Re: TRX2a Serial Problem

If I have corrupt bootloader code can I reload the bootloader hex file using an ICD2 and then use the bootloader to reload the operating program hex file - or do I need a special first time load hex file that contains both the bootloader and the operating program? If I need the combined file where c...

Re: TRX2a Serial Problem

Thanks Adrian. I just tried it with the Win7 computer and a real RS232 port with the same result. I originally had no serial, found the ST232 IC in backwards and replaced it with a new one. Now the normal serial stuff works okay but not the boot loader. I suspect that the boot loader has been corrup...

Re: TRX2a Serial Problem

Tried the dual usb-serial adapter on my laptop. Software recognizes it and a loopback test shows the software outputting "U"s but still no reponse from the TRX2 bootloader. Tried sending "U"s with HyperTerm and no response there either. But, HyperTerm works with the RS232 test mo...

Re: TRX2a Serial Problem

I've been doing some playing here with an XP machine with a real serial port - but don't have my TRX2 available at the moment. The boot loader doesn't recognize my Belkin F5U409 at all either. It does recognize a Manhattan dual serial-USB converter. I hooked up a null modem cable, put a serial monit...

Re: TRX2a Serial Problem

"It only times out if the host boot loader isn't trying to connect when I power up."

Thanks - good info. That confirms what I was thinking, that the host is somehow not communicating with the USB-Serial adapter even though HyperTerm does.

Re: TRX2a Serial Problem

Yes, I did replace the XML file. I can't leave the TRX2 in "boot loader" for more than a few seconds because it times out and goes to the normal radio mode. I looked at the Ingenia documentation on their web page and see that the software should start by sending "U" characters to...

TRX2a Serial Problem

My TRX2a is having problems with the boot loader firmware upgrade server - I think. The computer is an XP laptop using a USB-Serial converter (with a FTDI chip). Using HyperTerm I see the log on messages when the TRX2 is powered up. The RS232 test mode is working correctly. When I run the upgrade pr...
