freescale kinetis

Kinetis provides a fairly reliable mechanism for protecting intellectual property rights; It is necessary to lock the chip artificially, which is a product of postpartum. However, the user mistakenly erased the chip internal Security Memory part (0X400~0X40F), thereby locking the chip; is the chip going to be scrapped, in fact, there is a way to save. Once the chip is locked, that is, J-link and other debugging tools can not download the program, i

1, install J-link Drive.With the J-link driver in the KDS installation directory, enter the following directory (in my case):C:\Freescale\KDS_1.1.1\segger\USBDriverwill see the CDC, x64, x86 three folders, according to their own system to choose the corresponding program, only two steps (in my case):1> Enter the CDC folder, run Dpinst_x86.exe, and wait for the installation to complete.2> into the x86 folder, run DPInst.exe, and wait for the installati

Many of my current active projects are using NXP's Kinetis Design Studio (KDS) V3.2.0 (I've published a lot of projects on GitHub). Now with the advent of the Mcuxpresso IDE (see "Mcuxpresso IDE: Unified Eclipse IDE for NXP ARM cortex-m microcontrollers"), I've migrated several KDS projects to Mcuxpresso. This article is about how to easily migrate KDS projects and run them in the Mcuxpresso IDE.OverviewThe Mcuxpresso IDE uses a newer Eclipse IDE (Neo

This article describes in detail how to migrate the NFC Reader library to the Kinetis k64f microcontroller. This article uses a real-world porting case to demonstrate the steps required to migrate the NFC Reader library to the sample target MCU. The purpose of this article is to serve as a guide for software developers to transplant the NFC Reader library into the MCU chosen by their design. NFC Reader Library Overview The NFC Reader Library is a se

For CMSIS function calls, ARM officially provides stm32 examples, and it seems that there is no problem when stm32 calls CMSIS. Problem Source: see iar technical article Using CoreSight Trace Techniques on Cortex-M3/M4, I feel good, one by one practices on kinetis, found Example 5: the functions described in Printf via SWO cannot be implemented. Problem Analysis: The function ITM_SendChar () cannot be called. The function is defined in the core_CM4.h

Before Yan Freescale series single-chip microcomputer is the flagship product developed by feisikar. The former Motorola semiconductor department is one of the world's largest semiconductor companies. It has four R D centers in Beijing, Shanghai, Suzhou and Tianjin, we have established Freescale single-chip microcomputer labs and training cooperation institutions on more than 20 key university campuses in

Patch and Crosstool-ng can be downloaded from the following URL, https://community.freescale.com/thread/386450 but you will be disappointed, changed the script, compiled and found that the wrong, LD,GCC version is not correct,There is no way to reproduce the environment of Freescale, compile the same toolchain, the same toolchain is how to compile, estimated that Freescale is not known.It took a while to re

First, we need to understand a basic concept: the geomagnetic sensor must work with the gravity sensor, and the compass will work properly.I. Key points for commissioning:1. The gravity sensor has a directivity of 3 axes, and the data output of the geomagnetic sensor is also directional. We must configure the correct position according to the position of the relative LCD view of the hardware Layout board sensor to indicate the correct orientation.2. Mag3110 driver in the Linux bottom register, i

The low-cost Blackfin Processor ADSP-BF531 of ADI and the multi-media processor I. mx21 of Freescale Silicon Valley semi-analytics are both very user-friendly. ADI ADSP-BF531:1. Three points: low power consumption, low bandwidth, and great startup for vdsp.2. bf531 chip functions are quite rich. What is the supported audio/audio format package? SPAN href = "tag. php?

This year's merger and sale of the semiconductor industry have just ended, and they have just begun. First, the split of PHILIPS semiconductors, which was widely spread at the beginning of the year, was completed last month. Then, Intel sold the Non-Profit department twice, which can be described as a scissors. Now, Freescale, just two years after its independence from Motorola, was acquired by a consortium at a price of $17 billion, which is $40 per

Freescale ATK (advanced toolkit) is an embedded system flash burning software designed for its MX series CPU core. It can be used to burn Bootloader and kernel to flash. (Nor, Nand, MC/SD ...). The principle and workflow are as follows: First, set the jumper to UART/USB boot. Then, after the Board is powered on, the ROM in the SOC starts to initialize the internal RAM and waits for data on the UART/USB And load it to internal RAM. Then on the h
