I tried various combinations of power, battery removal, and whatnot while jumpering across the "USB BOOT" switch contacts. No luck -- it behaves as before. Online docs say to connect USB to imx_usbdownloader on a linux PC, then apply power while pressing the USB BOOT switch, but I have not had success. No 15a2 VID I am looking for (only 1949:dead from lab126, or nothing). I wonder if those ON/OFF pads disconnect power, which may be easier than futzing with the battery AND USB cable (which also may supply power) while holding a jumper across "USB BOOT". Better still would be to find and install some push buttons. I have a bag full of dozens of those tiny push buttons I got off ebay, if only I can find them...
