Because the Development Board on hand is relatively old, it is botron's netarm2410 and can only be started from nandflash. The hardware at hand is incomplete. There is only one simple Wigler JTAG. Here we recommend H-JTAG software, the latest version added support for nandflash, very easy to use.
1, first select the NAND-FLASH under the + jk9f1208
2. Click Check in the programming column to see
When debugging the H-JTAG, there will be a solution for "can't halt the target and make it enter debug state;
First: power-off, short ISP, on the lpc2400 Development Board is the jp6 in the lower left corner, and then power-on, programming several times on the number.
Second: Check the datasheet of norflash, find the address pin of norflash, connect to norflash, and repeat it several times.
Cause: Improper debugging of the H-
JTAG Pin:First, SWD and the traditional debugging mode difference1. SWD mode is more reliable than JTAG in high-speed mode2. When the GPIO is just missing, you can use the SWD emulation, which supports fewer pins3. The SWD mode is recommended when the size of the board is limitedSecond, the emulator to the SWD mode support situation1. The common emulator on the market for the SWD mode support situationJLINK
JTAG (Joint Test Action Group) is an international standard Test protocol used for internal chip testing and System Simulation and testing. JTAG is an embedded debugging technology. It encapsulates a special Test circuit (TAP) in the chip ), use a dedicated JTAG test tool to test internal nodes.

Qpst is a transmission software developed for Qualcomm chips. Simply put, mobile phones that use Qualcomm's processing chips can theoretically use qpst to

In fact, the memory in the vro consists of three parts: the header is CFE, which is actually the BIOS we are talking about. The following is the NVRAM and firmware area (the two did not study before and after ).
Many of my friends want to use the JTAG line to refresh CFE (for example, if you want to modify some default configurations, or activate memory or overclock). The speed of 8-bit transmission of this parallel port is really slow,

The recent Android project encountered a memory-crushing problem, by analyzing the log to find the memory is trampled on the address, but can not find who stepped down. Generally the problem of stepping on memory, you can use the hardware data breakpoints to find the perpetrators. But in this project, stepping on the memory is in the Android boot process occurs, too late on Jtag, the other is the RAM is dynamically allocated, each boot is different (b
