Debug RCE applications with the Multi-Function-Display
Each RCE has 2 8-character LED multi-function-display (MFD) chips on the front-panel (4 MFDs per board, since there are 2 RCEs per board). The first of these two is controlled by powerPC software in the FX60: it displays the value stored in a DCR register. The second is controlled by firmware in the 4 FX20 FPGAs (2 characters per FX20).
...
Where <filename> is the file name, in the local UNIX file system, of the ELF file which is to be stored at image number <imgnum> in the RCE configuration flash memory. Note the image number must be between 1 and 15. Image 0 is a protected "safe" image that can only be programmed via the JTAG cable. You can then use the bootcfg command described in the console command line above to make the newly flashed image boot-able from the RCE.
