What can it do? –Insert low-overhead measurement start/stop hooks in driver • (low, but not zero overhead. 3 Use UEFI Memory Allocation Services , DEBUG_WARN, and DEBUG_INIT all enabled.
