Hi guys, I'm doing a project for college that involves porting the uC/OS-II rtos to the MC9S12XEP100. First part of the project is to get the RTOS up and running on the chip and then offload some features to the coprocessor (Xgate module). I'm in the research stage at the moment and need a bit of help to get going really. At the moment I'm working through Jean Labrosse's book on his uC/...

I need information on how to add USB functinality - reading and writing from a mass storage device (DoK). My board is a PPC based, MPC5220 (freescale) Lite evaluation board, and I'm running on a VxWorks 5.5 version. Any help or a point to where to begin from, would be very helpful.

Can anybody recommend a low cost prototyping board for ColdFire. The freescale board is too much, I only require a few digital IO and a serial port to try out compilers. Thanks.

I came across this site last week which takes eval boards and makes them web accessible. They have Freescale, Renesas, and some other boards set-up online so you can use them. And they don't even charge you to use them. I've been on an ADI Blackfin board for hours writing code and trying to learn how to use it. Has anyone else seen these? http://www.techonline.com/community/ed_resource/vir...

Hello Community, I am new to PowerPC and I have the Freescale MPC5566EVB with me for experimenting with MPC5566. I am using CodeWarrior with PENexus Micro debugger. My aim is to develop a code for FMPLL and store it in MPC internal SRAM. Then I want to boot the device from the internal SRAM. I have two questions regarding this. 1. What is the configuration of BOOTCFG for booting from 'interna...

I'm making some test with a Freescale MAC7111 on a MAC7100LCEVB. I use IAR as compiler and OSE EPSILON as RTOS. Now I have a project that is compiled righ, but when I upload the firmware to the MAC7111 the program doesn't exit from vector table initalization on CRT0.s79 someone have some idea? ;------------------------------------------------------------------------------ ;- Setup Exceptio...

Gentle Denizens: Does Freescale's HCS08 series have a vaguely unique serial number that one can programmatically gain access to? I am working out part of a networking protocol, and a canned ID would do me wonders. I remember that Temic's 8051 derivatives had a serial number that you could get at. Of course, they piled on the disclaimers about not relying on its uniqueness, etc., and th...

I am trying to find "test_app_56F801x.S" S-Record file or the source that is supposedly included with this Codewarrior IDE. (CodeWarrior Development Studio for Freescale DSP56800/E Hybrid Controllers, version 7.1) I can't locate either the source or the .S file in any of the directories. Does anyone have this or know where I can find it ? I am having suspicions that support for th...

I am using Freescale MPC5566 Evaluation board with CodeWarrior 5.9.0. I am quite new to this board and I am trying to execute a code from the MPC internal Flash. I use P&E Micro for debugging purposes. I opened a new 5566 project from CW. It automatically generated all the configuration files. I did not change any of those. I only modified the main.c file by initializing a GPIO. I use the GPIO to...

As you might of guess, I'm having some issues getting the above to play nicer together.

We are contemplating using the STM8 for a high-volume automotive application. We haven't been able to find a good end-of-line programming solution. We typically program our microcontrollers after the circuit boards are fully assembled. For the Freescale parts, we've been using, we had good luck with P&E Micro's Cyclone Pro: http://www.pemicro.com/products/product_viewDetails.cfm?...

Hi to all. I can't seem to get the eeprom emulation on a mc9s12C32 to work. I have the App note AN2303/D and associated files from Freescale website , but I am still struggling. I am new to this processor and have never done anything like this before , so excuse me if I am being a bit of a "dumbo" :0( I have created a basic project using the "Processor Expert" function.

We are using the Microchip MRF24JA40 802.15.4 RF transceiver, might look into Atmel's AT86RF231 and Freescale's MC13202 as well. We have one working board talking to a Microchip pre-made module, but two non-working boards. The only difference is the crystal. The working one is 5 mm SMD and the non-working one is 11 mm 2 pins. Could it be so sensitive to crystal selection? Do we need to p...

How do you compare ARM MCU manufacturers for a project in the USA? I see Atmel, St micro, nxp, Texas instr, Freescale, Marvell - are they all selling the same stuff or is there any real difference? I see St has faster parts but Atmel has more of them. Is price and support all the same? Google doesn't seem to show any information anywhere on this, which is really shocking. I am wonderi...

Does anyone have recommendations for Cortex M3/M4 microcontrollers with a bootloader in ROM? We use a number of Freescale Kinetis devices, but there is no ROM bootloader - programming is through either JTAG or the EZ-Port (basically treating the chip like an SPI flash device). We have an application where a UART-based bootloader would be very useful, and having it in ROM would save a lot of...

As a complete noob at embedded development I'm looking at the FreeScale Netburner (5213) dev kit as a relatively capable processor and reasonably priced entry into the game, but with the pricing on the 5270 being effectively the same for twice the bang for the buck, I'm not sure how to proceed. The ram/flash size make either one appealing, but of course more is better, right?? The ...

Hello I'm looking for two microprocessors, one that optimized for Java applications and another that has a compressor MPEG4. I need to do two designs, one with uClinux running an application in Java (requires a lot of time porting to C), another who has uClinux and it has to compress into MPEG-4 video input. For MPEG4 I found the series of Freescale i.MX, looking at Datasheet but I find no...

We're looking at converting a PCB from 6805 to 68H08. Freescale (Motorola?) have a document that says the H08 is enhanced "fully object code compatible" version of the 6805. I suspect this just means that the opcodes for e.g. BRA somewhere, are the same in H08. I know most H08 instructions execute faster than 6805.. I will read the manuals in detail to compare but I'm wondering if any...

Hello All, I'm building a small vehicle that uses a couple of optical sensor as navigation. There are two MCUs, both Freescale HC08 family. The motors are just small 5V DC brush ones that's been driven at 7.0V, PWMed to 70% (PWM Frequency 800Hz). There are two motors for a differential drive setup. I'm measuring a total idle current of 800mA on the motors, the load current is about ...

Folks, We need to store some non-volatile parameters across power-ups and I'm trying to determine how to programmatically write to FLASH in the MCF52235 Coldfire V2 processor (256KB). From the reference manual it looks like reads from the ENTIRE FLASH are disabled when updating (erasing/programming) any part of the FLASH, even if you're just updating one of the 32 8 KB sectors. But I'm not...
