Download uboot to nandflash of s3c2442, using Openocd? -- Linux general technology-Linux technology and application information. For details, refer to the following section. Dear friends, have you downloaded uboot to Samsung s3c2442's nand flash? I have encountered a problem. If I use jlink to burn it, I will only burn it indirectly, that is to say, we need to first burn the data into the sdram, and then use the existing Uboot in the board to move the data to the nand flash, but there is no uboo
The fatigue driving on the PC side of the code to transplant to the board.
Configuration steps:
1. Install CCS3.3 version 81 to be patched to 82, or directly under version 83
2. Install the Xd560jtag driver.
3. Put XD560 Jtag into the board, to the board power, must follow this order or jtag a great chance to burn off
4. Installing the cgt_c6000 tool
5. Installing dvsdk_1_11_00_00_dm648

After the environment is set up, download the program to the Development Board, and then install the Nrftoolbox software on the phone
Why is it impossible for beginners to control output when using PB3 and PB4?The following is an analysis of this issue.First, after the STM32F10X series MCU is reset, the PA13/14/15 PB3/4 is configured as a JTAG feature by default. Sometimes in order to make full use of the resources of the MCU I/O port, theseThe port is set to a normal I/O port. Here's how:In Gpio_configuration (); Configure the GPIO ports used:Gpio_pinremapconfig (gpio_remap_swj_di

Today's program, according to the normal IO port configuration, found that PB3, PB4 and can not be set in accordance with the predetermined settings 1 or 0.After the Internet query, the reasons are as follows:STM32 by default, the PB4, PB3, PA15 three pins are not normal IO, but are the reusable functions of JTAG, Jntrst, Jtdi, and Jtdo, respectively.When we try the SWD interface to debug the simulation, these three pins can be used as normal IO.This

1. Connect the simulator to read and write registers.
Plug the hardware simulator into the JTAG port of the arm board and connect to the PC. Now the ARM Simulator seems to be connected to the PC through USB. After the connection, power on the board and o

As the name suggests, the system source and detector mainly contain two parts: one is the driving source and the other is the detector. Through the JTAG port, the tool can observe the status of up to 256 signals through probes,
