Hi! Does anyone know, if the Coldfire (Manual at http://www.freescale.com/files/netcomm/doc/ref_manual/MCF5206SECUM.html) supports a bootstrap mode similar to the one described in section 16 of the Dragonball manual (http://www.openhardware.net/pdf_files/MC68EZ328UM1.pdf)? If not, what is the simplest solution (from the hardware point of view) to allow the Flash RAM of an SBC to be reprogr...

We are using CodeWarrior IDE v5.9.0 for a PPC project. We need to build some additional files externally, but CW is not forthcoming with the command line it is creating in the internal project file. (.mpc) It keeps all of that and the individual object files hidden. Freescale provided an excel spreadsheet to help duplicate the command line for compile and link by telling it what IDE proj...

Hi all, I'll develop an embedded system based on FreeScale HC12, mainly using MC9S12NE64 and MC9S12DP256. In short, MC9S12NE64 - based will be a card collecting analog sensor's data, an ADC, an Ethernet port, while the MC9S12DP256 - based will be a more versatile one to develop prototype for some other future projects. I am currently looking for a development kit : SofTec inDart-HCS12...

I would like to develop an embedded device for monitoring environment parameters and send data to server via the Internet. It is not a wireless application, and it is not a smart phone application. Is Android also a good solution for embedded device, what do you think? Is it a good experience for you to develop applications with Android? I have some experience with WindRiver Workbench and ...

Hi, I am porting linux 2.6 on a custom MPC8xx processor based board that uses FEC with LXT971 on the MII bus. I am not able to bring up the eth0 interface. I have tried using both the drivers: 1. Generic FEC driver (FEC_ENET under arch/ppc/8xx_io/fec.c) 2. Freescale FEC driver (FS_ENET under drivers/net/fs_enet/fs_enet-main.c) I have posted the kernel log and ifconfig out...

I'm attempting to load Linux onto a custom board that was based on the 5485EVB evaluation board. I was able to load the BSP distribution of Linux (from Freescale) onto the eval board with few problems. I pushed colilo onto the flash and just loaded the image into RAM via tftp. That all works fine. Now I need to get this onto my custom board. The primary difference between the boards is t...

Hi all I=B4ve searched through topics and couldn=B4t find anything helpful so i started this one. I=B4m working with MCF52233CAL60 (Coldfire) and Code Warrior (Freescale compiler) doesn=B4t provide much samples. Can you point me some link or site wich has free sample programs for this chip? I=B4m looking fof, basically, tcp/ip samples like web server, smtp, telnet, ftp and other sampl...

Hi, in the CodeWarrior v7.2 for the Freescale hybrid 56800/E DSP series it is stated the IDE can program e.g. 56F8322 using the Motorola JTAG Parallel Port Converter (which, as this is a hobby project, I'm not very inclined to buy for > $200 and wait 4+ weeks for). One (inofficial?) schematic for the Motorola JTAG Parallel Port Converter is apparently at http://www.hc08.cz/attachment

I'm taking a senior design class in college (I'm an Electrical/ Computer Engineering major) and my final project is a laser tag game. My partner and I are trying to pick a good microcontroller for the guns and we're looking for recommendations. Throughout the class we've been working with the Freescale/Motorola 6811 (very old school) and writing pure assembly code but we can pick any modern m...

Hi, I am currently working on a project that requires me to interface an existing platform to an external memory, for additional storage. Below is a block diagram of what I intend to do. [PC serial port] [existing platform board] [Serial Flash] The reason of interfacing with my existing board to a serial flash is that, the current embedded flash on the MC9S08GB uC is insuffic

Hello, First of all, here is a description of the hardware. The microprocessor is a Freescale PowerQuicc8270, connected to a LSI53C1010 controler via a PCI bus, and a hard disk is connected to the SCSI controler. I need to develop a hard disk driver to read and write binary data from/to an offset on the disk. The driver does not need to be generic at all, it should only be able to read/w...

Hello, my name is Sammy. I try to write an interrupt service routine for the keyboard interrupt. I'm using a Motorola 68HC08 and freescale's Codewarrior. Port A is connected with a button. Port B is connected with LED. If I push the button, LED should switch on. If I push it again LED should switch off. I'm very unexperienced with C and don't know how to do this. #include

Not that anyone can do anything but guess what might happen, but if Microchip buys Atmel's MPU business, what is the prognosis for the PIC32. I bought some PIC32 tools and invested time learning the family, and now it may go away or new variant design activity may stop. This is because Atmel has a popular ARM based family of MPUs and the MIPS based PIC32 has only been out a year. Freescale...

Hi all, We've written an MCU-resident software development environment that we call "StickOS" that includes an editor, transparent line-by-line BASIC compiler, interactive debugger, performance profiler, and flash filesystem. We've ported it to almost a dozen MCUs (HCS08, HCS12, ColdFire, and PIC32) in the hope of making simple embedded system development easier for the casual user, and i...

Hi, I am poring from Linux 2.4 to Linux 2.6. My board is based on PPC 8270 processor of FreeScale (former Motorola). The uImage (compressed Linux kernel) size on Linux version 2.4 was ~ 720 Kbytes. What size should I expect on Linux 2.6 ? What is the typical/minimal uImage Linux kernel size , assuming that I am using TCP/IP, UART, etc. The drivers that we added are not so b...

Iam using Freescale's COLDFIRE processor MCF 5485. I have downloaded TCP/IP and USB stack which is freely available.(for coldfire processor). I plan to go for ThreadX RTOS. ThreadX has TCP/IP stack and USB stack which is NOT FREE. Are these stacks RTOS dependent ? so that i can buy only the core OR should i buy these stacks that come with ThreadX. Thanks, VIVEK

I want to use QY2 (Freescale) wich has following 4 internal adc : PTA0/AD0 PTA1/AD1 PTA4/AD2 PTA5/AD3 due to MON08 debug these ports should be used (reserved ?) : PTA0 (com) PTA1/AD1 ( high state) PTA4/AD2 (low state) so how could I debug my application if I need at least two adc port available ? Can I use PTA1-PTA4 after started MON08 mode ? Thanks. Luis
