Problem downloading Appliaction code using Embedded Bootloader

[nikileshsa]

Sir,
We have problem downloading the demo application code(Wireless UART application code)into the target.We don hv the P&E multilink BDM cable....so opted for embedded bootloader.
We followed the porcedure given in Embedded bootloader reference manual.As given there
step1: freescale zigbee->test tool->test tool.exe
step 2:in menu tools->Communication settings.in list of devices click ADD internal.Here COM1 and bAud rate of 19200 wer selected.then closed list of devices.
step 3:in menu View->Embedded Bootloader->list of devices->Zigbee COM 1 appeared.clicked Ok.

step 3: Cant find device dialog box appeared..We selected the target manually(MC13192-SARD)...
step 4: List of application appeared->Demo wireless UART selected....then clicked UPLOAD.....
We got an error which read
"Timeout waiting for Download Firmware to complete!"
Please help us with this......We are also not surewhether the Embedded bootaloader code is present in the microcontroller....how to find this out.....
Thanks in advance....

Hi nikileshsa,

This is the problem with relying on only an embedded bootloader, if it breaks you have lost your window into the device and are stuck without a BDM adapter.

One way to test for this is to monitor the reset pin with an oscilliscope.

If blank or jumping off into uninitialised memory because the bootloader thinks there is code there you will see the reset pin hiccupping in response to the COP or other resets occurring.

If it is supposed to be in bootloader mode and you see activity on the reset pin then the device is blank or the bootloader corrupted!

You need a BDM adapter to re-install the bootloader.
