/* If you make any chnages to this file, then you must take the following steps.
**  1) compile and upload this program to FRDM-K64F
**  2) reset FRDM-K64F and wait for green light
**  3) connect FRDM-K64F and IPCU 2 to the same Ethernet switch
**  4) gain access to the IPCU 2 u-boot prompt
**  5) type 'run upenv' and press Enter
**  6) wait for green light
**  7) type 'run chkenv' and press Enter
       notice that there is an error, for example "byte at 0x0100033b (0x62) != byte at 0x0200033b (0x63)"
**  8) type 'md.b 2000x00 100' and press Enter
       replace the x with the base address in the error message
       in the example above the error was at 33b, so enter 'md.b 2000300 100' and press Enter
**  9) find the 'filesize' entry in the memory dump, and edit the filesize value below to match (case sensitive)
** 10) repeat steps 1 through 7 above, this time there should be no error message
