Hello Folks, Looks like I'll have to debug code for a small uC (MSP430) in the field pretty soon. Cramped space, things can be banged around a bit, the usual. What would be a small, low cost and bare minimum laptop to do that with? Or is there a nice PDA where a keyboard can connect to? The programmers work via USB. The bootloader I may have to provide would be RS232 but that could b...

If you are looking for a good bootlaoder for your new hardware... then I am able to help you out with porting u-boot to your platform.. Only requirements: - Available toolchain for the platform...either free gcc/binutils or commercial package has to be supplied. - Sponsoring of at least 1 target platform for the porting service (quantity depends on the complexity) For more d...

I'm planning on making the move from PIC to AVR for my next project but I'm running into a very frustrating hurdle. I'm having trouble programming my AVR butterfly over serial using the bootloader. The wiring seems very straight forward, 3 wires pretty sure that is ok since there's pin numbers in the manual and I can read the pin numbers right on the cable. On the butterfly side I put the ...

Hi all , I have just designed a board with a JTAG interface and ISP interface ( with some good advice from past discussions on this forum)and have also bought the JTAG programmer. Now before I send the board for layout , I am looking at the nitty gritty of bootloading a hello world programme ( flashing leds!) on it. Does the ATMEL parts come preprogrammed with a standard bootloader in the...

Hi I have a portable recording device from Boss that I'd like to reverse- engineer a bit. They've made firmware updates freely available on their web pages. What information can I extract from those images? I'd like to know micro-controller model, compiler and used OS. The update contains 3 .bin files, one of which is bootloader. I've extracted all strings from images, and gained little i...

The first thing to think of is the firmware upgrade strategy of an electronic device with embedded software. There are a multitude of bootloader out there for different microcontrollers, physical communication links and features. I know it's difficult, but is there a somewhat standard firmware upgrade procedure/strategy/protocol? Some open approach that is followed by different vend...

Hello. I'm having a bit of a problem writing a bootloader for the Renesas H8S/2314. The problem seems to be that i'm unable to write to the flash memory. So far, the problems seems to be that i'm unable to assert the FWE bit, however i'm able to program it using the Flash Development toolkit (so it enters bootmode, which implies that the FWE bit is asserted). I've put a switch connected to ...

I've 'inherited' a custom board (with schems and datasheets etc, thank God!). I've never done any embedded work at all really and I've been having a play with this, with a little success. What I have a is a custom bootloader (S-Record, no source) and a RAM loader tool for the board. As I understand it, I basically set the board to Bootstrap and the RAM loader is a set of Bootstrap Records ...

I'm designing a small electronic gadget with a USB device port. Now I'm thinking about a good method to upgrade the firmware through the USB. The process should be as simple as possible for the user. I think there are three main method, each one with pros and cons. In all of them, the user should only press a button while the device is connected to the host (so powered up). At startup, ...

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...

Does this chip come pre-programmed with a bootloader? It seems from the datasheet that all thats needed to program it (in-system) is the use of Atmel's FLIP software, and no mention of any hardware requirements (PSEN, etc). Is it that easy?

[Xposted to comp.arch.embedded - hopefully there are a few H8 asm gurus there who can help] Hi, I'm currently trying to reverse-engineer the LZSS decompression engine used in the Cybiko PDA to compress firmware updates (and small ASM and C programs) that are sent over a serial link. I've disassembled the bootloader and found the decompress() routine (in Hitachi H8 assembler), but ...

Hi, My earlier post was: Creating multiple images (Boot & App) in a project (IDE: CCS/IAR/CrossWorks) ? I am working with: Microcontroller: MSP430F1611 IDE: CrossWorks for MSP430 Right now I have managed to create and load the 2 images, namely, Bootloader and Application, in separate memory locations. And I am able to jump to the Application code by using the address of its "main...

Hi, I have an application whose DataMemory clashes with the DataMemory of my Bootloader. So, I have thought of shifting the Applications Datamemory mapping. Now, i have rempped it. But, When my application starts, the the MMU is disabled & The MMU is enabled inside the application only. So, there is a situation that my stack will be pointing to one location when the MMU is disabled and...

I have a board based on the AT91RM9200, and want to boot from SPI dataflash. The loader will proceed to boot u-boot (Which is too big for the ROM bootloader to handle). I have read the atmel appnote on that, but boot program will need to be changed. My SDRAM is configured differently than the DK. The program with the appnote includes source, but it is missing quite a bit to be able to be ...

We have a number of systems based on the ppc core in a Virtex 4 FX12. The system has 4MB flash RAM for program storage and 32MB RAM and uses one of the EDK-supplied Ethernet cores for comms (temac). Some time ago I ported a 2.6.15 kernel onto it and we've been running with that ever since. The system boots with a small bootloader which loads uboot which in turn loads the Linux kernel. Th...

Hi all, I have "inherited" a project with a H8S/2633F MPU (using the GNU gcc toolchain). I need static variables. Problem is that there is no init code for static variables in the bootloader code. I.e. the initial static data is correctly placed in the FLASH ROM, but the data is never transferred at startup to the RAM. I have searched everywhere for a simple example showing how to do it bu...

I have written an ARM920t assembly code for serial port access on smdk2410 board. I have compiled it using arm-elf-gcc which does not require any underlying OS. How can I Port it directly to the RAM to make it executing without any bootloader or OS present. And also do I need to make any hardware initialization prior to initializing the UART.
