+RedBoot support is available for the JTST board. 
+By default this board is shipped with 256Kbytes of
+external SRAM. To minimize the amount of RAM used by RedBoot, only very basic
+flash management is provided, comprising of just the <command>fis
+erase</command> and <command>fis write</command> commands.
+</para>

+RedBoot supports two serial ports.
+The default serial port settings for RedBoot are 115200,8,N,1.

+<title>Installing a RedBoot image on the JTST</title>
+<para>
+This development board comes with RedBoot installed on flash. To
+install a new version of RedBoot or another binary image in flash you
+must start a GDB session setting a remote target and load and run the
+<command>jtstflashd.elf</command> diopsis application. This is a
+daemon that listens on JTST serial port 1. On the PC side you must use
+the <command>jtstflash.exe</command> (both linux and windows PC are
+supported) to flash the image on JTST.
+</para>
+<para>
+When the jtstflashd.elf is started, the user should open the jumper
+JP5 to write in the second half (512Kbytes) of the flash, in this way
+the original RedBoot image is preserved.
