+Flash layout:
+
+0x00000 - 0x02000 - original compal loader
+0x02000 - 0x10000 - simple binary to jump to 0x10000 (jumper.e86loader.bin)
+0x10000 - ???     - NuttX binary (nuttx.bin)
+
+Using osmocon/osmoload, retrieve the compal loader, flash it and the
+jumper.e86loader.bin as well as nuttx.bin.
+
+The jumper app is a modified version of the menu app in osmocom-bb, branch
+jolly/menu. The app disabled irqs (setup by compal loader?) and jumps to
+0x10000. This app is submitted as a patch to osmocom-bb mailing list.

+Loading NuttX (highram)
+=======================
 
 The osmocom-bb wiki describes how to load NuttX.  See
