I am looking for a piece of software that would sit in the boot sector of a hard disk and load an application thus making possible an embedded application without having to use an OS. Source code is needed. The application will be coded in C or C++ using the GCC compiler. please reply to this newsgroup. Thank you

Hi people Well here I am. I have never tried work with bootloaders before so I thought that news groups might would be a good place to start as all the old school experts hang around here :o) One of my problems are that I need to fit alot of SW down in to a 1MB flash. So i'm looking for the possiblity of compressing the binary file and then extracting this into the RAM(2MB). How can this...

Hi all, I am a newbie of ARM embedded programming, only worked with ARM mcu for a little more than 3 months. I had a problem that at this stage am unable to solve and would appreciate if anyone can help or give suggestion. In my application, I had a bootloader that, on device reset, it detects on network (via Lonwork's MIP) if the axf inmage should be updated. If the axf needs update, th...

Hi, I read in the datasheet about that by means the so called DFU is it possible to bootload when the STM32F2xx act as USB device. Anyone has hints or links about how to bootload from a pen drive using STM32F2XX as USB host ??? Many thanks

Hi All, I want to move to something bigger than a Z80/8032/PIC which I use at the moment. I would like about 50 MIPS, 1MByte Flash, 256KByte RAM - possibly all external, integrated ethernet, 2 serial ports, enought DSP capability to do 2 or so channels VOIP, the ability to self program (bootloader) for remote update. I have looked at ST, Freescale and Rabbit. The rabbit seems to be alm...

Hello, I wonder if anyone makes something like Parallax did with PIC, but populated with ARM ? Anyone selling DIP40 device with ARM and FPGA and ethernet? With bootloader, RTOS and interpreter for fast prototyping? Digi has Connect ME device, but it is not DIP and anly 5 I/Os and UART from the ARM device is accessible. Lantronix has Xport with 3 I/O and UART and they are releasing new...

Forgive me if this is a noob question, but this is my first chip bringup from scratch. I'm trying to bring up an ARM7 (ADuC7021), and am having a problem with the endianness of data, and I'm not sure how to fix it. My problem is this: if I call an internal function SD_OutputString("Bootloader.."), I get the following output on my serial port: "tooBdaol..re". In other words, it seems to...

Hi there, I'v got the following problem: I've got a C164CI microcontroller (Infineon) and I've written a prog to send Hex-Files to it. When I work with the integrated OS of the microcontroller I always have to add '0xFF's to every record that has less than 32 byte. Now I'd like to write my own bootloader for the microcontroller and my question is: Do I always have to fill my hex records ...

Hi, I am a beginner at using the atmega chip. I am using codevision to compile, AVR bootloader V2.1 to execute my program, but for troubleshooting, my AVR Studio 4 is not working correctly. When I open my project to debug, it does not list my source files. I want to be able to step through my program and check where it breaks. I seem to only be able to see the disassembler. I can open my...

Hello I'm going to port bootloader U-Boot on a ARM based platform (arm926ej-s specifically), my final goal is to lauch Linux on my board. I worked with arm7 CPU before, although this is my first experience with U-Boot. Now I'm gathering information on it. Many MCUs built on arm7tdmi core (for example, SAM7 family from Atmel) involve remapping, i.e. 0x0 address points on ROM at reset ...

Hi Im new to ARM9 processors and have the following problem: i want to run any executable code (that i can change) on my plattform. So i found the Denx u-boot and can compile it. Then i tried to download it as stated on the atmel page by setting the jumper to INT then load the DataflashBoot.bin then load the u-boot to the dataflash. So far OK, can see the u-boot image at position c0008000. Wh...

Hi everyone, I am very new to Embedded Linux. I know that the MMU handles all of the address translations from Virtual to Physical. My question is that how does the MMU know which physical addresses actually have RAM? Is this information provided by the CPU? Kernel? Bootloader? For example, if I have a board with the first bank of 64MB DRAM mapped to 0xa0000000 and second bank of 64MB DRA...

Greetings Title says it all. My company is using PIC10's as local supervisors, but they are a pain in a number of ways that I don't wish to discuss. We would like to know of micros that have UART bootloaders loaded at the factory so that the parts can be programmed in system from a serial port on the test computer. Requirements are simple: 8 bit ADC, a few timers for PWM. Cost is

I'm building an AVR-based machine controller for a customer, and he has asked if I can make the unit upgradable from a PDA. The end-user wants to read/write EEPROM setup data from a handheld device (they're currently choosing between Palm or WinCE) and for this purpose I added a serial port and simple comms protocol in the original design. Now he wants to be able to upgrade the firmware over ...

Hi, I'm developing an I2C slave device based on a MSP430F169. Another 'F169 is the master (for testing) and every now and then, the communication breaks down. The master's application is derived from TI app note slaa208 "Interfacing an EEPROM to the MSP430 I2C Module". I'm implementing a I2C bootloader for the slave device, and the control flow goes like this: 1a) Master does "ack-...
