This script will program a T55x7 TAG with a configuration and four blocks of data.
It will then try to detect and read back those block data and compare if read data matches the expected data.


lf t55xx wipe
lf t55xx detect
lf t55xx write b 1 d 00000000
lf t55xx write b 2 d ffffffff
lf t55xx write b 3 d 80000000
lf t55xx write b 4 d 00000001

Loop:

try write different configuration blocks, and read block1-4 and comparing the read values with the values used to write.
