There are two methods of compiling Uboot: method1 and method2.If you refer to the /README file, it mentions “If this variable is defined, U-Boot will embed a device tree binary in its image.” Please keep in mind that this is suitable for debugging and development only and is not recommended for production. stress is a workload generator tool designed to subject your system to a configurable measure of CPU, memory, I/O and disk stress. With Windows-like CPU metric, when load is at 100 you do not really know whether it is optimal use of CPU resources or system is overloaded. The load average is a number corresponding to the average number of. Load average, usual to NIX systems, can be more than 100 (per CPU/core) because it actually measures number of processes ready to be run by scheduler. The Linux top command is one of the stalwarts of Unix-like operating systems. You can press shortcut keys to change how information is displayed on the top dashboard. Top displays critical information about your systems, like CPU and RAM utilization, details about running processes, and more. Before we compile the Uboot, please add the following flag “CONFIG_OF_EMBED=y” in the am43xx_evm_defconfig file. Linux CPU Load Stress Test with Stress-ng Tool In this guide, we shall look at two important tools, stress and stress-ng for stress testing under your Linux systems. The first CPU-related information is present on the very first line: the load average. Run 'top' in the Linux terminal to launch this utility.Change directories to the Uboot source code and open the defconfig file associated with your board: “/board-support/u-boot-xxx+yyyy/configs/am43xx_evm_defconfig” CPU load Linux exports various bits of information via /proc/stat and /proc/uptime that userland tools, such as top (1), use to calculate the average time system spent in a particular state, for example: iostat Linux 2.6.18.3-exp (linmac) avg-cpu: user nice system iowait steal idle 10.01 0.00 2.92 5.44 0.00 81.63.Open another console terminal and navigate to the latest PSDK that was installed First because processes often fluctuate - it's not unusual to see process that is completely occupying the cpu occasionally flicker to 0 in top, and if you have multiple intensive processes running they can alternate, taking turns to use 100 while the other uses 0, making it hard to read.
