I was wondering how people handle a firmware change in the manufacturing process. One thing we are considering is issuing a new part number for every firmware release. The number may be a "Rev B" or some extension of a base part number, but it would be unique for each firmware release. Then, when a unit is built, it must use a certain "part number" that is really a firmware release, prob...

Hello. I am implementing a program to be updated via GPRS channel. The total size of the firmware reaches about 256 kB which makes it somewhat costly upgrades. I considered the idea of dividing the firmware into independent parts that can be updated independently and upgrade only the changed parts, but I don't know how to begin. Does anyone has had a similar problem? How do you have solved it? ...

I've googled and dead-ended on this one, maybe someone in this group can help. I have an original TDS210 digital scope with the original V1.0 firmware and the Communications module is V1.02. I have used other TDS210's with newer firmware and I want to upgrade my V1.0. I want to do this myself so does anybody know what is required to upgrade the firmware for this unit? TIA *Peter* ...

I want to understand more on firmware, embedded software, and embedded systems. My understanding is that firmware has programming instructions burned in a chip, which is a ROM? And once we burns it, the information is read only. For example, the chip inside smart card is a firmware?? Embedded software consists of more than one firmware?? Embedded system is a computer system in large h...

Hello all I need to run an old firmware for a Siemens SAB 80C537 microcontroller unit (MCU). The MCU is now obsolete (it's from the late 1980s). The firmware is compiled from several thousand rows of assembly language. It would take a long time to understand the code and re-program it in C. So I'm thinking of using an 8051 IP-core for a FPGA and run the firmware code wit...

Hi all... I have following problem. When I wanted to debug my project written in IAR 4.2 using Olimex's JTAG ISO, a message popped up saying something like Olimex firmware version is not supported and it offered me to update firmware. I said no, but I could not download my project. I tryed again but this time I said yes when he asked for firmware update. After that I still can not download my pro...

I am building a widget. Management wants to have several tiers of capability which are all firmware enabled... meaning the hardware is exactly the same just certain capabilities are 'unlocked' in firmware. A typical scenario would be the end user purchases the base widget. A year down the road they want to upgrade to the widget plus model. They would purchase from us a unique 'key' which could be ...

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...

I am just learning about Microchips's bootloader capabilites. What is not clear from any of the documentation I've read is whether the chips with bootloading capabilities ship with the bootloader firmware installed. Some posts in this group indicate that you have to add the firmware yourself with an ICSP, which of course requires a hardware programmer and the corresponding software. This m...

I have an Atmel AT89C5132 that has some USB mass storage firmware. It uses the Windows USBstor.sys Mass Storage Class driver. I need to be able to keep that in place an still be able to send data from a desktop application to the chip that will get passed on to another processor. I need help understanding where I can safely modify the firmware, knowing what to look for (CBW or CSW etc), and ...

I am trying to implement the in-circuit firmware upgrade feature on a MSP430148 based system. The firmware consists of a boot loader and application. boot loader will be able to receive new application firmware over UART and program it into the flash to replace the older application. I have a few questions related to this: 1. Can the boot loader program flash while executing in flash? Or do...

Hi, I would like to request some help in understanding the relationship beween firmware and device drivers. My understanding of firmware is software that is generally stored on the ROM/EEPROM/flash of a device controller and performs specific functions pertaining to that device. But a device driver also helps the user in interacting with the device. So how does the functionality of the devi...

Hello, All! Could you please clarify the definition of 'firmware' term? I always thought it's only bootloader, but recently I've found it's much more deeper, so I'd like to understand more clearly this. With best regards, Roman Mashak. E-mail: mrv@tusur.ru

Has anyone experienced having their JTAGICE firmware accidently erased? I hook up the emulator directly to my PC today with no target board. Then ran AVRProg.exe and erased. AVRProg.exe showed SUCCESS! Now the 200 dollar question is, how can I restore the firmware? I cannot do any debugging or ISP programming with my JTAGICE now! Thanks, Steven

The chip (SIM ?) inside the smart card is considered as firmware? My understanding is that firmware means software on ROM. Or can we say embedded software? I am confused with those terms. Please advise. thanks!!

I'm currently searching the coder (firmware) who has experience with I2C bus. I am looking for firmware solutions for my prototype that will be used in manufacturing testing for I2C LED Modules. Each module contains six of TPIC2810 LED Driver chips with Address from 1100000X to 1100101X. All of 8 outputs for each LED Driver are loaded with LED. I need to use LED Display Module for di...

Hi, I dont know if this is the right forum to ask but I would like to know what is firmware testing is all about. I have been asked if I am interested in this but have not worked in this area before(I am from hardware background) so please let me know of any links or sites which can give me an idea. thanks, Neo

Hi, I have a Cypress EZ-USB FX2 USB mass storage device. AFAIK firmware is only allowed to be downloaded to either the external EEPROM or internal RAM when the device either 1) Does not have an EEPROM, or 2) Has an empty EEPROM without any existing firmware When this happens, the host PC will load the Cypress generic driver(Cypress FX2 - No EEPROM(0x8613) rather than the default USB Ma...
