External debugger for BeagleBone

Other Parts Discussed in Thread: TMDSEMU560V2STM-U

Hello everybody

I have been writing software for the BeagleBone board for a while with the on-board debugger, and everything has been working fine. Now all of a sudden I am getting strange behaviour from the debugger, it seems as if the problem is with reading (or writing) of the external RAM.

I am considering buying the debugger TMDSEMU560V2STM-U and using it instead. Does anybody have experience with this?

Thanks

This JTAG emulator should work fine. Make sure you set it up for 3.3V. Also note, that you will need to modufy the BeagleBone and install the header in order to use the emulator.

For information exchange with others who have done this, you may want to check the beagleBoard.org discussion group found at https://groups.google.com/forum/?fromgroups#!forum/beagleboard

Hi,

Just adding to Gerald's reply, can you copy to a .txt file the memory access errors you are seeing and attach them to your post? If you also have a screen capture with the errors and a detailed description on what you are doing when the error happens, that would help.

Cheers,

Rafael

Here is a screendump of the error I get in CCS. I have read several places that it could be a problem caused by the FT chip resetting the board, however i removed R163 on the board and also tested with other revision, but still get this problem.

It turned out that there was a problem with the watchdog. Every time I paused the device, and stepped through the code, the watchdog still managed to reset the device.

After disabling the watchdog timer (when in debug mode), everything is again working perfectly.

I followed the information about the Blackawk debugger, and it is also working fine.
