[nrf51] ADC acquisition causes Bluetooth BLE service disconnection

From the above figure, we know that if P0.26 and p0.27 are connected to an external crystal oscillator, when ADC_AIN0 and ADC_AIN1 are started for channel acquisition, BLE will be disconnected because the external crystal oscillator is interfered. This problem requires a careful look at the hardware design

How is the u-boot kernel started?

The entire program framework has been analyzed in the analysis of the start_armboot function of u-boot, but it only talks about when to run the kernel, and does not specifically explain how to execute the kernel. The kernel startup is described in the following steps: 1. Boot parameter bootcmd=nand read.j

1. NAND principle 　　　　NAND has no address space, and the transmission of address and data relies on the LDATA string of data buses. 　　　　Without looking at random page programming, you can see that the pages from high to low are divided into 64 pages in total. Each page is composed of 2K + 64 bytes. The size of a

The startup phase of u-boot is divided into two parts. The first part is mainly the start.S file. The post analyzes the meaning of each line of code as much as possible, and checks a lot of manuals. The purpose of analysis is also for learning. Writing a blog is also to leave something for my own learning. There are a
