Introduction to ARM3:15
RISC1:02
ARM Architecture6:25
Microarchitecture4:40
Processor Family6:26
Different Architecture Implementation5:14
This lecture explains how the same architecture can be implemented differently by microarchitecture, with varying pipelines, caches, and MMUs, exemplified by arm7tdmi-s, arm920t, and cortex a53 and cortex a72.
Cortex A53 vs Cortex A721:07
ARM Profiles2:59
How ARM Makes money2:19
System on Chip2:23
SoC Block Diagram3:55
SoC vendors license Arm cores and integrate memory controllers, usb, spi, i2c, uart, gpio, gpu, and other peripherals to form a chip like am335x on Beaglebone.
SIngle Board Computer3:47
Examples of SBC2:27
ARM Documentation3:00
ARM Quiz

How to check for ARM Linux Support1:42
Assess linux kernel support for the arm core (cortex-a7/a9), verify SoC compatibility from the vendor, and confirm device drivers for peripherals like gpu, camera, display, usb, uart, and spi.
Boot folder in Linux Kernel9:04
Kernel folder in Linux Kernel10:48
Explore the Linux kernel folder structure for embedded boards, including arch/ subfolders, common and configs, and examine irq handling, vector tables, entry.S, setup.c, and time init.
Other Folders in Linux Kernel arm directory10:51
cpuinfo file7:13

SCSI Rootfs7:58
Enabling required kernel configs1:56
Enabling BLK_DEV_SD kernel config5:20
Enable BLK_DEV_SD kernel config and verify block devices and rootfs on versatile boards, then correct dtb and board selection to boot kernel to rootfs.
Setting up roots similar to vexpress-a9 rootfs6:40
Copy the rootfs to the sd card on the versatile pcb, mount partitions with a loop device, and adjust fstab, banner, and init scripts to mirror the vexpress-a9 setup.

Introduction to Raspberry Pi32:46
Downloading Raspbian OS7:37
Download the Raspberry Pi Raspbian OS from the official site, choose the lite image for CLI use, and mount the image to extract the kernel and rootfs.
Building QEMU From source6:00
Adding rootfs support4:12
Add rootfs support to the virtual embedded Linux board by resizing the SD card to four GB and configuring root on the MMC partition for a Raspberry Pi Lite image.
Enabling USB Keyboard and USB Mouse3:04
Creating password for pi user5:05
Enabling SSH7:00
Building Linux Kernel for Raspberry Pi7:04
Enabling UART for Raspberry PI8:01
