I’m using SYS_B151.HEX from here (and it works for me): <LINK_TEXT text=“http://www.seeedstudio.com/forum/downlo … php?id=857”>http://www.seeedstudio.com/forum/download/file.php?id=857</LINK_TEXT>



Here are a few new programs you can try to get more information:


  1. Testing the screen drawing when signal capture is disabled. This skips the capture start, which seems to be where it crashes. Just verify that the screen draws correctly (albeit slowly, due to debug messages):

  2. Printing a message when first interrupt routine completes, and stop. This tells if the proper interrupt is even running, and if it is, whether it completes:

  3. Initiating a crash dump after 10 seconds. This should draw the screen red after 10 seconds and print some debug data. A photo of the red screen would be most useful; you can also post the memory.dmp from the USB drive if it manages to write one. I had to change some interrupt priorities to make the dump work, so please verify that it still hangs in the “Enabling capture TIM1” during the first 10 seconds.
