Stuck in X-CTU mode

Posted by SimonK at September 05. 2008

Hello Makers,

While working with XBee modules I find that shorting the erase pins on my Make board no longer works. In MC Helper the board is listed as USB(COM6) which is correct, shorting pins & re-powering makes no change. Board works as normal in X-CTU

I have another Make board which works fine,same machine,same port,same usb cable, same software. (Win XP)

So, has some component gone on this board, any ideas?

Thanks

Simon

Hm - I haven't heard of any boards losing the ability to go back into sam-ba/erased mode. There are no external components that have any bearing on this - it's just right on the chip itself. Can you check that there's definitely a good 3.3V signal on the pin right next to the ERASE pin - the one you're shorting it to? Perhaps try uninstalling/reinstalling the USB driver?

Thanks for the reply Liam,

I measure 3.25V (USB power)

I have previously uninstalled/re-installed the usb driver. I have another board that works with this system (PC) & I have just tested on my MacBook Pro (OSX 10.4), same result, stuck in X-CTU, which btw works fine, will communicate with XBee modules.
