A: recently in the chip of NXP, want to go to the chip to download the program. Initially want to directly use Jlink download, tried, no (practical, may not be configured correctly). Then directly under the ADS1.2 debug, the Jlink driver loaded into the load when the driver config, direct debug can be downloaded Flash program. Toss a day, the program finally downloaded successfully (at the beginning is the Jlink driver config when there is no flash option, re-set the 4.08 version of the Flash op

Hisi hi3515 is composed of the kernel of arm9-+ DSP. You can use h264 to encode 4 d1 or 1 1080 p or h264 to decode 4 d1 or 1 1080 p. At the same time, the chip itself has a variety of peripheral interfaces uartx4 satax2 USB hostx2 sd spi lan ir I2C VGA output CVBS output and a large number of gpio, etc. On the software, the system runs Linux 2.6.24 and uses the GCC/g ++ compiler. Core board composition Hi3515 + DDR (2 Gbit) + flash (256 Mbit/32 Mbyte) + rtl8201 + resetIn pursuit of stabilit

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, In fact, if th

>_It was okay last night. I couldn't debug it this morning. When I downloaded the program, I always reported that J-link could not be connected, and the stm32 seemed to have crashed. The LED lights did not flash, and the tftscreen was not displayed. >_ I thought it was a problem with the J-Link driver, but after I re-installed the driver and restarted the computer, it still didn't work ~ At last, someone on the Internet said that boot0 was connected to a high level, so I found the boot0 foot of

I reported this error when I gave the stm32 program today. I searched the internet for a long time and found a reason and a solution. The online statement is as follows: Cause: Burned programsDisable the JTAG function.,JTAG interfaces are reused.. Solution 1: Find boot1 and boot0, lower boot1 and boot0 to 3.3 V, and download a program through the serial port. This program does not close

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. The standard JTAG in

For details, refer to the resource files I uploaded to csdn. I read them all and read the user guide, which is simple. Qpst is a transmission software developed for Qualcomm chips. Simply put, mobile phones that use Qualcomm's processing chips can theoretically use qpst to
