embeddedartists 2:2f4b7535ceb3 37 - For this test to work jumpers JP1..JP6 on the LPC4088 Experiment Base Board
embeddedartists 2:2f4b7535ceb3 38 must all be in positions 1-2, that is closest to the center of the board.
embeddedartists 2:2f4b7535ceb3 39
embeddedartists 2:2f4b7535ceb3 40 - The uSD card must be formatted as FAT or FAT32, NTFS will not work.
embeddedartists 2:2f4b7535ceb3 41
embeddedartists 2:2f4b7535ceb3 42 - This test expects a file with the name message.txt to exist in the
embeddedartists 2:2f4b7535ceb3 43 root folder on the uSD card. The file must be at least 10 bytes in
embeddedartists 2:2f4b7535ceb3 44 size and the first bytes must be eatest2014
