NXP NXP P89v51rb2/rc2/rd2 single chip decryption chip hackThe P89v51rb2/rc2/rd2 is a 80C51 microcontroller that contains 16/32/64kb Flash and 1024 bytes of data ram.The typical feature of P89V51RB2/RC2/RD2 is its X2 mode option. With this feature, the design engineer can enable the application to run at the clock frequency of the traditional 80c51 clock frequency (which consists of 12 clocks per machine cyc

NXP Semiconductors, formerly known as Philips semiconductor, has announced that the company uses a full range of transceiver products using WiMAX 2x2 MIMO (Multiple Input Multiple Output, Multiple inputs and Multiple outputs) technology, this series of products is specifically designed for mobile and handheld applications. To fully support the adoption of mobile WiMAX technology, the new series of NXP Semic

1). Introduction MQX is a real-time operating system provided by NXP, with the following diagram showing the kernel, file system and protocol stack, as well as good support for NXP's arm processor, which can be easily developed and deployed. This article demonstrates compiling and deploying MQX applications based on the Toradex Colibri VF61 (NXP VF61 SoC) Arm computer module paired with the Colibri Eva Boa

How GPIO is configured for Freescale IMX6 processors Turn from: Http://zzjlzx.blog.chinaunix.net/uid-9688646-id-5206540.html In Linux or Android, if we want to configure a Freescale IMX6 processor's Gpio pin, such as the gpio_19 pin, then this: [CPP] view plain copy #define Mx6q_pad_ Gpio_19__gpio_4_5 \ (_mx6q_pad_gpio_19__gpio_4_5 | Mux_pad_ctrl (No_pad_ctrl)) Where _mx6q_pad_gpio_19__gpio_4_5 is defined

In Linux or android systems, if we want to configure the gpio pin of the feisikar imx6 processor, for example, the gpio_19 pin, we should look like this: #define MX6Q_PAD_GPIO_19__GPIO_4_5\(_MX6Q_PAD_GPIO_19__GPIO_4_5 | MUX_PAD_CTRL(NO_PAD_CTRL)) _ Mx6q_pad_gpio_1920.gpio_4_5 is defined: #define _MX6Q_PAD_GPIO_19__GPIO_4_5\IOMUX_PAD(0x0624, 0x0254, 5, 0x0000, 0, 0) The iomux_pad macro is a key macro defining gpio. Its prototype is: #define IOMUX_PA

For a given data, the access bit for the end of the zone is 0 0 1, and you can see that only key A can be used, the key Keya but not readable, the access control bits and keyb can be read and written. 2) Access conditions for data segments (access conditions for data blocks) 1 if key B can be read at the corresponding end of the zone, it cannot be used to confirm (all gray rows in the Access condition table in the end of the zone).

In the use of IMX6 Core Board development, the program written to a U disk, want to run the program on the board through a U disk, U disk inserted on the board after the minicom in the information display, but unable to find the Mount file,/dev and/mnt did not find the corresponding file. Baidu later found that the U disk in the arm of Linux needs to be manually mounted. Here's how:1, the USB stick will be inserted after the information displayed in t

1. Adopt slave mode2, SS_CTL configuration is 0The configuration instructions for this bit in imx6 are as follows:whichIn slave Mode-an SPI burst was completed when the number of bits received in the shift register isEqual to (BURST LENGTH + 1). Only the n least-significant bits (n = BURST length[4:0] + 1) of theFirst received word is valid. All bits subsequent through received word in Rxfifo is valid.Follow the following two sentences:If BPW is set t

In the process of using imx6q spi5 (spi5 I added), I encountered a problem: 1) The upper app sends 3 bytes of data to Spi5 via Write () , uses the oscilloscope to capture its chip selection signal, as shown in: 2) The same driver, the upper app sends 3 bytes of data to the SPI2 via write () and uses an oscilloscope to capture its chip-selection signal, and then the slice is pulled higher after each packet of data (3 bytes) is sent. 3) on the Freescale's official website https://community.fre
