SAM-BA 2.15 Hangs after identifying board

I have erased the flash with the erase test pad on the xplained pro board but I am not ever able to get into SAM-BA it seems. Any ideas?

Edit: on another run it stops at the sourcing board description file line.

Edit edit: SAM-BA on windows is able to open up and read the chip's memory.

I am having an identical problem, however, my Windows system cannot get by this either and reports via a popup dialog that the applet never returns.

This happens when I run the demo script:

^C

I'm using the sam-ba_64 on Ubuntu. I am able to screen to /dev/ttyACMO, jumper the the boot_dis pins, then reset and see the string "BootROM". I get out of screen and then invoke the script or sam-ba_64.

Were you able to find a solution to this issue? Or does anyone else know why it would hang here?

Is this EK board powered by a wall-wart or just through USB?

Thanks for the reply, for some reason I didn't get notification of it. The answer is USB only.

I surmise you're thinking I should use an external power source.

I surmise you're thinking I should use an external power source.

Yes. Apparently the Xplained boards can run off just USB power, but not the big EK boards.

• 1. Apply external +5VDC.
  2. Disable flash chip selects, e.g. remove jumpers and/or hold-down push-button. Remove any SDcards
  3. press&release reset button. (If you have a DBGU connection, you should see a "RomBOOT" and nothing else.)
  4. restore chip selects, e.g. install jumpers and/or release push-button.
  5. connect target's USB Device port to host PC.
  6. execute SAM-BA on host.
