About BL2 startup process:
BL2 copies the OS image (BL3) to the DDR and then checks the integrity of the OS image.
In BL2, the system clock is initialized and the DDR is initialized. If necessary, uart, net, emmc, and sdcard can also be initialized.
The Process Code in BL2 does not depend on BL1, that is, BL2 will no longer go back to call the BL1 process.
The starting process of each phase is basically like this. Next we will introduce how to divide each segment of the internal memory in

Disk array is a long-standing technology on the server, it is widely used by most server OEMs to make reasonable use of space and performance in different array modes to match the cost-effective disk array. Among them, LSI Company's MegaRAID SAS products are widely used in various brands (except HP) x86 servers.Why is there a cache?Array Card core technology consists of three parts: 1, Data stripe, 2, data redundancy, 3, cache.

1. In stm32, there are five clock sources:HSI,HSE,LSI,LSE,PLL.
①HSIIt is a high-speed internal clock, RC oscillator, and the frequency is 8 MHz.
②HSEIt is a high-speed external clock, which can be connected to a Z/Ceramic Resonator or an external clock source. The frequency range is 4 MHz ~ 16 MHz. Generally, it is connected to 8 MHz.
③LSIIt is a low-speed internal clock, RC oscillator, and the frequency is 40 kHz.
④LSEIt is a Z crystal with a low-spe
