Hi, A few years ago, we developed a board using the TMS320F2802 to a customer. It was a small manufacturing batch only. Today this customer called and asked for more 10 boards to replace some boards that went bad due to a huge power surge. The problem is that we don't have the codes in our computers anymore as it is an old project, but we still have the first prototype we made and is is not firmware protected. I know there are a few JTAG devices that can read the firmware and use it to program the other boards, but I am looking in a way to achieve this using the XDS100 we already have. Do you know it is possible? --------------------------------------- Posted through http://www.DSPRelated.com

You probably should, as part of a project, make *them* escrow deliverables, including a JTAG device and a document that details how to reinvent one step by step. I recommend at least three levels of backup: a NAS in your office ( on a UPS ), a backup set ( USB drives are awesome for this ) at somebody's house and a USB drive in a safe deposit box. Refresh all media annually. If you don't wanna ship code, then at least a hex file, S record file, whatever the JTAG consumes. You really need to do this to where you can reproduce them for scratch. And you should have them pay maintenance for this. It doesn't have to be much. These days, you might be able to install the development tools on a virtual machine and simple archive the virtual machine. You *should* be using source code management like git or SVN. Virtualbox allows for sharing folders with the host O/S so you may not have to share the USB device under Virtualbox - which may or may not work. I cannot speak for the XDS100 but for the Microchip IPE ( not IDE - IPE ) , there is a button that I have never used that claims to pull the contents of the FLASH. Ping TI support. -- Les Cargill

When I retire a customer, the entire "technical" directory for their project gets copied onto CD's to be archived here, and, if the customer wants, another set for them to archive. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com

It was a retired customer and we have a DVD backup, but it the disc is not readable anymore. The disc layer is "peeling" off... For the Microchip and Atmel, it is easy do, like you said, just need to hit the read button. But for the TMS320, I cannot see that option. --------------------------------------- Posted through http://www.DSPRelated.com

The backup DVD is unreadable. And is was a retired customer. Any tips? --------------------------------------- Posted through http://www.DSPRelated.com

You may have to bite the bullet and get that JTAG device. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com

I have yearned to also store data off-site but haven't found a convenient and economical way to do so. -- Randy Yates Digital Signal Labs http://www.digitalsignallabs.com

If my shop burns down I'll lose old data, but otherwise not. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com

They are cheap, sometimes free and tax deductible (so a friend told me). -- Rick
